Characteristics of a Parallel Plate Avalanche Counter with Thin-Film Electrodes
A small parallel plate avalanche counter (PPAC) consisting of a 0.2 µm-thick stretched polypropylene film was fabricated. Its characteristics as a time-sensitive detector were examined with α-particles from an 241 Am source, and a time resolution of 150 psec was obtained. The pulse height distributi...

| Zusammenfassung: | A small parallel plate avalanche counter (PPAC) consisting of a 0.2 µm-thick stretched polypropylene film was fabricated. Its characteristics as a time-sensitive detector were examined with α-particles from an
241
Am source, and a time resolution of 150 psec was obtained. The pulse height distribution of the avalanche electrons was observed and the cause of the distribution was studied. The distribution could be explained as a result of two kinds of fluctuation resulting from energy loss and electron avalanche multiplication. |
