MD2 Centering Stage Repair

The centering stage for the 24-ID-C MD2 has been repaired by Maatel and re-installed.  It is working fine with no missing steps on X and Y slides.

MD2 Centering Stage Repair

Also during the last run cycle, we noticed that the centering stage on the 24-ID-C MD2 exhibited a level of slippage which made it unacceptable for use with crystals smaller than 10 microns.  This slippage may be a result of mechanical damage suffered by the MD2 during its initial shipment to NE-CAT which has worsened over time.  As a result, we have sent the centering stage to Maatel.  They have received it and are looking it over.  During the interim, Maatel has loaned us a centering stage.

October Status Update

Update on High Capacity Sample Automounters

The linear servo for the new sample automounters has arrived.  It has been tested and is functioning to our expectation. This linear servo will replace a pneumatic motor for the long, linear motion between the sample storage dewar and the goniometer.  The linear servo has the advantage of continuous monitored feedback, adjustable distance of the actuator move, and adjustable speed and acceleration of the actuator move.

June Status Update

As stated in the previous status update, moving to the new piece of software to control the MD2 hardware is a necessary step in implementing shutter-less vector scans (kinematic scans) and taking full advantage of the speed of the PILATUS-6MF.  As a first step, during the May shutdown, shutter-less continuous vector scans became a reality.  It is now possible to perform continuous vector scans on 24-ID-C beamline without closing the shutter while the MD2 moves the crystal to a new position.
