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 <f>6LiD</f> in 2001. Deuteron polarizations of <f>+54.2%</f> and <f>−47.1%</f> were achieved in a <f>3He/4He</f> dilution refrigerator at a magnetic field of <f>2.5 T</f>. The equal spin temperature (EST) concept was found to hold among the deuteron, the <f>6Li</f> and the <f>7Li</f> 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. [Copyright &y& Elsevier]
