39. The LHCspin project: a polarized target experiment at LHC

Paolo Lenisa (University of Ferrara and INFN)

9/26/24, 11:00 AM

A polarized gaseous target, operated in combination with the high-energy, high-intensity LHC beams and a highly performing LHC particle detector, has the potential to open new physics frontiers and to deepen our understanding of the intricacies of the strong interaction in the non-perturbative regime of QCD. Specifically, the LHCspin project aims to perform spin physics studies in high-energy...

51. Amorphous Carbon-coated Storage Cell Tests for the Polarized Gas Target at LHCb

Ralf Engels

9/26/24, 11:20 AM

The LHC beams cannot be polarized. Hence, the implementation of a dense polarized gas target at the LHCb experiment at CERN, to be operated simultaneously with beam-beam collisions, will enable fixed target interactions to explore a new energy range of spin physics measurements. Unfortunately, typical surface coatings like water, Teflon or aluminium, normally used to avoid polarization losses,...

48. Metastable exchange optical pumping to polarize ³He at high magnetic fields

Pushpa Pandey (Massachusetts Institute of Technology)

9/26/24, 11:40 AM

Recent advancements in Metastability Exchange Optical Pumping (MEOP) techniques have enabled the investigation of ³He nuclear spin polarization under high magnetic fields and varying gas pressures. At Jefferson Lab, we are employing MEOP of ³He nuclei at varying pressures using a fillable cell under magnetic fields ranging from 2 to 5 T. The current development focuses on creating a...

79. Polarized $^3$He Double-Cell Target Utilizing Metastability Exchange Optical Pumping at High Pressure and Magnetic Fields

Hao Lu (University of Tennessee)

9/26/24, 12:00 PM

The nuclear-spin polarized $^3$He is a crucial instrument for investigating the neutron's spin structure, effectively acting as a polarized neutron target. The latest advancements in metastability exchange optical pumping (MEOP) techniques within high magnetic fields have enabled the use of polarized $^3$He targets in strong magnetic field environments, such as Jefferson Lab's CLAS12...
