Data
Acquisition (DAQ) System
The VME modules
controlling ADC(FERA) and TDC(3377) modules for the spectrometers, Grand
Raiden and LAS, and for the beam line polarimeters and transferring data to
the high speed memory were renewed at 2004. The new operation system is based
on the user friendly UNIX. This manual includes the procedures how to
initialize and run the ADC and TDC modules. |
The TamiDAQ
system, an older DAQ system, provides the framework of the current DAQ system
for Grand Raiden, LAS, and the beam line polarimeter. A very high-speed data
taking was achieved by this system. |
Trigger System (in Japanese) The trigger
circuit is controlled by the Universal Logic Module consisting of the field
programmable gate-array (FPGA) chips. Several sets of the circuits are
prepared, which covers most experiments using Grand Raiden or LAS. Individual
experiments need to select the proper set. |
