Oxford Cryostream 700R

Oxford Cryostream 700R Controller and Dewar

[edit] Brief Description: The cooled nitrogen stream is provided by an Oxford Cryostream 700 series from Oxford Cryosystems. A liquid Nitrogen dewar supports the Oxford Cryostream controller and the superdryer device. This dewar is refilled automatically. The Oxford Cryostream 700 series is composed of two devices the head fitted on the standed flowing the nitrogen stream on the sample and the controller. The controller provides access to the main function of the Cryostream. The Oxford Cryostream head is fitted on a three axis device allowing the perfect alignment of the stream on the sample. [edit] Specifications * Temperature range:: 700 series Cryostream, 80-400 K * Liquid nitrogen consumption:: 0.6 litres/hour at 5 litres/minute gas flow 1.2 litres/hour at 10 litres/minute gas flow * Temperature stability:: 0.1 K * Effective length of cold stream:: >15mm (distance from end of nozzle at which cold stream is within 1K of set temperature) * Coldhead weight:: 5kg * Length of transfer line:: 700 series: 2350 mm, of which 1450mm is flexible transfer line & 900 mm is rigid leg. * Cold stream nozzle size:: 7 mm * Controller weight:: 7.1 kg * Controller size:: 135 mm x 244 mm x 287 mm * Mains power supply:: 230 Vac 50Hz or 100/115 Vac 50/60 Hz * Power consumption:: 500VA * Recommended Dewar size:: 60 litres for 700 serie

Crystal Logic single axis diffractometer

Crystal Logic single axis diffractometer

Brief Description:

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

Gonio Head

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

Annealing

Brief Description:

Annealing experiments are performed with a new device, the Cryo-Shutter, which was fabricated at Brookhaven National Laboratories.

The Cryo-Shutter is a simple device that allows blocking for programmed amounts of time of the 100K nitrogen stream that surrounds the sample.

The shutter is controlled by EPICS (Experimental Physics and Industrial Control System) and activated by air pressure.

The opening and closing time of the Cryo-Shutter is of 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.
