Oxford Cryostream 700R
Crystal Logic single axis diffractometer
Three different omega drives are available. The standard drive is a worm-driven spindle that can carry a large load with low runout and high angular accuracy. The maximum rotation rate for this spindle is approximately 25 degrees/sec. For high-speed centering and extremely low runout, an air-bearing direct-drive servo option is available. This spindle can rotate in excess of 360 degrees per second. A smaller direct-drive servo can be provided for applications where there is no significant load.
A vertical two-theta/detector distance stage is available. This robust stage will handle a 200 kg detector while providing ready access to the sample area. An alternative to the two-theta/distance stage is a simple two-axis translation stage.
k-goniometer head, Crystal Logic
Goniohead Brief Description
To allow for the implementation of an automated sample changer the Kappa-Phi axis module on the Crystal logic diffractometer was replaced by a single Omega axis. A kinematical mounted xyz goniometer head installed on the air-bearing direct-drive Phi axis allows for the automated sample z-translation and automated centering of the crystal in the beam. A fourth degree of freedom provides movements in the kappa space allowing the full coverage of reciprocal space. The control of this xyz goniometer head is integrated into the data collection software with assistance of the ALS Bio-instrumentation group and the NSLS Control and Detector group.
Annealing experiments are performed with an automated flash annealing device that was assembled at Brookhaven National Laboratory.
This inexpensive, simple device allows the blocking of the 100 K cryo-stream for a programmed amount of time. Users can set a time from 0.1-60 seconds. It also features a stop function if users decide to stop the annealing process before the programmed time.
The shutter is controlled by EPICS (Experimental Physics and Industrial Control System) and activated by air pressure.
The opening and closing time of this device is on the order of milliseconds, which is insignificant compared with the total annealing time.
The main advantage of the shutter is that allows a controlled instant re-cooling of the crystals and avoids significant turbulence induced by traditional annealing devices such as a piece of hard thin plastic.
