Abstract:
An emitter ( 3 ) and a target ( 7 ) are arranged so as to face each other in a vacuum chamber ( 1 ), and a guard electrode ( 5 ) is provided at an outer circumferential side of an electron generating portion ( 31 ) of the emitter ( 3 ). The emitter ( 3 ) is supported movably in both end directions of the vacuum chamber ( 1 ) by the emitter supporting unit ( 4 ) having a movable body ( 40 ). The emitter supporting unit ( 4 ) is operated by an operating unit ( 6 ) connected to the emitter supporting unit ( 4 ). By operating the emitter supporting unit ( 4 ) by the operating unit ( 6 ), a distance between the electron generating portion ( 31 ) of the emitter ( 3 ) and the target ( 7 ) is changed, and a position of the emitter ( 3 ) is fixed at an arbitrary distance, then field emission is performed with the position of the emitter ( 3 ) fixed.

Claim (Index 13):
An electric field radiation device comprising:\n a vacuum enclosure formed by sealing both end sides of a tubular insulator and having a vacuum chamber at an inner wall side of the insulator; an emitter positioned at one end side of the vacuum chamber and having an electron generating portion that faces to the other end side of the vacuum chamber; a guard electrode arranged at an outer circumferential side of the electron generating portion of the emitter; a target positioned at the other end side of the vacuum chamber and provided so as to face to the electron generating portion of the emitter; a movable emitter supporting unit supporting the emitter movably in both end directions of the vacuum chamber; and an operating unit connected to the emitter supporting unit and operating the emitter supporting unit, and the operating unit being configured to change a distance between the electron generating portion of the emitter and the target and fix a position of the emitter at an arbitrary distance by operation of the emitter supporting unit by the operating unit, the guard electrode being provided, at a target side thereof, with a small diameter portion which the electron generating portion of the emitter contacts and separates from, and field emission being performed by the electron generating portion of the emitter with the position of the emitter fixed.
