Description: | none MANU unsigned circa 1947 DES after GEIGER,Hans,Wilhelm,Professor and MULLER,Walther. 1928 Keil University Germany This is a prototype variation of the Maze type gas proportional Geiger-Muller counting tube. It has aquadag as the cathode in the form of a coating on the outside of the tube. The anode is a tungsten filament which ran the length of the glass tube. It was supported by its lead in wire at one end and probably by a spring tensioner at the other. This tube has pumping stems at either end and was probably intended as a test bed for various gas mixtures. The operating voltage would have been variable depending on the gas mix. The purpose of the four bubble windows is unknown since they do not appear to be thin enough for alpha particle transmission. See "Counting Tubes Theory and Applications", S.C. Curran and J.D. Craggs,1949. Also J.T. Lloyd, J. sci. Instrum., 26, 1949, p. 126. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
