| Abstract: | Two pieces of high position resolution parallel plate avalanchechambers(PPAC), the sensitive area of which are 100mm×100mm and 150mm×150mm have been developed. They are two dimension position sensitive, the length of delay line is increased. The divided cake structure , the electrode of strided side fetching out mode, the delay line of strided side connecting mode and directly envelopping vacuum technology in atmosphere are used. The PPACs have been tested in flowing positive heptane gas at pressure of 420Pa using 252Cf source. The position resolution of Δx=Δy=1mm has obtained |
