.2 M219 Continuous Wave Magnetron Stability Study

With the continuous development of society, the advances of science and technology, microwave ovens have entered every family, and become one of the most commonly used household appliances. The development of microwave ovens leads to that of the magnetron, makes the demand of magnetron continues year by year. It brings not only the opportunities but also the challlenges to magnetron manufacturers. As most of the microwave ovens are in European developed country, the quality of the microwave is in very strict requirements. What firstly determines the quality of the microwave ovens is magnetron's quality ,and the stability of the magnetron determine the stability of microwave ovens directly, which is why for many manufacturers magnetron, it is essential to upgrade the magnetron stability within limited cost space.This paper aims at the stability of the magnetron, basing on the principle of magnetron, connecting with the production process nowadays, analyses the various causes of instability of magnetron, and responses to variety of factors to have a experiment test, to identify the measures to improve and ultimately enhance the stability of existing products. The summary is as followed:1. Study the causes and mechanism of instability.2. Combined with the existing production process, in theory, advance the program to improve the stability of the magnetron.3. Improve the production process of magnetron and put up enough experiment to confirm the validity of the full improvement.4. Carry out the mass production process after improvement, and to form some technical documents.
