SYSTEM FOR ACQUIRING THE DATA OF A MULTICHANNEL SUPERCONDUCTING QUANTUM INTERFERENCE DEVICE SIGNAL, CAPABLE OF PREVENTING THE INFLOW OF EXTERNAL NOISES OR THE GENERATION OF CLOSED CIRCUIT NOISES

摘要

PURPOSE: A system for acquiring the data of a multichannel superconducting quantum interference device(SQUID) signal is provided to prevent the generation due to a closed circuit between an analog signal processing system and a data acquiring board.;CONSTITUTION: A digital converting part(300) acquires voltage signals from a plurality of channels and generates a channel-voltage serial digital signal including information related to the outputting channel of the voltage signals and information related to the voltage signals. An optical fiber cable(400) transmits the channel-voltage serial digital signal from the digital converting part. An SQUID sensor(200) is installed in a shielding room(100) shielding electronic wave or electromagnetic wave.;COPYRIGHT KIPO 2011
