> Title:  A High Luminosity Polarized Helium-3 target for various experiments in Halls A and C of Jefferson Lab
> Abstract: The A1n, d2n, GEn-II and A_LL experiments at Jefferson lab utilized a high luminosity polarized 3^He target to make precise measurements at high x and/or Q^2 settings. This polarized 3^He target consists of a pumping chamber (where polarization of He3 takes place), a target chamber (where e- beam interacts with the target material) and transfer tubes (which facilitate a convective flow of the polarized material). Helium-3 gas at ~8 atm pressure is filled into these glass cells along with Rb-K alkali mixture and high power narrow band diode lasers are used for polarizing the 3^He using a Spin Exchange Optical Pumping (SEOP) based technique. The target system used in the experiment includes Helmholtz coils to create a holding field that determines the direction of polarization for the 3^He nuclei. Two polarimetry techniques are used to determine the absolute (EPR) and relative (EPR) polarization during production running. Physics goals of these experiments and the overall target performance will be discussed in this talk.
