Graphite calorimeters of different thickness in the range of 0.6mm to 10mm have been designed and Fabricated for the dosimetry of 2MeV electron beam accelerator. Average absorbed dose in each of the Calorimeters of different thickness has been determined. The paper report same thod for selecting calorimeters with suitable thickness for its application as absorbed dose calorimeters and as total energy absorption calorimeters for anelectron beam of particular energy. Also it reports, using Calorimeters of different thickness, it is possible to estimate various parameters such as energy fluence, Average absorbed dose, absorbed dose at any depth in the medium and practical range.
