Title:
FIELD EMISSION DEVICE AND FIELD EMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/221479
Kind Code:
A1
Abstract:
An emitter (3) and a target (7) are arranged oppositely in a vacuum chamber (1), and a guard electrode (5) is provided on the outer peripheral side of the electron generating unit (31) of the emitter (3). An emitter support unit (4), which comprises a moving body (40) which can move freely towards both ends of the vacuum chamber (1), supports the emitter (3) movably towards both ends. The emitter support unit (4) is operated by an operation unit (6), which is connected to said emitter support unit (4). The emitter support unit (4) is operated by the operation unit (6) to change the distance between the electron generating unit (31) of the emitter (3) and the target (7), the emitter (3) is positioned and fixed at an arbitrary distance, and field emission is performed in said positioned and fixed state.
