Abstract
Energy resolution is determined by fluctuations in the transformation of deposited energy to ionization and excitation. For noble gases, adding a molecular impurity that introduces a strong Penning effect reduces the Fano factor, improving energy resolution. I show that in xenon, adding trimethylamine (TMA) may provide a strong Penning effect and also permit electroluminescence (EL) at wavelengths characteristic of TMA. This combination may permit a large TPC to be operated with better than "intrinsic" energy resolution in the search for neutrino-less double beta decay in 136Xe. This path is being explored within the context of the NEXT collaboration.
