The booster control system is an integral part of the NSLS-II control system and is developed under EPICS. The booster control system includes six IBM Systems x3250 M3 and four VME3100 controllers connected via Gigabit Ethernet. These computers provide running IOCs for power supplies control, timing, beam diagnostics and interlocks. Also cPCI ADCs located in cPCI crate are used for beam diagnostics. Front-end electronics for vacuum control and interlocks are Allen-Bradley programmable logic controllers and I/O devices. Timing system is based on use of Micro-Research Finland Oy products: EVR 230RF and PMC EVR. Power supplies control use BNL developed set of a Power Supply Interface (PSI) which is located close to power supplies and a Power Supply Controller (PSC) which is connected to a front-end computer via 100 Mbit Ethernet. Each PSI is connected to its PSC via fiber-optic link. High Level Applications developed in Control System Studio and python run in Operator Consoles located in the Control Room. This paper describes the final design and status of the booster control system. The functional block diagrams are presented.

The NSLS-II booster is a full-energy synchrotron with the range from 200 MeV up to 3 GeV. The ramping cycle is 1 second. A set of electronics developed in BNL fro the NSLS-II project was modified for the booster Power Supplies (PSs) control. The set includes Power Supply Interface which is located close to a power supply and a Power Supply Controller (PSC) which is connected to EPICS IOC running in a front-end computer via 100 Mbit Ethernet. A table of 10k setpoints uploaded to the memory of PSC defines a behavior of a PS in the machine cycle. A special software is implemented in IOC to provide a smooth shape of the ramping waveform in the case of the waveform change. A Ramp Manager (RM) high level application is developed in python to provide an easy change, compare, copy the ramping waveforms, and upload them to process variables. The RM provides check of a waveform derivative, manual adjusting of the waveform in graph and text format, and includes all specific features of the booster PSs control. This paper describes software for the booster ramp handling.
