Title:
ＣＥＭアセンブリおよび電子増倍デバイス
Document Type and Number:
Japanese Patent JP7176927
Kind Code:
B2
Abstract:
According to an embodiment, in a CEM assembly and the like, it is possible to reduce a size of a voltage supply circuit configured to stabilize a voltage to be applied to a channel electron multiplier. The CEM assembly includes a CEM and a voltage supply circuit. The CEM includes an input electrode, a multiplication channel, and an output electrode. The voltage supply circuit includes a power source unit and a constant voltage generation unit. A potential of an input electrode A is set by an electromotive force generated by the power source unit. The constant voltage generation unit includes a constant voltage supply unit configured to cause voltage drop. A target potential set at an output-side reference node is maintained by the voltage drop of the constant voltage supply unit.
