Thyratron Switch Auto Ranging

reference paper [9]

It is very important to maintain proper operating internal gas pressure
to avoid abnormal operation of thyratron switches.
However, it is not so easy to maintain the pressure and thus we regularly adjust the pressure manually.
In an accelerator system where many such switches are operating,
it becomes difficult to adjust individual switch pressure.
Therefore, a method was developed to range the thyratron internal pressure automatically.
