reverse/min power

Would you kindly obfuscate your question a little better. I almost have an idea what you are talking about. If you completely obliterated any meaning to your question I could then make any oblique comment and honestly claim that it was relevant to the question.

Now it can be very expensive installing a high power isolator to the output of a 40 megawatt RF amplifier for a circular particle accelerator. However, when the timing of the RF pulse is OFF in comparison to the bunches of charged particles entering the drift chamber the reflected power can do considerable damage to the RF tube. This isolator can certainly be cheaper than frequently replacing the power tube.
