Flyback transformers. In contrast to OBITs and MOTs, flybacks cannot be connected to the mains directly. They work at a frequency of about 20kHz, whereas the mains has only 50Hz. The higher frequency has many advantages, such as smaller, lighter cores, smaller caps for rectifiers etc., but it makes an electronic control circuit necessary. It means the use of affordable microwave oven transformer instead of the sophisticated high voltage unit. An additional bonus will be that one can slightly increase the working pressure and thus reduce the quality of the vacuum pumps being used, and also prolong the lifetime of the gas mixture. A microwave oven is basically just a high-power microwave transmitter that dumps its energy into a faraday cage (used for the cooking chamber) instead of into an antenna. I am amazed that no one has been seriously burned when trying this, since it can be quite dangerous if extreme safety measures are not used.
