Abstract
A traveling‐wave maser tunable over the frequency range of 1340 to 1430 Mc has been developed and constructed for use in radio astronomical research. It uses ruby as the maser material and a comb as the slow‐wave structure. The net gain exceeds 30 dB over most of its tuning range, while the average instantaneous bandwidth is about 11 Mc. It has been designed for operation at 4.2°K.Keywords
