Fast Access at Beamline ID19: Microtomography ("resubmission")

The experimental programme at beamline ID19 underwent tremendous changes in the more than 20 years of operation: starting from Bragg diffraction
topography (already with a substantial contribution of in situ experiments), the beamline pioneered hard X-ray phase contrast microtomography in routine user
application, later coupled with polychromatic illumination to exploit hard X-rays up to 250 keV as well as short exposure times. Here, we propose an access route
for routine microtomography which is fast, i.e. can be made available on short terms, and requires minimal overheads for the beamline staff. The basic idea is to
deploy the robotic sample changer of the beamline which has already proven to be a useful tool during the pandemic where users remotely scanned and changed
samples. It can be easily installed, with samples pre-mounted from the users loaded and made available in non-used evening and night shifts in a remote manner
exactly like it was done during the pandemic.
