Abstract
The COMPASS (NA58) experiment at CERN operates with a large solid polarized target (PT) to study the spin structure of the nucleon. The COMPASS PT system started its operation with the target material 6LiD in 2001. Deuteron polarizations of +54.2% and −47.1% were achieved in a 3He/4He dilution refrigerator at a magnetic field of 2.5 T. The equal spin temperature (EST) concept was found to hold among the deuteron, the 6Li and the 7Li nuclei during the dynamic nuclear polarization (DNP) process. The agreement with the EST concept allows the permanent monitoring of only one nuclear species by the nuclear magnetic resonance (NMR) method.
