INTELLECTUAL CRATE-CONTROLLER K167

This paper describes hardware and software of ICC-controller K167, developed for mod- ernization of Kurchatov synchrotron radiation source (KSRS) automated control system (ACS). K167 is based on SBC-computer of miniMODUL167 type, programmable logical integrated circuit CPLD XC95288XL and being controlled by RTX-166Full V4.0 RTOS. Controllers K167 are installed into 18 crates and connected to the LAN server of ACS (automated control system) through CAN-bus. They will control CAMAC devices devel- oped in Budker Institute of Nuclear Physics SB RAS.

P.56. Grekhov O.V (Moscow, Russia) IST DISTRIBUTED DAQ SYSTEM FOR INR LINAC

The INR Linac is intended for acceleration of H+ and H- ions. DC power supply of quad- rupole doublets of the INR Linac is realized by means of stabilized current sources (SCS) IST type. The Distributed Data Acquisition (DAQ) System, based on ADAM blocks (5000/485), was designed and put into operation for the SCS distance control. In this pa- per the structure, right choice of communication protocol and hardware are specified. In process of DAQ system designing some peculiarities of SCS operation was taken into ac- count: placement of SCS at a long distance (more then 300 m) and work in conditions of high electromagnetic disturbances.

ENHANCEMENT OF VACUUM MONITORING SYSTEM OF KCSR ACCELERATOR FACILITY

The vacuum monitoring system of Kurchatov Center of Synchrotron Radiation is built on current measuring of sputter ion pumps mounted over vacuum chambers of accelerating units. Measuring hardware designed in INP SB RAS is using CAMAC standard and has been operating for a decade now. Hardware upgrade is accomplished by installing a PC workstation, connected through CAN bus to an in-house crate controller. Developed soft- ware comprises three levels. Firstly, there is a low-level program running inside the crate controller under RTX-166 operational system. Secondly, we have SQL Server database with client program, whose function is to create the queries at workstation side. And fi- nally there are high-level applications running over network needed to display a current facility status and a data processing.
