Polarized Solid Targets III
- Chris Keith (Jefferson Lab)
The ORNL High Flux Isotope Reactor’s IMAGINE instrument facilitates a wide array of biological structure and function studies. Notably, the neutron scattering experiments performed with this single-crystal diffractometer provide atomic-resolution insights into macromolecular protein crystals structure. The sensitivity of neutron macromolecular crystallography can be significantly enhanced by...
The SpinQuest experiment at Fermilab uses a solid-state polarized ammonia target held at a magnetic field of 5 T, immersed in liquid helium-4, which is held at approximately 1K by the evaporation refrigerator. The refrigerator provides the required cooling power during the dynamic nuclear polarization (DNP) process and the high intensity interaction with the 120 GeV proton beam from the...
SpinQuest is a fixed-target experiment at Fermilab to measure the Drell-Yan process using transversely polarized NH$_3$ and ND$_3$ targets and unpolarized 120-GeV proton beam. In the Drell-Yan process, a quark in one scattering hadron and an anti-quark in the other hadron annihilate into a virtual photon and then decay into a muon (lepton) pair. The angular distribution of final-state muon...
