Power deposition measurements at 800 MeV-direct proton beam heating of target materials
- and others
A slug calorimetric sensor with several novel design features was developed to measure the power deposition in a cylindrical test article with lead, aluminum, polyethylene and tungsten components. A small, solid slug (volume = 347.5 mm{sup 3}) was suspended by Kevlar fibers and surrounded by an adiabatic enclosure in an insulating vacuum canister of stainless steel construction. A small, calibrated, 100-kOhm thermistor was placed in the slug to monitor the temperature. Power deposition caused by the passage of radiation through the slug was measured from the rate of temperature rise. Lead, tungsten, and Inconel-718 slugs were placed on the beam axis of the test article and were irradiated with an 800 MeV proton beam. The data from these sensors will provide an accurate determination of thermal power density and energy deposition from proton beams incident on target/blanket components of accelerator-based systems, such as the Accelerator Production of Tritium (APT) and the Spallation Neutron Source (SNS).
