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.
