QMC Instruments Ltd

QMC Instruments Ltd. core activity in its early years was the design and manufacture of liquid helium cooled InSb hot electron bolometer systems. This device had previously been used as a heterodyne receiver for far infra-red (FIR) astronomy. In the commercial environment QMC developed this into a crucial tool for the plasma fusion community to measure electron density and temperature profiles within experimental Tokomak reactors. Early work was carried out at JET in Oxfordshire (UK) and at Princeton in the US.
