Abstract
931,044. Ion sources. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 29, 1962 [March 30, 1961], No. 12119/62. Class 39 (1). In a high-frequency ion source the highfrequency excitation field is modulated to produce a pulsed beam. The electrode 9 is an electron-emitting cathode and electrode 10, the ion extraction electrode; the high-frequency field produced by conductors 12, 13 increases the probability of ionization. The conductors 22, 23 are connected across the inductance 19 in the circuit of a double-tetrode oscillator valve 18. Blocking pulses are supplied to the screen electrodes 25, 26 by a modulating valve 24 whose control grid 29 is connected to a pulse generator 30. The generator 30 supplies pulses of variable length and frequency. The pulse generator 30 may be a monostable multivibrator, the flip-flop action of which is produced by a second multivibrator.
