1 Scope

GB/T 42742-2023 sets the technical requirements for the L band 75 kW continuous wave magnetron. A CW magnetron at this power is not a kitchen component: it is the RF source of a particle accelerator or an industrial heating plant, running continuously at a power where the anode must be water cooled and the magnetic circuit is part of the tube. It is also a consumable with a definite life, so the warranty period and the life test are commercial terms rather than technical footnotes. The standard sets the requirements on the structure, the dimensions and electrode connections, the absolute maximum ratings, the operating conditions and typical characteristics, the general test conditions, the warranty period, the marking, the safety requirements and the appearance quality, followed by the quality assessment procedure, with an annex covering the filament continuity test, the life test, the judgement of non-operating defects and the efficiency calculation. It took effect on 1 December 2023.

This document specifies the performance requirements, quality assessment procedures, packaging and instructions, etc: of L-band 75kW continuous wave magnetrons: This document applies to L-band 75kW continuous wave magnetrons with frequencies of 896MHz, 915MHz, 922MHz, and 929MHz (with hereinafter referred to as "magnetron") production, testing, packaging and use:
