AN AUTOMATIC RECORDING $gamma$-SPECTROGRAPH
Gamma spectrographs having high identification capabilities, are widely used for measuring gamma rays in radiation chemistry. Comments on the manufacture of the automatic recording gamma s spectrographs are made. The spectrograph consists of a head, linear impulse amplifier, single channel micro impulse analyzer, timer, automatic adjusting device, dial, integrator, automatic recording device, and counting tubes. When gamma rays touch crystals, the crystals transform energy into photo-energy which, in turn, reflects it to the photo cathode which is part of the photomultiplier. The multiplier is used for recording photons from fluorescent substances and amplifying purposes, one flash will amplify to 10/sup 6/ - 10/sup 9/. The amplified impulse is then transmitted to a linear impulse amplifier and impulse analyzer. After being checked by automatic adjusting devices, the impulse is transformed into electric potential and by the means of a dial is sent to an automatic recorder. Time intervals are adjusted by a transmitter and data recorded by counting tubes. (auth)
