Advantages of BT-258
– Working voltage is more than two times less in comparison with analogues, which leads to a simplification of the power supply and reduction of harmful X-rays during operation.
– Ability to work in air, without an oil tank, which reduces the weight of the whole installation.
– Absence of the solenoid, permanent magnet operation, that reduces the weight of the klystron and increases efficiency of the plant due to the absence of solenoid power losses.
