    摘要: Sufficient dielectric strength needs to be ensured for the high voltage connection (13-11) of the high voltage electrical equipment such as a pattern generation system for focused ion beam processing and observation (1), without enlarging the equipment.
    The present invention seals an insulating liquid (13-113a) or gas (13-113b) in the space (13-113) between the connection bushing on the power supply side (13-111) and the flange on the power receiving side (13-112), and applies the water repellent treatment (13-111c) to a surface of the connection bushing or flange on the power receiving side, which the surface faces the space (13-113).
    Such a configuration provides compact electrical equipment with high dielectric strength, which can prevent the condensation or moisture absorption on the insulation surface in the space of the high voltage connection and can prevent the leakage current increase even under high humidity environment.

    摘要: In a charged particle beam device, comprising a charged particle source (9) for emitting a charged particle beam, a column comprising particle-optical elements which are enclosed by a column jacket (10) and which serve to accelerate and focus the charged particle beam, the charged particle source comprising an emitter (11) which is accommodated in an emitter chamber (19), a vibration-insensitive suspension of the emitter is achieved by connecting the emitter chamber to the column jacket via a tubular electrode system (25). Because the pumping device (39) cooperating with the emitter chamber is arranged above the emitter chamber and in the prolongation of the column, disturbing effects of the pumping device on the emitter are reduced. Because the power supply unit (47) is arranged in the vicinity of the emitter, high-voltage supply leads can be dispensed with, so that interference signals cannot reach the emitter via the supply leads. The use of optical communication via optical fibres (51) prevents the occurrence of undesirable potentials in the equipment.

    摘要: An improvement in high power electron beam guns including a non-inductive high-voltage cable (24-3C) for supplying power to the gun (1) having barriers for preventing air leakage from inside the cable into the vacuum chamber. The gun (1) includes a support for its cathode (2) and filament, which transmits heat developed in these elements to a heat sink so that dimensional accuracy is maintained in the electron beam generating elements. Provision is made for quick release of cable terminations from the gun (1) receptacle and for maintaining a given pressure in insulating grease placed between mating surfaces of plugs and receptacles.

    摘要: It is necessary to secure a sufficient dielectric strength without increasing the size as a high-voltage apparatus in high-voltage connecting sections (13-11) of a high-voltage electric apparatus such as an ion beam processing observation pattern generator (1). An insulating liquid (13-113a) or a gas (13-113b) is encapsulated into a gap (13-113) between a power-feed side connection bushing (13-111) and a power-receiving side flange (13-112), and the connection bushing facing the gap (13-113) or the power-receiving side flange are treated by water repellent finishing (13-111c) in their surfaces. This constitution provides a small-sized electric apparatus of high dielectric strength for suppressing dew condensation or humidity absorption in the insulating surface in the gap in the high-voltage connecting section and for suppressing an increase in leakage current under a high-humidity environment.

    摘要: An arc suppressor is provided for an electron gun of the type used e.g. in semiconductor lithography equipment. The arc suppressor prevents damaging emission properties of the electron gun either due to variation of the cathode work function or any damage to the emitter apex. The arc suppressor includes a resistance and an inductor in series with each electrode lead providing voltage or current to the various electrodes of the electron gun. The inductance is provided by a ferrite toroid which contains a plurality of holes in addition to the main central hole. The leads for each electrode are wrapped around the toroid through the various holes, with one hole being provided for each lead. Thus advantageously each lead is isolated magnetically from the others, reducing the transformer and capacitive effects that couple one lead to another.
