Performance study of a micro-pattern gas detector： leak microstructure

A micro-pattern gas detector named leak microstructure （LM） has been studied. A new chemical electrolytic technique is introduced to make perfect shaped LM needles with very sharp tips, and this method may be developed to make LM array detectors in batches. The experimental results are presented for...

description	A micro-pattern gas detector named leak microstructure （LM） has been studied. A new chemical electrolytic technique is introduced to make perfect shaped LM needles with very sharp tips, and this method may be developed to make LM array detectors in batches. The experimental results are presented for both a single needle LM detector and a small LM array detector. The gas gain is up to 105 by calculation from the waveform. Good gain stability and uniformity are achieved. The light emission from the needle tip is also measured in Ar/CF4 （95/5） gas mixture. The result shows a promising application for imaging.
