MEX1 Cryostat
FOR PROPOSALS: PUT “CRYO”, “CRYOSTAT” ETC IN YOUR PROPOSAL TITLE
Beamline | MEX-1 |
Temperatures | 7.4 - 298 K Up to 500 K if usp g the heaterto 500 K if usp g the heaterto 500 K if using the heater |
Cool down and alignment time between sample changes | ~ 20 mins |
Modes | Fluorescence and transmission |
Energies | 5 - 13.5keV good spectra < 5 keV achievable but noisy |
Circular: six 7 mm diameter pellets Rectangular: nine 7 mm x 3.5 mm pellets Customised: contact us |
Example data:
Zn K edge: From room temperature (298 K) to 8 K. Spectral resolution increases as temperature decreases.
Sample stick:
Cryo stick. This gets inserted into the cryostat
Top of the cryo stick, which forms a seal to maintain the sample well environment
The copper tip of the cryo stick has a heater and temperature sensor mounted within
Sample holders:
Considerations
The sample plates (clear) are screwed onto the cryo tail (brown). Contact us if you require the correct size sample plates.
