Title:
ION-OPTICAL SYSTEM FOR GAS-DISCHARGE ION SOURCE
Document Type and Number:
WIPO Patent Application WO/1994/005032
Kind Code:
A1
Abstract:
An ion-optical system of a gas-discharge ion source comprises an emitter electrode (1) and an accelerating electrode (2) consisting of frames (3, 4) and of a system of parallel wires (5, 6) attached to said frames by means of springs (21), and a device (19) for adjustable movement of the wires in each of the electrodes. A device (9) comprises rollers (11) oriented perpendicularly to the wires and provided with guiding elements (12) receiving said wires. The rollers (11) in each of the electrodes (1 and 2) are mounted on the frames (3, 4) and can rotate about their axes and change their spacial position together with the wires. This allows the wires to be fixed in each of the electrodes with a desired spacing in an axially parallel position which allows the stability of functioning of the ion source to be increased.
