SRM
2G Superconducting Rock Magnetometer (SRM-855) with RAPID Sample-Handler System
Magnetometer for measuring discrete samples with both demagnetizing and magnetizing capabilities. The magnetometer uses super conducting quantum interference devices (SQUIDs) operating at 4.5 K to detect minute magnetic moments. Fully automated and capable of running 99 individual samples per batch.
The SRM is hosted in the Magnetically Shieled Room (MSR) in room K-004. Its main components are the magnetometer itself, the sample handling frame, and computer host. The magnetometer relies on pressurized helium gas provided by the Cryomech Helium compressor which is in turn cooled by a water-cooled Lauda chiller. Both of these units are hosted inside the climate controlled outside shed. Also located inside the shed, is the vacuum pump which is controlled by the SRM electronics to pick up individual samples.
