ABSTRACT

With the use of various sensing equipment, a neutron spallation target was studied via experiments performed at the Los Alamos Neutron Science Center. The goal is to determine the characteristics of the target container and cavity which contains the liquid mercury. The sensing equipment developed by the Photonics and Measurement Systems Group within Engineering Technology Division includes fiber optic strain sensors, phosphor temperature sensors, and high sensitivity fiber optic diaphragm pressure sensors. The pressure and temperature of the mercury, along with the strain on the cavity, were measured during interaction with a 10^13 proton pulse having energies of 1 GeV.

The Fabry-Perot Interferometric Strain Sensor, Phosphor Temperature Sensor, and the High Sensitivity Diaphragm Pressure Sensor were used to record the characteristics of the target during the spallation experiments.
