The system is comprised of a data input subsystem, a display subsystem and a spectrometer control subsystem. The data input subsystem consists of a two-dimensional analog-to-digital converter with the analog section remote from the rest of the system. The analog-to-digital converter clock runs at 100 MHz. There can be up to 1024 channels in each dimension for a maximum array size of ~ 1 million words. Arrays of this size may be easily handled by a multiport memory with 6.71 Ã 107 words of address space. The read/increment/ write time for data in this array is 2.5 Â¿sec per event. The display and neutron spectrometer subsystem are also briefly described.
