Advanced Diffraction & Scattering Beamlines (ADS-1 and ADS-2) UNDER CONSTRUCTION

The Advanced Diffraction and Scattering beamlines (ADS-1 and ADS-2) will provide high-energy X-ray diffraction and imaging capabilities for a range of scientific applications in materials science, engineering and mineralogy. The ADS beamlines are currently under construction and will be accepting user proposals in 2025.

Beamline Updates
  • 29/04/2024 – Our superconducting multi-pole wiggler (SCMPW) passed the Final Design Review milestone and will now enter the manufacturing phase. The SCMPW provides ADS with a powerful beam of high-energy X-rays, achieving a photon flux of up to ~1016 ph/s for ADS-1 users in white-beam mode. It is scheduled to replace the interim ADS wiggler in late 2025.

Ge detector test spectra
  • 27/03/2024 – The ADS-1 energy-dispersive detector was powered up and tested for the first time. We're very pleased with the outcome of the test, which demonstrated the detector's sensitivity even to very low photon counts emitted from an Am-241 source. Future work will include calibrating the detector to correct for small spectral differences among the 192 sensors in the array.

  • 25/03/2024 – The scientific computing team demostrated full software control of the ADS-1 detector gantry, including the ability to drive our two detector platforms simultaneously and independently. This work paves the way for detector movements to be integrated into experiment sequences.

ADS1 cabin computers
  • 07/03/2024 – A fun day for the team as we unpacked all our shiny new IT hardware in the ADS cabins. It's starting to look like a real beamline user space!

Yang Cao
  • 22/01/2024 – The ADS project is pleased to welcome Dr Yang Cao as a new member of the Beamline Scientist team. Dr Cao joins us from the Department of Chemical Engineering at the University of Melbourne, where her research focused on the use of 2D materials as a platform for nanoionic-related applications, including supercapacitors, Li-ion batteries, and flexible electronics. 


ADS insertion device installed
  • 22/12/2023 – Almost exactly a year after it was delivered, our interim wiggler (nicknamed "Bluey") reached its destination inside the storage ring. Squeezing the enormous device through the narrowest parts of the ring tunnel involved precision work by our technical teams, who did an excellent job manoeuvring Bluey safely into position. A brief news item about the Bluey installation can also be found on the BRIGHT Updates page.



Older updates (2023)
ADS PDS installation
  • 15/12/2023 – The epic task of installing the PDS hardware is finished. The work doesn't end here though – each section must be vacuum baked and exhuastively tested over the coming months.

  • 04/12/2023 – A team of metrology experts calibrated the ADS-1 detector gantry to correct for beam sag and other positioning errors. It’s now performing within expected tolerances and ready for service.

  • 10/11/2023 – Thanks to the efforts of our Scientific Computing and Controls teams, the ADS-2 capillary spinner is now functional. A robust rewrite of the original PD beamline auto-alignment routine enables the ADS spinner to align users' capillaries reliably in less than 20 seconds.


ADS PDS installation 1B

03/11/2023 – The big focus for ADS throughout October was the main installation of the PDS. Three engineers from Axilon visited to assist ANSTO’s staff and contractors with the mechanical setup, alignment surveying, electrical connections and basic motion tests. Many sections of the PDS are now sealed under vacuum, but some further work, such as final surveying of the two monochromators, is still to be completed.

ADS imaging detector
  • 16/10/2023 – The ADS-1 imaging microscope detector was assembled and passed its first benchtop tests (without X-rays).

ADS PDS shipping container
  • 12/09/2023 – Recent visitors to the Synchrotron might be wondering: what's inside the big blue box? The ADS photon delivery system – 20 tonnes' worth of shutters, filters, slits, monochromators and focusing optics, plus vacuum hardware and many other accessories – has arrived onsite after its long sea voyage from Germany. Installing all this equipment in the 1A and 1B hutches will take most of October, so stay tuned for further updates on the progress of the PDS.

Dectris detectors site acceptance test day
  • 26/08/2023 – Site acceptance testing of our Eiger2 and Pilatus3 detectors was completed with onsite support from Dectris. The detectors passed all their basic tests, and are now ready for integration into the beamline control and data processing pipelines.

  • 11/08/2023 – Engineers from Square One visited the Synchrotron to help install and test the main ADS-1 sample positioning table in hutch 1C. The modular design of this multi-axis system allows small samples on the upper (tomography) stage to be rotated at speeds of up to 600 rpm during data collection, while loads of ≤300 kg can be accommodated on the lower platform when the tomography stage is removed.

  • 10/08/2023 – Bilfinger Noell GmbH has been contracted to design and deliver a superconducting multipole wiggler (SCMPW) for the ADS beamlines. The SCMPW will enable ADS to achieve maximum targeted flux over the beamlines' full energy range (45–150 keV). The SCMPW will replace the interim permanent-magnet ADS wiggler in 2025.

Dectris detector unboxing
  • 02/08/2023 The ADS Science team had fun unpacking two very large shipping boxes containing our Eiger2 and Pilatus3 detectors, newly arrived from Switzerland. Everyone was relieved to see these expensive and delicate instruments safely bolted down on the test bench and flushed with dry gas to keep their internals free from moisture in preparation for power-up and initial testing. The Eiger2 and Pilatus3 will eventually serve as "workhorse" detectors for monochromatic diffraction experiments in ADS-1 and ADS-2, respectively.

ADS transfer pipe
  • 17/07/2023 – Construction of the ADS photon delivery system (PDS) has officially kicked off with installation of the transfer tube connecting our internal and external hutches. The 22.6-metre pipe will be pumped down and baked for up to a week to ensure the best possible vacuum before the lead shielding covers are reinstalled. The rest of the PDS hardware is due to arrive in September.

ADS gantry construction
  • 09/06/2023 –The 1C hutch is now home to our largest moving device: An 8-metre gantry system that will be capable of positioning the four ADS-1 detectors almost anywhere in the hutch. The gantry was assembled in place and surveyed for straightness before electrical wiring works commenced. Motion testing and calibration are scheduled for next month.

ADS flat panel test at IMBL
  • 08/06/2023 – The first test of an ADS detector with X-rays took place at the Imaging and Medical Beamline (IMBL). Happily, the test confirmed that our HS3131 flat panel detector is functioning and ready for more detailed calibration.

ADS PSS hardware
  • 12/05/2023 – Personnel Safety System (PSS) hardware for the ADS beamlines has arrived onsite. We might be the only beamline project at the Synchrotron that can fill a lab with E-stops and search points.

  • 21/04/2023 – Members of the ADS team spent almost two weeks at Axilon’s facilities in Cologne, Germany, witnessing factory tests on our beamline optics system. The visit was a great opportunity for both ANSTO and Axilon to identify any remaining issues before the system is shipped to Melbourne. Seeing our critical beamline hardware assembled and working was an exciting moment for the team – ADS is now another step closer to reality!

ADS1 Transfer line and stairs
  • 24/03/2023 – Staff and users of beamlines adjacent to ADS are now benefiting from increased physical exercise thanks to the installation of shielding and supports for the ADS-1 beam transfer tube, and a new staircase providing access over it. (You're welcome!) This is the final piece of external shielding for the beamlines and marks the end of the ADS hutch construction project.

ADS extension building
  • 01/03/2023 – An exciting milestone was achieved with the Occupancy Permit being issued for the ADS-1 extension building. We’re very pleased with our new space and looking forward to filling up the interior with all the accoutrements of a cosy user cabin.

ADS wiggler lift
  • 08/02/2023 –The interim ADS wiggler was lifted by crane over the storage ring and into the crescent. Much careful planning and preparation went into the operation, which went without a hitch and provided an entertaining morning for spectators from around the Synchrotron. Well done to the engineering and mechanical tech teams for a safe and successful lift!  

  • 07/02/2023 – LAB Motion Systems has been contracted to design and supply a motorised goniometer for single-crystal diffraction experiments on ADS-1 and ADS-2. The goniometer allows continuous 360° rotation about two axes (omega and phi, fixed 50° apart) and will support sample environments of up to 2 kg for in situ data collection.

ADS-2 endstation design
  • 18/01/23 – CNC Design Pty Ltd have been contracted to develop and install the safe motion control system for the ADS-2 sample and detector platforms. The detailed design of the ADS-2 endstation is nearly complete and many hardware components have been ordered.

Capability Summary and Techniques

In comparison to X-rays with lower energies, high-energy X-rays (≥ 45 keV) penetrate more deeply into matter, and are absorbed more weakly and scattered at smaller angles by the sample. This makes them particularly suited to the study of:

  • Samples inside complex sample environments for in situ or operando studies
  • Samples containing heavy elements where strong X-ray absorption is problematic
  • Internal features of bulky samples, such as defects and strain

ADS-1 and ADS-2 will offer highly flexible experiment configurations and sample environments to enable a wide variety of materials characterisation experiments using high-energy monochromatic and polychromatic X-rays. The optics layout will maximise the flux at the sample position while offering variable beam sizes and focussing. 

The planned timeline for the construction of ADS anticipates user experiments starting in 2025.


The capabilities of the ADS beamlines will include:

Monochromatic beam experiments

  • Rapid in situ powder diffraction measurements using a range of sample environments (high/low temperature, high pressure, gas flow, etc.) with the benefits of increased sample penetration and high momentum transfer
  • Total scattering measurements (PDF) for samples with short-range ordering
  • Single-crystal diffraction experiments on large and/or strongly absorbing crystals, or crystals in complex sample environments with limited angular access for the beam (e.g. diamond anvil cells, furnaces)
  • Rapid texture analysis and 2D materials mapping
  • Imaging and tomography

White/pink beam experiments (ADS-1 only)

  • Energy-dispersive diffraction and high-resolution 3D strain scanning
  • Imaging and tomography
  • Laue diffraction


The ADS high-energy X-ray beam will be split using a side-bounce monochromator to serve two independent beamline endstations, ADS-1 and ADS-2.

ADS-1 will offer white, pink and monochromatic X-ray diffraction and imaging capabilities with a monochromatic energy range of 50 – 150 keV. A multipurpose array of detectors with a highly flexible positioning system (sample–detector distances of 0.3 – 4 m) will facilitate a wide range of experiments, including those combining multiple data types (e.g. diffraction and imaging). The ADS-1 sample stage assembly will support loads of up to 300 kg and offer fast rotation speeds suitable for tomography. Larger user-supplied equipment can also be accommodated. A range of flux, band-pass and beam size options will be available depending upon energy and optical configuration. 

ADS-2 will be capable of monochromatic diffraction experiments at three fixed X-ray energies (45, 74 or 87 keV). It will be suited to techniques such as powder diffraction, single crystal diffraction, total scattering (Pair-Distribution Function analysis) and high-throughput applications with a range of standard sample environments. The ADS-2 sample stage assembly will accommodate samples and environments of up to 100 kg.

Both beamlines will have controlled hutch environments, multiple standard sample environments spanning a wide temperature range, gases available for experiments, and a fume extraction system.

For further information, see ADS Technical Specifications.

Scientific Applications

The ADS beamlines will be well suited for in situ bulk structure characterisation as well as for spatial mapping of samples such as metals, ceramics, minerals and composites.  In situ capabilities and rapid data collection regimes will also enable time-critical kinetics studies on the second and millisecond timescales for processing and aging experiments.

Materials Science
  • Structural studies of strongly-absorbing inorganic materials
  • Characterisation of structure-function relationships in component materials of energy storage, production and conversion systems – batteries, fuel cells, thermoelectric materials, etc.
  • In situ structural studies of stimulus-responsive materials, sorbents, catalysts, etc.
  • Studies of local atomic structure variations using total scattering analysis or single-crystal diffuse scattering
  • Combined diffraction and imaging mapping of in situ materials processing experiments
Engineering and Manufacturing
  • Non-destructive characterisation of fractures, textures, strains and deformations in large manufactured objects across the energy, automotive, transport, defence and aerospace sectors
  • Studies of crack propagation in both small and large components around heat-affected areas such as welds
  • In situ studies of cyclic mechanical tension/compression for understanding failure mechanisms relating to fatigue in engineering infrastructure, e.g. materials produced by additive manufacturing
Earth Science
  • Studies of mineral formation and recovery under extreme conditions of temperature and pressure 
  • Combined diffraction and imaging mapping of minerals
