Prototypes of Holding Magnet System
Abstract
New experiments have been proposed with the 4-pi JLab CLAS detector and a Frozen Spin Polarized Target located at the center of the detector. In such experiments, the target will be polarized outside the detector by a high field (5.0 Tesla) magnet at T=0.5 K. Afterwards another "low" field (0.5 Tesla) magnet will be used to hold polarization at T=0.05 K and the target will be moved inside the CLAS detector. The holding system should provide a homogeneous field high enough to keep a polarization for the time while experiment runs. Such an additional field can affect the proper workings of the CLAS detector. The simulation and the field mapping of prototype magnets have been done. We will present results for the both transversal and longitudinal holding magnets.
