Abstract
【解決手段】ガイガーモードで動作する複数のアバランシェフォトダイオードと、各アバランシェフォトダイオードに対して直列に接続されたクエンチング抵抗と、を備えているフォトダイオードアレイに逆バイアス電圧を印加する。印加する逆バイアス電圧を変化させて電流を測定し、測定した電流の変化における変曲点での逆バイアス電圧を基準電圧として決定する。決定された基準電圧に所定の値を加えて得た電圧を推奨動作電圧として決定する。
【選択図】図5
Description
M=C×ΔV
Cは、各アバランシェフォトダイオードの接合容量である。ΔVは、最も多くのアバランシェフォトダイオードがガイガーモードに移行する逆バイアス電圧、すなわち基準電圧からの電位差である。したがって、推奨動作電圧と基準電圧との差が決まれば、増倍率Mが一意的に決まることとなる。逆に、所望の増倍率Mを得るためには、基準電圧に上記関係式を満たすΔVを加えればよい。
