The National Synchrotron Light Source II is under construction at Brookhaven National Laboratory, Upton, USA. NSLS-II consists of linac, transport lines, booster synchrotron and the storage ring. The main features of booster are 1 or 2 Hz cycle and beam energy ramp from 200 MeV up to 3 GeV in 300 msec. EPICS is chosen as a base for the NSLS-II Control System. The booster control system covers all parts of the facility such as power supplies, timing system, diagnostics, vacuum system and many others. Each part includes a set of various electronic devices and a lot of parameters which shall be fully defined for the control system software. This paper considers an approach proposed for defining some equipment of the NSLS-II Booster. It provides a description of different entities of the facility in a uniform way. This information is used to generate configuration files for EPICS IOCs. The main goal of this approach is to put information in one place and elimination of data duplication. Also this approach simplifies configuration and modification of the description and makes it more clear and easily usable by engineers and operators.

Being responsible for 3 GeV booster synchrotron for the National Synchrotron Light Source (NSLS-II, BNL, USA) design and manufacture, Budker Institute of Nuclear Physics also designs the booster control and diagnostic system. Among others, the system includes interlock system consisting of equipment protection system, vacuum level and vacuum chamber temperature control system, beam diagnostic service system. These subsystems are to protect facility elements in case of vacuum leakage or chamber overheating and to provide subsidiary functions for beam diagnostics. Providing beam interlocks, it processes more then 150 signals from thermocouples, cold and hot cathode vacuum gauges and ion pump controllers. The subsystems contain nine 5U 19" chassis with hardware of each based on Allen-Bradley CompactLogix Programmable Logic Controller. All the interlock related connections are made with dry contacts, whereas system status and control is available through EPICS channel access. All operator screens are developed with Control System Studio tooling. This paper describes configuration and operation of the booster interlock system.

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.

When operating a multicomponent system, it is always necessary to observe the state of a whole installation as well as of its components. Tracking data is essential to perform tuning and troubleshooting, so records of a work process generally have to be kept. As any other machine, the NSLS-II booster should have an implementation of monitoring and archiving schemes as a part of the control system. Because of the booster being a facility with a cyclical operation mode, there were additional challenges when designing and developing monitoring and archiving tools. Thorough analysis of available infrastructure and current approaches to monitoring and archiving was conducted to take into account additional needs that come from booster special characteristics. A software extension for values present in the control system allowed to track the state of booster subsystems and to perform an advanced archiving with multiple warning levels. Time stamping and data collecting strategies were developed as a part of monitoring scheme in order to preserve and recover read-backs and settings as consistent data sets. This paper describes relevant solutions incorporated in the booster control system.

All software of control system, starting from hardware drivers and up to user space PC applications, needs configuration information to work properly. This information includes such parameters as channels calibrations, network addresses, servers responsibilities and other. Each software subsystem requires a part of configuration parameters, but storing them separately from whole configuration will cause usability and reliability issues. On the other hand, storing all configuration in one centralized database will decrease software development speed, by adding extra central database querying. The paper proposes configuration tool that has advantages of both ways. Firstly, it uses a centralized configurable graph database, that could be manipulated by web-interface. Secondly, it could automatically export configuration information from centralized database to any local configuration storage. The tool has been developed at BINP (Novosibirsk, Russia) and is used to configure VEPP-2000 electron-positron collider (BINP, Russia), Electron Linear Induction Accelerator (Snezhinsk, Russia) and NSLS-II booster synchrotron (BNL, USA).

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.
