Abstract
A light source has a discharge vessel which is filled with a filling gas, and an electron beam source which is arranged in vacuum or in a region of low pressure. The electron beam source generates electrons which are propelled through an entry foil into the discharge vessel. An electric field may be generated inside the discharge vessel.
Claims22
A light source comprising:
- a discharge vessel which is filled with a filling gas,
- an electron beam source arranged in vacuum or in a region of low pressure, wherein said electron beam source is configured to generate and propel electrons through an inlet foil into the discharge vessel,
- a pair of electrodes located at sides of the discharge vessel adjacent to the inlet foil, wherein at least one of the electrode is a coil configured to generate an inductive AC field in the discharge vessel, and
- an electric field generator configured to generate an electric field inside the discharge vessel between the pair of electrodes.
