Abstract
The present invention relates to a microstrip gas chamber and microstrip plate capable of reading signals from readout electrodes provided at a rear surface of the substrate in a superior manner while having a simple and compact configuration. The microstrip plate comprises an electrically insulating substrate 1, cathodes 2 and anodes 3 arranged alternately at the surface of the substrate 1, read-out electrodes 4 arranged so as to intersect the cathodes 2 and anodes 3 at the rear surface of the substrate 1, wherein a plurality of unitary regions 20 are provided at the surface of the substrate 1 and each unitary region 20 is electrically floated from the cathode via a resistance region 5.
