This system has the longest (along the beam-line) target cell to date for an evaporation fridge, this requires a unique microwave distributing horn and three NMR coils per target cell to further reduce systematics in the polarization measurement.  This system was configured with the intention of having the greatest instantaneous luminosity of any previous evaporation system by having a beam intensity of 3X1012 protons/sec for 5 seconds while using a large pump system (14,000 m3/hour).  We are also running an experiment with both polarized protons and neutrons which share different sensitivity to the overall figure of merit of the Drell-Yan asymmetry.
