Popis: This work describes the development of the production of the crystal cesium iodide doped with thallium [CsI :Tl] for use as a radiation detector. For salt purification, zonal refining in a horizontal oven at a constant temperature of 700°C was used. The high temperature region corresponds to approximately 10% of the bed containing the salt (26 centimeters), this region moves with a speed of 5cm/h. The Bridgman technique was used for crystal growth, using a vertical oven whose speed is 1mm/h.
