Description
The Collaboration measures the integrand of the GDH integral for the deuteron
below 20 MeV. Mono-energetic and polarized intensive gamma rays produced by
HIγS at Duke Free Electron Laser Laboratory are incident on longitudinally
polarized deuteron target, using HIFROST. Neutrons from photodisintegration
reaction on the deuteron target are detected by 88 BC505 liquid scintillators, which
cover ¼ of 4π. This is the first experiment using the polarized target at HIgS,
HIFROST. For the initial measurements, beam energies of 8, 12, 16 MeV are
employed. I will talk about the target system HIFROST as well as measurement.
