离子检测装置
摘要：
本发明的离子检测装置(1)，具备设置有使正离子以及负离子进入的离子进入口(3)的腔室(2)、配置于腔室(2)内并被施加负电位的转换倍增极(8)、配置于腔室(2)内并具有与转换倍增极(8)相对并且入射从转换倍增极(8)释放的二次电子的电子入射面(11a)的闪烁器(11)、形成于电子入射面(11a)并被施加正电位的导电层(13)、以及检测对应于二次电子的入射而由闪烁器(11)发出的光的光电倍增管(15)。
摘要（英）：

An ion detector for detecting positive ions and negative ions, includes a housing provided with an ion entrance to make the positive ions and the negative ions enter, a conversion dynode which is disposed in the housing and to which a negative potential is applied, a scintillator which is disposed in the housing and has an electron incident surface which is opposed to the conversion dynode and into which secondary electrons emitted from the conversion dynode are made incident, a conductive layer which is formed on the electron incident surface and to which a positive potential is applied, and a photodetector which detects light emitted by the scintillator in response to incidence of the secondary electrons.
