Instrumentation for the Tevatron Beam Dump

A graphite core beam dump designed to accept aborted protons from both the Main Ring and the Tevatron has been installed at Fermilab. Instrumentation was designed and constructed to monitor the integrity of the dump, the temperature at various locations about the core, and the position of the beam at the front face of the dump. These devices include calorimeters, temperature sensing devices, and an ionization chamber. Constraints were placed on the choice of materials used due to expected maximum temperatures of 400/degree/C and accumulated doses over 10 years of up to 10/sup 10/ R. Presented in this study are details of the choice of materials for and the design and construction of the desired instrumentation. 5 refs.
