Traveling-wave maser uses superconducting magnet

A 70-kmc traveling-wave maser that uses a superconducting magnet for the applied field is being developed by the Westinghouse Electric Corp. The superconducting magnet, now in use, provides the high-field uniformity that is important to high-gain maser operation of broad bandwidth, high frequency and high sensitivity. The new maser device, with a pump frequency of 118 kmc, will be used to investigate advanced radiometers, radar, and communications equipment.
