Description: | LMP 220j(spurious old departmental catalogue number in black felt tip pen, removed). MANU Unsigned. first quarter 20th century DES after GEISSLER,Johann,Heinrich,Wilhelm. 1855 Bonn, Germany. This is a Geissler tube in the form of a fine pipe which is bent in complicated whorls tramlines and spirals which cross and recross. Two of the spirals and the tram lines are doped with uranium (probably uranium hexachloride) which strongly fluoresces lime green. The tube is surrounded by a refillable water filled jacket that once may have contained a fluorescent dye. N.B. all gas discharge tubes emit X-rays this is because the electrons from the cathode strike the atoms of gas in the tube at high energy levels. | 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 |
