Nuclear Physics Research at the High Intensity Gamma-Ray Source (HIγS)

The High Intensity γ-Ray Source (HIγS), operated by the Triangle Universities Nuclear Laboratory and located on the campus of Duke University, is presently able to provide nearly mono-energetic polarized gamma ray beams with energies ranging from 1 to 100 MeV. These beams are produced by Compton backscattering photons produced by a free-electron laser (FEL) from the same relativistic electron beam that powers the FEL inside of an electron storage ring. The maximum total intensity of these g-ray beams produced in the vicinity of 10 MeV is approximately 3 × 1010 γ/s, making HIγS the most intense Compton γ-ray source ever built and operated [1].
