Title: Design of the Mainz Active Polarized Target
Abstract:
At the Institut für Kernphysik in Mainz, Germany, the A2-Collaboration investigates the spin-polarizabilities of the proton by scattering experiments with spin-polarized energy-tagged photons. Due...

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...

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...
