Table 1. Basic beamline parameters.
Source | Bending magnet (1.3 T); E (critical) 7.95 keV |
Hutches | Centred at ~15 m, ~24 m & ~31 m |
Energy range | 8 – 40 keV (+ filtered-white & pink) |
Monochromator (DMM) | 3 multilayer stripes: ∆E/E ~ 0.5% & 3% |
Mirror (VBM) | Single-bounce vertical, bendable (concave & convex); 2 stripes |
Beam size | Max. 44 mm (H) x 6.6 mm (V) at 22 m, 64 mm (H) x 9.6 mm (V) at 32 m |
Detectors | CMOS- & CCD-based with scintillators & specialised magnifying optics |
MCT photon-delivery modes:
white beam;
monochromatic beam (8 -> 40 keV with 3% band-pass or 8 → 20 keV with 0.5% band-pass) delivered by double-multilayer monochromator (DMM);
pink beam delivered by vertical-bounce mirror (VBM) to cut off high-end energy.
monochromatic beam in conjunction with VBM to increase the beam in vertical direction;
Imaging detectors :
white-beam detector – for all delivery modes;
mono-beam detector – for X-ray energies ≤ 20 keV.
high speed detector - for higher than 100fps
A variety of scintillators and objective lenses are available to accommodate user requirements for collection efficiency, spatial resolution, and field-of-view. The final performance is ultimately constrained by the detector's field of view (FOV) and the beam size.
A separate table-mounted shutter will be available if needed, along with two ionization chambers for monitoring beam flux. For radiation-sensitive samples, a calibrated dosimetry system is available to address dose rate concerns.
Both “step-&-shoot” & “on-the-fly” scan modes for CT data collection are available.
CT datasets can be be reconstructed at the beamline using the ASCI high-performance computing system, which features dedicated compute nodes and specialized software developed for this purpose. Additionally, more detailed data processing, analysis, and visualization can be performed remotely via ASCI after the experiment concludes. See next page for → MCT Data Processing
It is essential for those planning to submit experiment proposals for the MCT beamline to consult with beamline staff to discuss the technical details and feasibility before finalizing their submission.
