  • The authors study the operation of the Gas Electron Multiplier (GEM) is pure Ar, in comparison to that in Ar-CO{sub 2} mixture. In pure Ar, high GEM gains, of above 700 and 3000 for single and double GEM structures correspondingly, have been obtained. It is observed that the GEM effective gain and its charging-up are strongly affected by electric field values above and below the GEM. Applications to the development of non-aging gas photomultiplier are discussed.
  • A lot of effort has been invested in the development of the Microstrip Gas Chamber (MSGC) to be used as tracker for the LHC project. This technique allows good localization accuracy and double track resolution. However, it is necessary to operate it with a relatively low gas gain because of the presence of the insulator near the amplification region and the fragility of the structure. Recently, a new preamplification structure called GEM has been introduced, which can give additional gas gain and compensates for the lack of gain in the original MSGC. Other concepts of novel proportional counters have beenmore » recently proposed: CAT and MICRO-DOT. A review of recently developed gaseous detectors is provided. MICROMEGAS is a high-gain gaseous detector, which is a stand-alone detector without a need for additional preamplification. It combines high accuracy, high-rate capability, excellent timing properties, and robustness. These results were confirmed by a similar structure having a wider amplification gap and a thicker metallic grid.« less
  • Cosmic ray experiments outside the Earth's atmosphere are subject to severe restrictions on the mass of the instruments. Therefore, it is important that the experimental information that can be obtained per unit detector mass is maximized. In this paper, tests are described of a thin (1.4 {lambda}{sub int}deep) hadron calorimeter that was designed with this goal in mind. This detector was equipped with two independent active media, which provided complementary information on the showering hadrons. It is shown that by combining the information from these media it was possible to reduce the effects of the dominant leakage fluctuations on themore » calorimeter performance.« less
