    Talk
    In the COMPASS Drell-Yan programme a negative hadron beam (97% π − , 2.5% K − and 0.5% p) with momentum 190 GeV/c is used. The beam intensity reaches up to 10$^8$ particles/s. The polarizable solid state NH3 target is placed inside the mixing chamber of a large horizontal helium-3/4 dilution cryostat. A large acceptance superconducting solenoid magnet with nominal field of 2.5 T is used...

  3. 46. Optimization in Tensor Polarized Targets
    Dustin Keller (University of Virginia)
    16/09/2015, 12:00
    Talk
    A discussion of achieving tensor polarization optimization of a spin 1 solid target to be used in scattering experiments is presented. Manipulation of the deuteron NMR line with selective RF semi-saturation at a temperature of 1 K and holding field of 5 T are discussed. Some measurement techniques with error estimation are outlined. Techniques in increasing the deuteron tensor polarization...
