External photon effect detector - external photon effect detector

…A photoelectric detector that is sensitive to the wavelength range of 10 to 380 nm. Because the photon energy is large, external photon effect detectors with a metal photocathode are often used, as well as photomultiplier tubes with an ultraviolet-visible conversion phosphor such as sodium salicylate on the front. The wavelength range shorter than 200 nm is called the extreme ultraviolet range, and various detectors with unique characteristics are used in the wavelength range from 120 nm onwards. …

*Some of the terminology used to refer to "external photon effect detectors" is listed below.

…光検出器の中でも10～380nmの波長領域に感度をもつ光電検出器をいう。光子エネルギーが大きいため金属光電面をもつ外部光子効果型検出器をはじめ，サリチル酸ソーダなどの紫外‐可視変換蛍光体を前面にもつ光電子増倍管がよく用いられる。とくに200nmより短波長側は極紫外域と呼ばれ，なかでも120nmから短波長側では特徴のある種々の検出器が用いられる。…
