Abstract
A particle beam apparatus with a source for generating a primary particle beam, means for focussing the primary particle beam onto a specimen, a detection system for detecting particles released at the specimen, first means to accelerate the primary particle beam to a first energy, first means to decelerate the primary particle beam before the detection system from the first energy to a second lower energy, second means to accelerate the primary particle beam after the detection system from the second energy to a third higher energy and second means to decelerate the primary particle beam from the third energy to a final beam energy. The detection system further comprises a converter to convert particles released at the specimen into converted secondary particles which will be detected by the detector.
