Processing Data from the Scaler/Timer Type 6255

摘要

The Scaler/Timer type 95/6255-1 is now extensively used for nucleonic counting applications since, in conjunction with other units in the Harwell 6000 Laboratory Series, systems can easily be assembled to meet a wide range of counting requirements. The 6255 is microprocessor-based and contains comprehensive counting and timing facilities (eg 2 scalers, 2 timers, 4 ratemeters, multiple cycle operation, control of other 6255's and RS232C output) and was intended for counting, printing and logging operations; the unit does not, therefore contain facilities for processing data. However, in some applications processing of the data accumulated in the 6255 is needed, for example, for removal of background, for statistical tests etc, and the design of the 6255 enables this to be carried out with a low-cost microcomputer. This report illustrates how this can be done, using the Commodore VIC computer as an example. (Atomindex citation 15:039363)
