Title:
CHARGED PARTICLE COUNTING APPARATUS, FABRICATION METHOD THEREFOR, AND CHARGED PARTICLE COUNTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/219063
Kind Code:
A1
Abstract:
A charged particle counting apparatus, preparation method therefor, and a charged particle counting system, relating to the field of charged particle measurement. The apparatus comprises: a bipolar transistor (10) and a magneto-electric induction coil (20); a gate (101) of the bipolar transistor (10) is electrically connected to one end of the magneto-electric induction coil (20), while a constant voltage is loaded at the other end of the magneto-electric induction coil (20); when a flow of positively charged particles passes through the magneto-electric induction coil (20) and a first induced voltage produced by the magneto-electric induction coil (20) is greater than a preset voltage threshold, a channel of the bipolar transistor (10) is an N-type channel; and when a flow of negatively charged particles passes through the magneto-electric induction coil (20) and a second induced voltage produced by the magneto-electric induction coil (20) is less than a preset voltage threshold, a channel of the bipolar transistor (10) is a P-type channel. The present apparatus solves the problem of a charged particle counting apparatus having singular functionality, and is used for counting charged particles.
