Conventional scanning X-ray microscopes find applications in all major research fields, in many cases approaching lateral resolutions mostly limited by the diffraction properties of microprobe forming optics. This limitation in lateral resolution can be surpassed by the so-called 'ptychography' approach, where coherent X-ray light is raster-scanned with high overlap across a specimen of interest. Diffraction patterns are recorded for each position of the raster scan and real-space images are reconstructed by computational methods.
I08-1 (previously named J08) is the Diamond soft X-ray ptychography instrument optimised for imaging and spectromicroscopy at higher lateral resolution than achievable with conventional scanning X-ray microscopes. The instrument shares beamline optics with the I08 instrument and will be operated in its final optimisation stage in the 250 -2000 eV photon energy range although we offer currently only radiation in the 500-1000 eV photon energy range for imaging and limited spectromicroscopy. The I08-1 instrument is designed for and will be upgraded to LN2 cryogenic specimen environments and ptycho-tomography in the future. Specimen mounts are compatible for both I08 and I08-1 branchlines.
I08-1 is already advanced in offering online live ptychographic processing tools that are steadily improved and upgraded according to requirements of experimenters.
Webinar on I08-1 soft X-ray ptychography
Join us on 22nd September 2021 from 14:00-16:00 BST at the I08-1 X-ray Ptychography Webinar that aims to demonstrate current and future capabilities of the I08-1 soft X-ray ptychography instrument along with extended Q&A sessions.
I08-1 calls for User proposals open
I08-1 is open for standard User proposals for AP31 (April - September 2022). Please visit the I08-1 beam time application or the Diamond User Office pages Additionally, a commissioning call will be opened soon for experiments during January - March 2022. Please note that the instrument is in its commissioning/ optimisation phase and only a limited number of imaging and spectromicroscopy modes can be offered. It is mandatory to contact the BL staff prior to submitting proposals.
