Abstract
A particle detector for detecting a particle beam includes a negatively charged electrode plate having a first side facing the particle beam, a second side opposite to the first side, and a through-hole extending from the first side to the second side for receiving the particle beam. A detection device adjacent to the second side of the electrode plate detects signals corresponding to the particle beam approaching the through-hole.
