Abstract: It is a CNT device (1) (carbon-metal structure) equipped with a carbon nanotube layer (2) (CNT layer 2; same hereafter) on a metal pedestal (4). The metal pedestal (4) is brazed to the CNT layer (2) with a brazing material layer (3) interposed therebetween. When manufacturing the CNT device (1), firstly, the CNT layer (2) is formed on a heat-resistant textured substrate (6). Next, the metal pedestal (4) is brazed to the CNT layer (2) that is on the heat-resistant textured substrate (6) with the brazing material layer (3) interposed therebetween. Then, the metal pedestal (4) (and the CNT layer 2) is peeled off the heat-resistant textured substrate (6) to transfer the CNT layer (2) from the heat-resistant textured substrate (6) to the metal pedestal (4).

Abstract: Emitter (3) and target (7) are arranged so as to face each other in vacuum chamber (1), and guard electrode (5) is provided at outer circumferential side of electron generating portion (31) of emitter (3). Emitter (3) is supported movably in both end directions of vacuum chamber (1) by emitter supporting unit (4) having movable body (40). To perform regeneration process of guard electrode (5), emitter is moved to no-discharge position by operating emitter supporting unit, and state in which field emission of electron generating portion (31) is suppressed is set, then by applying voltage across guard electrode (5), discharge is repeated. After regeneration process, by operating emitter supporting unit again, emitter is moved to discharge position, and state in which field emission of electron generating portion (31) is possible is set with movement of movable body (40) toward the other end side being restrained by movement restraining unit (6).

Abstract: In a vacuum chamber (1), an emitter (3) and a target (7) are opposed to each other. A guard electrode (5) is disposed around an outer circumference of an electron generating portion (31) of the emitter (3). A supporting part (4) supports the emitter (3) movably in an end-to-end direction of the vacuum chamber (1). Reforming treatment is performed on the guard electrode (5) by operating the supporting part (4), moving the emitter (3) to an open end (21) side (non-discharge position) and applying a voltage to repeatedly effect discharge on the guard electrode (5) in a state where field emission from the electron generation portion (31) is suppressed. After the reforming treatment, the supporting part (4) is again operated. The emitter (3) is moved to an open end (22) side (discharge position) and placed in a state where field emission from the electron generation portion (31) is allowed.
