B. M. Ovchinnikov, V. V. Parusov, Yu. B. Ovchinnikov

摘要:

提出了金属电极多通道气体电子倍增器(MGEM)的设计方案,并进行了实验研究。MGEM的电极由厚度为1 mm的黄铜板制成,直径为1 mm的圆形开口,它们之间的台阶为1.5 mm。电极间距为3mm,工作区直径为20mm。当(H_2O+N_2)<100ppm时,氖的电子比例倍增系数最大值为30000。

英文摘要:

The design of multi-channel gas electron multiplier (MGEM) with metallic electrodes is proposed, produced and tested. The electrodes of MGEM are produced from the brass plates with thickness of 1 mm, round openings of 1 mm in diameter and 1.5 mm steps between them. The gap between the electrodes is equal to 3 mm, while the total working area has a diameter of 20 mm. The neon gas fillings of the MWGEM chamber with micro admixtures of N_2 and H_2O have been tested. The total maximal coefficient of proportional multiplication of electrons in neon with admixture of (H_2O+N_2)<100 ppm of 30000 is obtained.
