JULIOS detectors combined to a PB-based data acquisition system

The linear JULIOS scintillation detector system, which is constructed for simultaneous position and time encoding of registered events, is extended and combined to a flexible and high capacity PC-based data acquisition system. A new timing interface module in the JULIOS electronics and a new memory module in the EISA-PC are based on user programmable logic cell arrays in the form of Xilinx XC4010 chips. The available address space can be flexibly allocated to maximum of 12 bit position and 16 bit time channels. The standalone detector and data acquisition system is aimed at pulsed source instruments performing high resolution angle-dispersive time-of-flight experiments. Specific ex operational aspects of the system, which is installed at the redesigned ROTAX instrument at ISIS, are discussed. (author) 4 figs., 9 refs
