Abstract
A new glass capillary plate (CP) has been developed for a hole-type micro-pattern gas detector (MPGD). The developed CP has a funnel structure (funnel-CP) fabricated using a special manufacturing process for a CP. The opening to surface area ratio is 83% for the funnel-CP. A higher ratio is expected to improve the collection efficiency of primary electrons created by X-ray radiations, a higher optical transparency should prove reliable for digital X-ray radiography and cold neutron imaging. Basic performance tests of the hole-type MPGD were carried out using X-ray beams for several gas mixtures based on neon and argon at 1Â atm. We successfully obtained a gain of up to 1Ã104, and an energy resolution of 16% for 6Â keV X-rays. An excellent imaging capability was demonstrated by the X-ray image.
