Ten-layer spark chamber for nuclei fission study

The ten-layer corona type spark chamber for the investigation of nucleus fission has been developed. The chamber design and the scheme of power supply are presented. There are 100 chamber sections in the duralumin case, every two of them having a common cathode. The chamber anodes present nichrome filaments of 0.1 mm in diameter, the cathods being made of stainless steel. The anode-cathode distance is 2 mm teflon serving as an insulator between them. Different operating regimes of the spark chamber are considered. When filling the chamber with pure nitrogen, the duration of the head front is 10-8 C, and its efficiency is 20%
