Description: 
In the late 1940's and early 1950's, Yu. G. Shafer constructed, at 
the Laboratory of Cosmic Rays in Yakutsk, the ASK-I ionization chamber which 
automatically and continuously records the intensity of the flow of cosmic 
rays. Another installation, designed by D. D. Krasil'nikov, registers 
showers of cosmic rays. A workshop of the Laboratory is located at a depth

by A. I. Kuz'min, continuous investigations on changes in the flow of under- 
ground cosmic rays are conducted.
