Abstract
A streak apparatus includes: a vacuum container 10 having an electron beam source 20 provided on one end side to emit an electron beam E and an output section 60 provided on the other end side to convert the electron beam into an image; an accelerating section 30 provided in the vacuum container to accelerate the electron beam; an irradiation optical system 40 for collecting and applying to-be-measured light R to the electron beam accelerated by the accelerating section; and a sweep section 50 provided between the accelerating section and the output section to sweep the electron beam having interacted with the to-be-measured light in a direction approximately perpendicular to the direction of a displacement of the electron beam generated through the interaction. This allows the streak apparatus to have a higher temporal resolution.
Claims10
A streak apparatus comprising:
- a vacuum container having an electron beam source provided on one end side to emit an electron beam and an output section provided on the other end side to convert the electron beam emitted from the electron beam source into an image;
- an accelerating section provided in the vacuum container to accelerate the electron beam emitted from the electron beam source;
- an irradiation optical system for collecting and applying to-be-measured light to the electron beam accelerated by the accelerating section;
- and
- a sweep section provided between the accelerating section and the output section in the vacuum container to sweep the electron beam having interacted with the to-be-measured light in a direction approximately perpendicular to the direction of a displacement of the electron beam generated through the interaction.
