摘要
A monochromator is important to a beamline for desired monochromatic light. There are three water-cooled double crystal monochromators(DCMs) commissioned in the phase-I beamlines of Shanghai Synchrotron Radiation Facility(SSRF). In this paper, the mechanical principle of the DCMs is introduced. A control system for the monochromator based on the standard architecture for SSRF beamlines is described. To achieve the control requirement precisely, the hardware includes VME(Versa Module Eurocard)-based controller for stepper motors, RS-232-based controllers for micropositioning and piezoelectric actuators. The software is developed with EPICS(Experimental Physics and Industrial Control System) package. Test results have revealed the stability and reliability of the system.
