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.
