Description: | Model of 11 stage photomultiplier, made by the staff of Centronic Ltd in 1956 and presented to Mr G Tomes (the founder of the company). The operation of the photomultiplier was based upon the emission of electrons from matter by electromagnetic radiation of certain specified energies. Photomultipliers are often used in scintillation counters, which measure the activity of a radiation source. | License: | http://creativecommons.org/licenses/by-nc-sa/2.5/ | Subjects: | Photomultiplier | Temporal: | 1956 | Source: | Science Museum | Creator: | 20th Century Electronics Ltd | Identifier: | 2000-1502 | Go to resource |
