  This paper presents the design of the National Synchrotron Light Source II (NSLS-II) Power Supply Controller (PSC). It consists of a main board, rear module and backplane. The main features of NSLS-II PSC included 256MB DDR2 memory for power supply system diagnostics, high speed serial link between PSC modules, an embedded microprocessor and a 100 Mbps Ethernet port. Each PSC module can be remotely programmed through network. NSLS-II PSC will be used to control power supplies in Storage Ring, Booster Ring and Transport line. The PSC also provides interface for the NSLS-II fast and slow orbits feedback system.

There are 60 12×150A current leads distributed in 6 RHIC service buildings; each current lead delivers power supply current from room temperature to cryogenic temperature in RHIC. Due to the humid environment, condensation frequently occurs and ice was quickly formed during operation, especially during an extensive storage period. This condition generated warnings and alarms that personal had to respond to, in order to provide temporary solutions, to keep the machine operational. A temperature control system was designed to avoid such occasions. We will discuss design, implementation and some results of this design in this paper.
