Sample Environments


The Brockhouse beamlines share several sample environments. If you'd like to use one in your next run, please mention it in your proposal.

 

Oxford Cryostream 800 Plus

Provides temperature control from 80 – 500 K (-193 – +226 ºC) by blowing dry gas over the sample. We have two of these on mobile carts. They can be used on all three beamlines.

High Temperature Flow Cell

Provides temperatures up to 1070 K (+800 ºC) with gas flow for capillary format samples. Based on the design of P. Chupas (P. J. Chupas et al., J. Appl. Cryst. 41, 822 (2008)). Quartz capillaries are available at the BXDS beamlines. This cell can be used on all three beamlines.

Dual Sample Higher Temperature Flow Cell

Temperatures up to 1273 K (+1000 ºC) with gas flow. Samples are in capillary format, and two can be loaded at a time. Quartz capillaries are available at the BXDS beamlines. Also based on the P. Chupas design (P. J. Chupas et al., J. Appl. Cryst. 41, 822 (2008).

Helium Cryostat

Advanced Research Systems, Model DE202A-G-T. Enables low temperature experiments down to 10 K (-263 ºC), with a beryllium dome over the sample. The mounting is very specific to the Huber endstation in SOE-1. Other implementations may be possible with advanced notice.
