✦ Synopsis

An electronic system designed to collect and store the data of ten Hall probes, which are placed in a small gap between two identical superconductors to record the flux density distribution simultaneously, is described. The Hall voltages are collected by an analog multiplexer with a cycle period of 220 #s for a complete scan and stored in a small computer (NOVA 1200). The following data transfer to a PDP 11/45 enables the immediate evaluation of the data and their display on an XY-recorder or a screen.
