Document Type and Number:

Japanese Patent JP4471608

Kind Code:

B2

Abstract:

In an electron tube (1), an insulating tube (9) protrudes inside an envelope (2). One end of the insulating tube (9) is connected to the envelope (2). An APD (15) is provided on the other end of the insulating tube (9). A ground voltage is applied to the envelope (2) and a positive high voltage is applied to the APD (15). Photoelectrons which are emitted in response to an incident light on a photocathode (11) are converged by an electrical field in the envelope (2) and enter the APD (15). Thereafter, the incident photoelectrons are amplified and detected. Since a positive high voltage is not exposed to the envelope (2), the electron tube (1) can easily be handled and is excellent in safety.
