WebThe treatment head of prot otype medical linac machine has been designed with tungsten as a target material. The optimized thickness of tungsten is 2.682 mm with a 3 mm beryllium as an electron stopping material. This configu ration provides an optimized dose rate and a low electron leakage rate of 0.05%. The concept of using double layer WebThe reason for this is probably a corrosion effect of the conductive plates in the chamber due to the increased relative humidity during hot periods. We have found that the responses of the different ion chamber plates change with variations in air humidity and that they do not return to their original values when the air humidity is returned to ambient conditions.
