Abstract
The present invention addresses the problem of providing an electron beam generator and an electron beam applicator for which maintenance is facilitated. The electron beam generator comprises a vacuum chamber, a photocathode holder, an activation vessel, and an internal motive power transmission member. The photocathode holder is capable of moving relative to the activation vessel.
Claims20
An electron beam generator comprising:
- a vacuum chamber;
- a photocathode holder disposed inside the vacuum chamber and supporting a photocathode material;
- an activation vessel disposed inside the vacuum chamber and supporting a surface treatment material that lowers electron affinity of the photocathode material;
- and
- an internal motive power transmission member that is disposed inside the vacuum chamber and that transmits drive force to the photocathode holder or the activation vessel;
- the photocathode holder being capable of moving relative to the activation vessel,
- wherein the internal motive power transmission member is disposed in a vacuum area inside the vacuum chamber and is configured to be driven in the vacuum area only with energy generated from outside the vacuum chamber.
