Title:
IMPROVEMENTS IN PHOTOMULTIPLIER TUBE
Document Type and Number:
Japanese Patent JP2022103330
Kind Code:
A
Abstract:
To provide a device for amplifying an electronic signal generated by collision of particles with an electron emitting surface.SOLUTION: A device includes: a first electron emission surface configured to receive input particles and thereby emit one or more secondary electrons; a series of second electron emission surfaces and subsequent electron emission surfaces configured to form an amplified electron signal from one or more secondary electrons emitted by the first electron emission surface; and one or more power supplies configured to apply a bias voltage sufficient to form the electronic signal to be amplified to one or more emission planes. The device is configured such that electron emission surfaces at the end of the series of second electron emission surfaces and subsequent electron emission surfaces draw a current higher than the current of the remaining electron emission surfaces. The device may be used, for example, as part of a detector in a large-scale spectrometer.SELECTED DRAWING: Figure 3A
