THIN FILM TRANSMISSION MULTIPLIER
Technical Report
·
OSTI ID:4842754
A transmission multiplier is described in which electrons release secondaries from the back of a very thin dynode of special construction. Its application as a mass spectrometer detector is discussed. The films used were of evaporated potassium chloride on gold on a film of VYNS. Nine stages were used to give high gain, but the electron beam spread laterally from one dynode to the next. Attempts to overcome this with an applied magnetic field were unsuccessful. Thus simultaneous detection of several masses with single ion detection sensitivity did not prove to be practicable with this device. (auth)
