ABSTRACT:
A tube arrangement has a first partial tube and a second partial tube, and one fine adjustment arrangement for coaxially displacing the partial tubes with respect to one another. The partial tubes, an aperture ring with a small aperture opening, a beta radiator point source and a GM-counter are coaxially arranged. The partial tubes are connected each with one or two of the following: an aperture ring, the beta radiator point source, and the GM-counter. A blocking means blocks the fine adjustment arrangement. One of the partial tubes is connected galvanically conducting with the GM-counter anode and the other partial tubes are connected galvanically conducting with the GM-counter cathode.
