HV Control

Control systems for the LeCroy HV4032a and REPIC RPH32010 power supplies with Graphical User Interfaces (GUIs) written in Tcl/Tk. The LeCroy HV4032a system is used for the photo multiplier tubes (PMTs) of Grand Raiden and Focal Plane Polarimeter, and the REPIC RPH32010 system is used for those of Large Acceptance Spectrometer and Beam Line Polarimenters.

Device (Motor) Control

A new control system for the movables devices such as slits installed in the two-arm spectrometers, Grand Raiden and Large Acceptance Spectromter, and WS beam line. All the instruments are controlled by the system through a Local Area Network (LAN), which allows full control on remote computers.

Magnet Control

The system controlls not only the magnets of the two-arm spectrometers, Grand Raiden and Large Acceptance Spectrometer, but also RF transition units of the High Intensity Polarized Ion Source (HIPIS). A high performance feedback system based on a Proportional Integral Differential (PID) argorithm was implemented.

Terminal Server

A newly installed Linux-based terminal server connects multiple RS-232 ports to the Ethernet Local Area Network (LAN) You can control an equipment with a RS-232 interface throuth our LAN with this module. Now we support the CAEN HV power supplies such as SY403, and the Oriental Pulse Motor Drive Units such as VEXTA SPG8800.
