Abstract: 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.

Abstract: Gamma ray measuring apparatus having a multi-compartment sample holder incrementally advanced along the surface to a measuring station. The sample holder contains a plurality of sample containing vials in close mating relationship within the compartments, each compartment being provided with an aperture in the bottom thereof, the aperture being of smaller dimension than the cross-sectional dimension of the vial. A detector assembly at the measuring station has an elongated access port therein, the lower portion of the access port having a funnel-shaped entrance end with the upper portion thereof having a crystal detector in proximity thereto. An elevating rod passes through the aperture engaging the bottom surface of the vial to raise the vial guided by the compartment and the funnel-shaped entrance through the access port into the sample chamber adjacent the crystal detector for sample measurement. The elevating rod is made of a shielding material for shielding the crystal detector from rays emanating from samples within the sample holder. Provision is made for access to the well by means of a manual sample access port in alignment with the upper portion of the well. The port is plugged during operation of the apparatus in the automatic mode, and a special vial holder is provided for access to the well in a manual mode.
