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).

Hall-B at JLab

The CEBAF large acceptance spectrometer (CLAS) is a nearly 4π detector used to study photo- and electro-induced nuclear and hadronic reactions.

JLab

JLab's CEBAF accelerator provides continuous electron beam upto 6 GeV and there's a $310M upgrade project to double the beam energy to 12 GeV.

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.
