Undulator Controls
The LCLS undulator line consists of a series of 33 identical undulator segments.
The control and monitoring equipment for each segment will reside in a 19” rack
located beneath each undulator girder. Three separate units will be housed in that
rack – the Motor Power/AC interlock chassis, the Undulator Control Module,
and the Undulator Control Module Interface chassis.

UCM - Translation Stage Skew Monitoring
Translation stage comparator circuit inside the UCMI Chassis
Two levels of transverse skew interlock intervention
Level 1 threshold, when motion begins to get outside of acceptable alignment
UCM enters alarm state which requires operator intervention
One motor individually moved to match other motors position
Level 2 threshold, if the magnitude of the skew continues
AC interrupt chassis is tripped, cuts power to all motors
UCM enters alarm state which requires engineering intervention
Calibrated alignment of stage positions
Level 1 and Level 2 have a single alignment adjustment
Level 1 and Level 2 have independent threshold adjustments
Level 2 violation will require a tunnel access to visually inspect the
problem
