We report precision determinations of the beam-normal single spin asymmetries (A_{n}) in elastic scattering 0.95 and 2.18 GeV electrons off ^{12}C, ^{40}Ca, ^{48}Ca, ^{208}Pb at very forward angles where most detailed theoretical calculations have been performed. The first measurements A_{n} for ^{40}Ca ^{48}Ca are found to be similar that consistent with expectations thus demonstrating validity nuclei Z≤20. also two new momentum transfers (Q^{2}) extending previous measurement. Our data...
The aim of this study was to retire the risk maintaining integrity S2-glass reinforced CTD-403 (a cyanate ester resin) that is exposed radiation and elevated temperature over life MOLLER experiment in experimental Hall A at Jefferson Lab. In paper, shear strength flexural modulus irradiated specimens were measured 65 °C (the magnets are operate less than °C) under two scenarios: vacuum gaseous nitrogen. testing method Short-Beam Shear (SBS) test according ASTM D2344. neutrons gamma-rays up...
The aim of this article is to develop a risk management procedure, which could be applied the magnet design process, for both superconducting and normal magnets at Jefferson Laboratory (JLab). This procedure allowed us identify key risks each critical phases propose procedures, tests, checks mitigate risk. In article, we present qualitative quantitative commonly referred "failure modes effects analysis." As part calculated priority number (RPN) activity identified most activities proposed...
We propose to measure the beam normal single spin asymmetry in elastic scattering of transversely polarized electron from target nuclei with 12 $\leq Z \leq$ 90 at Q$^2$ = 0.0092 GeV$^2$ study its nuclear dependence. While theoretical calculations based on two-photon exchange suggest no dependence this kinematics, results 208Pb Jefferson Lab show a striking disagreement both predictions and light measurements. The proposed measurements will provide new data for intermediate heavy where...
