为寻找宇宙线中的长寿命重电离粒子,1981年我们用醋酸纤维素(CA,140μm厚)和Makrofol-E(西德产,300μm厚)组装成探测器(4.05m~2),放置在海拔5500m的甘巴拉山上,1982年已回收。CA和Makrofol-E有多种蚀刻条件,有必要从中找出适于大面积蚀刻的条件,这对于我们今后在宇宙线研究中,大面积使用CA和Makrofol-E是有益的。对宇宙线中重离子蚀刻条件的选择需要考虑的因素较多,本工作仅在探测器灵敏度方面初步作了一些
In 1981, we assembled detectors (4.05 m ~ 2) with cellulose acetate (CA, 140 μm thick) and Makrofol-E (West Germany, 300 μm thick) to locate the long- Mt. Kanbarra at 5500m above sea level was recovered in 1982. There are many etching conditions for CA and Makrofol-E, and it is necessary to find out the conditions suitable for large-area etching. This is beneficial for the future large-scale use of CA and Makrofol-E in cosmic ray research. There are many factors to be considered in the selection of heavy ion etching conditions in the cosmic ray. Some preliminary work has been done on the sensitivity of the detector
