Body current meter 820811
Abstract
A module to control the klystron body current caused by badly focused electrons is presented. A sample and hold circuit with timers started by the current impulse frontside and selecting a time interval was developed. An upper limit adjustment with comparator, giving the alarm signal is carried out. Current and adjusted value are indicated. Automatic and external alarm resets are present. The apparatus is provided with recorder and monitor output to register and observe the current inputs. The measuring shunt, a 1 ohm resistance, is attached to the klystron body.
