GAMMA RAY SPECTROMETER DISPLAY MEANS

A gamma ray spectrometer having a plurality of presettable channels, a given channel being selectable for displaying on a cathode ray tube a trace proportional to the energy of the gamma ray of a given sample and the intensity of the given energy event. The cathode ray tube is originally biased so t...

Beschreibung
Zusammenfassung:	A gamma ray spectrometer having a plurality of presettable channels, a given channel being selectable for displaying on a cathode ray tube a trace proportional to the energy of the gamma ray of a given sample and the intensity of the given energy event. The cathode ray tube is originally biased so that the beam is below the face of the tube and therefore not displayed. A sweep gate signal for the cathode ray tube is driven by the selected channel for deflecting the beam onto the face of the tube and for selectively blanking and unblanking the cathode ray tube in response to the sweep gate signal for displaying on the cathode ray tube only that trace indicative of the selected channel, the height of the trace on the tube being indicative of the energy while the intensity of the trace so displayed is proportional to the count rate.
