A plurality of positioning parts are provided between an outer surface of the electron discharge unit and an inner surface of the unit accommodation part, the positioning parts being slidably in contact with an outer surface of the electron discharge unit or an inner surface of the unit accommodation part and performing positioning of the electron discharge part with respect to the unit accommodation part.

A vacuum container is configured so that an opening on one side and an opening on another side in the longitudinal direction of a cylindrical insulating body are sealed with an emitter unit and a target unit respectively; and a vacuum chamber is provided on the inner peripheral side of the insulating body. The emitter unit is provided with: a moving body located on the one side in the longitudinal direction in the vacuum chamber and supported so as to be movable in the longitudinal direction via a bellows; and a guard electrode located on the outer peripheral side of the moving body. An emitter section having an electron generating section is formed at a tip section of the moving body on the other side in the longitudinal direction by subjecting the surface of the tip section to film formation processing.

An apparatus includes: a structure having a lumen for accommodating a beam, wherein the structure is a component of a medical radiation machine having a target for interaction with the beam to generate radiation; and a first beam position monitor comprising a first electrode and a second electrode, the first electrode being mounted to a first side of the structure, the second electrode being mounted to a second side of the structure, the second side being opposite from the first side; wherein the first beam position monitor is located upstream with respect to the target.

Provided is a photocathode kit that does not require adjustment of the distance between a photocathode film and a lens focusing on the photocathode film when the photocathode and the lens are installed inside an electron gun. The photocathode kit includes: a photocathode including a substrate in which a photocathode film is formed on a first surface; a lens; and a holder that holds the substrate and the lens, and the holder has a retaining member that retains the photocathode film and the lens to be spaced apart by a predetermined distance, and a first communication path that communicates between inside of the holder and outside of the holder.

In some embodiments, an electrical device can include a body having a shape that extends along a longitudinal direction, and a set of electrodes implemented on the body at different locations along the longitudinal direction and configured to allow the electrical device to be positioned and mounted to a surface. The set of electrodes can include first and second electrodes configured to provide first and second engagements with the surface, respectively, and to allow a settling motion when the electrical device is positioned on the surface. The set of electrodes can further include a selected electrode having a side configured to allow the settling motion and an engagement portion configured to stop the settling motion and thereby provide a third engagement with the surface.
