P61B Large Volume Press (DESY)

Location of beamline P61 and end station P61B in the Paul P. Ewald hall.

P61B logo

The Large Volume Press (LVP) extreme conditions station uses synchrotron X-ray radiation in a continuous energy range of 30–160 keV. The station combines ED-XRD and Radiography Imaging for in situ measurements under extreme conditions of high pressures and temperatures.

Updated 2025.05.26

Application of high load and temperature may cause WC anvils to break, resulting in a shock to the press stages and a blow out of materials. Please follow the rules below:

  1. During heating or deformation, someone must be present in the CH. (Unattended compression and decompression is permitted.)
  2. UHP experiments (>30 GPa) MUST use a graphite or aluminium plate attached to the diamond exit window to shield it from blow-out shrapnel.
  3. Do not increase the press load significantly beyond the sample pressure in the proposal. Recognize when pressure generation becomes inefficient and do NOT increase load further.
  4. Always enter a complete pressure profile for the master ram with an up-ramp, a dwell, and a down-ramp, to ensure the PLC is in control of the rams at all times.

Should a blow out occur during a normal experiment, your local contact will assess and resolve any issues. Be mindful that some beamtime may be lost after a blowout.
