Model of the Russian made Geiger-Müller tube SBT-11( СБТ-11 )

I have created this 1:1 scale model as an aid for designing things containing this excellent Russian-made Geiger-Müller tube. English translation of specifications of this tube are here:

This looks to be one of the tubes which has the thinnest mica window and can be used for detecting alpha particles. See the bottom of this article (choose google translation to English in the dropdown box below the menu on the left): www.ligis.ru/tech_67.htm

If you found my design useful or inspiring and would like to buy me a cup of espresso you are welcome to tip me:
