Abstract

This year I worked with Professor Averett to fill and analyze several $^3$He target cells. Many of these cells are taken from our lab to eventually be used as targets at Jefferson Lab for nuclear physics experiments. Our ultimate goal was to test a number of different variables in an attempt to improve the lifetimes of future targets. Over the course of this year we tested several different cells and eventually got some improvements in our cell lifetimes due to a couple factors, including a new tubing getter and larger cell size. We have not quite identified exactly what was causing the previous targets to have poor lifetimes, but we have developed a method that seemed to produce cells with longer lifetimes. The testing of these processes is not complete, but getting a couple of improved cells is very promising.
