Test of the Optical Readout of the UConn TPC Detector

The UConn Time Projection Chamber (TPC) detector is being constructed as a UConn-Yale-Weizmann-PTB-TUNL-LLN collaboration to measure at the HI$\gamma $S at TUNL the $^{16}$O($\gamma $,$\alpha )^{12}$C reaction of importance for stellar evolution theory. We are currently constructing the readout system of this TPC using the optical chain of the CERN-CHORUS neutrino experiment. The Contrast Transfer Function (CTF) across the entire chain was measured at the Lab at PTB, Braunschweig, Germany, using a CCD camera and it was found be sufficient (sub-millimeter resolution) for resolving the expected tracks of particles in the TPC. Results of this measurement will be presented.
