Data Selector Group Sequencer Interface

A CAMAC-based module for high rate data selection and transfer to Tracor Northern TN-1700 multichannel analysis system is described. The module can select any group of 4096 consecutive addresses of events, in the range of 24 bits. This module solves the problem of connecting a number of time digitizing systems to the memory of a multichannel analyzer. Continuous processing rate up to 200,000 events per second along with the live display make the testing of the above systems very efficient and relatively inexpensive. The module also can be programmed for storing the preset group of addresses into more than one section of the inemory. The events are analyzed in each section of the memory during the preset time. Multiple spectra can thus be taken automatically in a sequence.
