…In high vacuum regions, the common method is to ionize gas molecules with thermal electrons and measure the amount of ions produced as a result. This is called an ionization gauge. Those that can measure up to slightly higher pressures are called Schultz type, and those that have been improved to be usable in ultra-high vacuum regions are called B-A type. … *Some of the terminology that refers to "ionization gauge" is listed below.

…高真空領域では,熱電子によって気体分子を電離し,その結果生成したイオンの量を測るという方法が一般的である。これを電離真空計ionization gaugeという。やや高い圧力まで測定できるものをシュルツ型といい,超高真空領域まで使用できるよう改善されたものをB‐A型と呼ぶ。… ※「ionization gauge」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
