Abstract: A system and method for cutting soluble scintillator material are disclosed. The system includes a scintillator cutting apparatus including a filament rotated around a plurality of pulleys in at least one direction and in operative proximity to the material thereby cutting the material. The system also includes a linear motion motor operatively connected to the scintillator cutting apparatus for moving the apparatus to position the filament in operative proximity and a linear motion speed sensor for sensing rate of movement of the apparatus as the apparatus is moved by the linear motion motor to position the filament in operative proximity. The system further includes a master motor controller operatively connected to the linear motion motor and the linear motion sensor, wherein the master motor controller controls the linear motion motor as a function of sensed information obtained from the linear motion speed sensor.

Abstract: The present disclosure provides methods for forging cylindrical alkali halide melt-grown single-crystal-type ingots into rectangular blocks. The resulting rectangular blocks are devoid of peripheral cracks and fissures, and possess uniform properties and reduced levels of impurities.

Abstract: A process control system for a crystal-growing apparatus is provided which includes a process controller and a temperature controller. The temperature controller includes an input terminal which receives a temperature adjustment signal from a bottom heat thermocouple indicating the melt temperature. Based on the melt temperature, the temperature controller determines whether to increase, decrease or keep constant the melt temperature. The temperature controller further includes two additional input terminals which receive pulses from a pulse generator of the process controller for automatically controlling temperature switches of a bottom heater temperature controller in accordance with the sensed level of the melt. The pulses are generated by the pulse generator upon receiving data with respect to how much the temperature needs to be adjusted and in which direction (increase or decrease).
