There are two sample motor sets depending on the needs of the experiment (weight , geometry etc). Micro-positioning devices are available for tomography.
A liquid helium or liquid nitrogen cryojet can be used for tomography measurements.
For XAS fluorescence experiments the Oxford Instruments Microstat HiRes Cryostat is used. This low-vibration cryostat be used either with liquid helium or liquid nitrogen. The clip-on stage can support thin samples mounted on sapphire discs of ~ 15 mm diameter. The x-ray visible part of the sample is apprx. 10mm across; samples with a diameter larger than 20 mm can be mounted but may not get to a uniform temperature throughout the sample. The sample chamber is in vacuum. The cryostat can be used in a helium bag for low energy measurements.
A quick guide for using the cryostat can be found here :
Currently on the beamline there are two 4-element Vortex silicon drift detectors both with a silicon chip of 1 mm therefore replacing the Ge Ortec for high energy measurements. In most set-ups the two detectors are used simultaneously.
Excalibur is the new diffraction detector on I18. It is a photon counting detector with low noise profile and an area of 115 x 100 mm2. It is used in transmission mode but if other geometries are needed please get in touch with the beamline staff.
These are filled with Helium and are now controlled through Stanford amplifiers. Instructions on how to set the sensitivity can be found in Users' Software Guide : EPICS.
