A polarized 3He target for the photon beam at MAMI

abstract:

A polarized 3He target has been installed for the first time inside the 4p Crystal Ball detector at the tagged photon beam of the MAinz MIcrotron (MAMI). It has been demonstrated that the system works reliably and that the polarization losses during handling of the polarized gas are under control. Initial polarization values up to 70% and total relaxation times up to 20 h could be obtained during a first test beam time devoted to the measurement of the double polarized photoabsorption cross-section in the Dð1232Þ baryon resonance region.
