Abstract

PURPOSE: To highly accurately attain multipoint simultaneous measurement even when the number of channels is increased by using a rapid superconductive counter as a counter and selecting and optional channel by a superconducting multiplexer capable of executing rapid operation.
CONSTITUTION: Counters 7, 8 constituted of superconducting circuits are connected to respective SQUIDs 1, 2 for outputting pulses in accordance with the quantity of magnetic flux and the counter output values of respective channels are time-divided by the superconducting multiplexer 9 to select respective channels. Since the counters 7, 8 always rapidly count up the outputs of the SQUIDs 1, 2 in each channel, their count values can be instantaneously outputted when a certain channel is selected by the multiplexer 9. In addition channel selection can rapidly be executed.
