WebThis problem has been solved! In an experiment using a gamma spectrometer, which is a cylindrical crystal NaI (Tl) detector, the Cs-137 isotope with a current activity of 8.6 μCi was placed at a distance of 3 cm from the detector and a 500s count was taken. The net photopic count was found to be 2504535 at 662 keV energy in the received spectrum. WebSep 19, 2024 · The crystal diameter is in the state of labile equilibrium during the Czochralski process. For automatic diameter control of high-temperature oxide crystals, the weight of the crucible is continuously monitored with high precision and electronically compared with a programmed weight decrease for growing a cylindrical crystal.
