Title:
電子線検出装置及び電子管
Document Type and Number:
Japanese Patent JP4424950
Kind Code:
B2
Abstract:
An insulating tube (9) has one end and another end. An APD (15) is provided outside the one end of the insulating tube (9). The another end of the insulating tube (9) is air-tightly connected to an outer flange (120) through a stem inner wall (61). Capacitors (C1, C2) electrically connected to the APD (15) are provided in the insulating tube (9). The capacitors (C1, C2) remove direct current components from signals that the APD (15) generates when detecting electrons.' By providing the capacitors (C1, C2) in the insulating tube (9), response of output signals can be prevented from being impaired.
