nEDM R&D
Gold plated ultra-pure copper is used to provide thermal contact from the dilution refrigerator to the grooved acrylic cell.
Pyrex injection cell is one important part of the nEDM experiment.

Gerasimov-Drell-Hearn (GDH) sum rule
The GDH sum rule provides an elegant connection between the nucleon excitation spectrum and its static properties.
Transversity
Neutron TRANSVERSITY experiment will study nucleon transverse spin structure together with other transverse momentum dependent structure functions (TMDs).
Proton Charge Radius
The proton charge radius (PRad) experiment in Hall B at Jefferson Lab.
JLab
JLab's CEBAF accelerator provides continuous electron beam up to 12 GeV after the upgrade with four experimental halls.
Hall-A at JLab
The two High Resolution
Spectrometers (HRS) in Hall-A are designed for detailed investigation of nuclear structure.
Injection Test
Test the polarization loss of 3He injected from the ABS and collected within superfluid 4He at 0.3 - 0.5K. Very important part of the new nEDM experiment.
Relaxation time
3He relaxation time measurement from dTPB coated acrylic cell at 1.9K and 0.3 - 0.5K.
Duke FEL Lab
The storage ring based FEL provides precisely tunable coherent radiation and a novel light source (Hiγs) with unprecedented photon flux by internal backscattering.
