Abstract

This paper describes the hardware of the 24-channel SQUID magnetometer being completed in the Low Temperature Laboratory. The overall system, including computer hardware and software, is discussed elsewhere (Hämäläinen 1989). The instrument will be used in a magnetically shielded room for brain research. We hope that this apparatus will enable us to locate current sources underlying evoked magnetic fields without moving the dewar.
