Abstract
959,236. Ion sources. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 25, 1963 [Jan. 30, 1962], No. 3534/62. Heading H1D. A mass spectrometer ion source comprises an evacuable ion-generating chamber 41 into which particles enter, e.g. at 7, and an electrongenerating chamber 15 which may be evacuated independently of the ion chamber, and which is connected to the ion chamber by a narrow channel 18, giving a beam of electrons which bombard and ionize the particles. The electron beam may be further collimated by a magnetic field between polepieces 23, 24, adjusted by means of the soft ion discs 27 and 28. The electron beam is absorbed in the disc 28. Electrodes 31-37 accelerate the charged particles through the aperture 48 in the collimating plate. This arrangement, particularly suitable for examining free radicles formed in the chamber 6, reduces contamination from break-down products of the initial particles. An electron energy filter may be incorporated between the electron gun 15 and the channel 18.
