The Q weak experiment, which completed running in May of 2012 at Jefferson Laboratory, has measured the parity-violating asymmetry in elastic electron-proton scattering at four-momentum transfer Q 2 =0.025 (GeV/c) 2 in order to provide the first direct measurement of the proton's weak charge, Q p w. The Standard Model makes firm predictions for the weak charge; deviations from the predicted value would provide strong evidence of new physics beyond the Standard Model. Using an 89% polarized electron beam at 145 µA scattering from a 34.4 cm long liquid hydrogen target, scattered electrons were detected using an array of eight fused-silica detectors placed symmetric about the beam axis. The parity-violating asymmetry was then measured by reversing the helicity of the incoming electrons and measuring the normalized difference in rate seen in the detectors. The low Q 2 enables a theoretically clean measurement; the higher order hadronic corrections are constrained using previous parity-violating electron scattering world data. The experimental method will be discussed, with recent results constituting 4% of our total data and projections of our proposed uncertainties on the full data set.

The Real Compton Scattering experiment was performed in Hall A at the Thomas Jefferson National Accelerator Facility. It was designed to measure, for Compton scattering and π 0-photoproduction, the differential cross section over a range of kinematic points and the polarisation transfer to the proton at a single kinematic point. The full range of the experiment in Mandelstam variables t and s was 1.64−6.46 GeV 2 and 4.82−10.92 GeV 2 respectively with beam energies of 2−6 GeV. The motivation for the experiment is to test the cross section and polarisation transfer predictions of perturbative QCD versus that of predictions from Generalised Parton Distribution models. This thesis will give an overview of the pertinent theory, experimental setup in Hall A and the extracting of the π 0-photoproduction cross section.

“…Rapid progress in the area of superconducting rf (SRF) accelerating structures (AS) technology, which began in the mid-1980s, made it a standard practice to use SRF AS for obtaining continuous high-energy beams with relatively low average current [3], as well as for high current energy recovery linacs [4].…”

Based on Skobeltsyn Institute of Nuclear Physics (SINP) Moscow State University (MSU) experience in developing continuous-wave (cw) normal conducting electron linacs, we propose a design for such accelerators with beam energy of up to 10 MeV and average beam power of up to several hundred kW. An example of such design is the 1 MeV industrial cw linac with maximum beam power of 25 kW achievable with 50 kW klystron, which was recently commissioned at SINP MSU.
