Title Parity Violating Deep Inelastic Electron Scattering from the Deuteron at 6 GeV
Abstract An experiment that measured the parity violating (PV) asymmetry Ad in e-2H deep inelastic scattering (DIS) at Q2  1.10 and 1.90 (GeV/c)2 and xB  0.3 was completed in experimental Hall A at the Thomas Jefferson National Accelerator Facility. The asymmetry can be used to extract the neutral weak coupling combination (2C2u-C2d), providing a factor of five to six improvement over the current world data. To achieve this precision, asymmetries of the 10?4 level needed to be measured at event rates up to 500 kHz with high electron detection efficiency and high pion background rejection capability. A specialized scaler-based counting data acquisition system (DAQ) with hardware-based particle identification was successfully implemented. The statistical quality of the asymmetry measurement agreed with the Gaussian distribution to over five orders of magnitudes and the experimental goal of 3-4% statistical uncertainty was achieved. The design and performance of the new DAQ system is presented w
