100. The Dynamic Nuclear Polarization Program at ORNL

Mikhail Yurov (Oak Ridge National Laboratory)

9/25/24, 9:00 AM

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...

59. SpinQuest Polarized Target System

Mr Vibodha Bandara (University of Colombo , University of Virginia)

9/25/24, 9:20 AM

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...

66. Beam Commissioning Result of Polarized Target at SpinQuest

Kenichi Nakano (University of Virginia)

9/25/24, 9:40 AM

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...

82. Designing targets, from low to very high power with CFD

Silviu Covrig Dusa (Jefferson Lab)

9/25/24, 10:00 AM

Computational fluid dynamics (CFD) has played an essential role in designing high performance targets. I will review the experience accumulated at Jefferson Lab in designing polarized and unpolarized targets with CFD.
