Abstract

1450320 Ion sources HEWLETT-PACKARD CO 9 Aug 1974 [27 Aug 1973] 35218/74 Heading H1D An ion source operable in two modes in which the gas to be ionised is at different pressures comprises within an evacuable enclosure 14 a chamber 16 having a slidable hollow member 28 within a bore 24. With the member 28 in the position shown gas is admitted through an orifice (23) Fig. 2 (not shown) in chamber 16 and an inlet 20 in member 28 while electrons from a filament 18 in orifice 17 pass through passage 32 in member 28 towards a collector 50 under the action of magnets 52, 52<SP>1</SP>. In this mode ions are emitted through conical passage 34 in an insert 35 in member 28. An ion repelling potential is applied via a connector 38 to insert 36 also in member 28. In the second mode, Fig. 2, the member 28 is moved to the left by means of arm 72 and handle 48, the vacuum being maintained by bellows 46, to the extent that insert 35 is to the left of orifice 17 with the effect of increasing the aperture through which the electrons enter the ionisation region and the aperture by which the ions are emitted, thus lowering the pressure of the ionised gas. In this case the repelling voltage is applied to insert 35. Reference has been directed by the Comptroller to Specification 1338213.
