Description

Experimental endstations often have large mechanical components that can have complex
motion control requirements.

The CHX (Coherent Hard X-ray Scattering) beamline at NSLS-II has a long SAXS
table with six axes of motion. The table consists of two separate sections, which can be
operated independently or in a combined mode. The table can rotate around the sample
position and translate in the direction of the scattered beam. Rotations require up to four
motors to be coordinated. Equipment and personnel protection interlocks are included in
the control system.

The SIX (Soft Inelastic X-ray Scattering) beamline at NSLS-II has a 15 m long spectrometer
arm that can rotate around the sample through an arc of 120 degrees. Rotation of the
spectrometer arm requires coordination of two motors and integration with an equipment
control PLC. Equipment and personnel protection systems are integrated with the motion
control.

These motion applications are implemented in Delta Tau Turbo PMAC motion controllers. Personnel safety interlocks are implemented in an Allen Bradley Guard Master configurable safety relay. Operation and status of the motion systems are integrated using EPICS and CS-Studio.
