Caladium Beckhoff

XY stage motors:  The telescope + DUT assembly are mounted on a remote controllable base "coarse" XY control  (X=horizontal transverse to beam; Y=vertical) to align the whole assembly wrt beam. During new test beam periods, this is typically done initially using a pair of alignment lasers in conjunction with fiducial markers to center to expected beamline within a few mm. The vertical position is gauged by a laser mounted on the tunnel side wall. The horizontal position is gauged by another laser hanging the ceiling near the side entrance. Once positioned close enough, the refined alignment is done with the beam data in telescope. For both laser alignment and beam alignment, the position adjustments for the whole telescope (including DUT mounted within it) is done with the dedicated Caladium XY stage Beckhoff26 subpanel shown on the right. The base XY stage for the whole telescope + DUT is controlled by the "coarse" X,Y adjustments. +X is pointing away from the ESA entrance gate; +Y is pointing up. The Spring/2016 upgrade added a "fine" XY stage for the DUT to allow additional adjustments of the DUT with respect to the telescope. There is an additional optional DUT rotational stage control. 

Temperature

The Caladium upgrade also added some temperature sensors that can be plugged into desired parts of the DUT setup. The displays for them are on the "KL3314 temp" tab of the Beckhoff panel.
