The ultimate goal of my research is to measure for photons between 8 and 20 MeV using a froz en-spin target originally constructed at CERN in the mid 1970&rsquo\;s. Th e goal is to 1) look for a dibaryon state of the deuteron and to 2) invest igate suspected deviations of the Gerasimov-Drell-Hearn integrand. In orde r to make sure we are as prepared as possible\, we practice operation of t he target in our lab. The primary goal of these practice runs or &ldquo\;c ooldowns&rdquo\; is to achieve the ideal ratio of Helium-3 and Helium-4 in the target chamber of our dilution refrigerator in order to get it down t o the coldest temperature possible and then to measure the polarization of the target. However\, we have hit a few bumps along the way\, and cannot currently do cooldowns due to our dilution fridge leaking. The primary foc us of my talk will be on the steps we have taken to fix our fridge and get back to doing proper cooldowns.
