号選択装置。 The detector selection switch and the switch that connects and disconnects the scintillator to the high-voltage power supply H are interlocked, the signal output terminal of the photomultiplier tube for electron detection is connected to the two fixed contacts of the detector selection switch, and the selection switch is connected. When the switching piece is brought into contact with one of these two fixed contacts, the above-mentioned contact/disengagement switch is turned on,
When the switching piece of the selection switch comes into contact with another fixed contact, the above-mentioned contact/separation switch is turned OFF, and a sample current detector is provided, and when the output of the detector exceeds a certain level, the selection switch is turned off. A signal selection device characterized in that a locking means L is provided to prevent the switching piece from coming into contact with one of the two fixed contacts.
