Abstract
PURPOSE: To simplify the measurement of a dark current by finding the dark current by measuring a current value when an anode current obtained by radiating hot electrons from a cathode is provided with a magnetic field or an anode voltage value when the current value is held constant.
CONSTITUTION: Anode cylinder 1 is internally equipped with a cathode, vein, etc., and inside of it, a vacuum is produced to constitute a magnetron. Under and over anode cylinder 1, permanent magnets 4 of "N" and "S" are fixed so as to provide a magnetic field inside and outside of anode cylinder 1. For measurement, switches S1 and S2 are both turned ON with the magnetic field provided inside of anode cylinder 1. At this time, anode current Ii by hot electrons from a cathod in anode cylinder 1 or anode voltage Ei when constant Ii is set is indicated by meter 6. This value is read and then related to a characteristic curve between Ii or Ei and dark current Ib, so that dark current Ib of the magnetron can easily be measured.
