Description

Full text: The graphite calorimeter was developed for absolute measurements of absorbed dose to water at NMIJ/AIST, Japan. To minimize the influence from outer temperature, the core area is covered with jacked and shield layer. The temperature-measuring thermistor of the core is connected to a AC Wheatstone bridge, and the resistance change is measured by lock-in amplifier and nano voltmeter. Some correction factors for evaluation of absorbed dose to water were estimated by EGS5 Monte Carlo simulations. (author)
