“…At 300 mK temperature and at a magnetic field of 6.5 T 70% 6Li polarization has been measured [36,37]. Other studies have confirmed the polarizability of "iD [38-401. The experiments will detect open charm production through various D meson decays.…”

Our interest in understanding the spin content of the nucleon has left its marks on the recent development, of the dynamic nuclear polarized (DNP) targets. This can be seen from the targets developed at CERN and SLAC for the measurement of the polarized spin structure functions in deep inelastic scattering. The results of the experiments indicated that less than 30% of the nucleon spin is carried by the quarks. This unpredicted small value initiated planning of new polarized target experiments to determine the gluon polarization on the nucleon using polarized real photons and polarized 'LiD targets. In several facilities very intense polarized photon beams are available at a wide energy range. During the next few years these photon beanis with DNP targets will be used to test the fundamental GDH sum rule. Other DNP target developments are also discussed.

“…RADIATION-DOPED LITHIUM HYDRIDES AND DEUTERIDES Pioneering work to prepare 7 LiH, 6 LiH, and 6 LiD for the DNP process has been done by different groups at Saclay (70)(71)(72)(73) and recently in Bonn (74). At room temperature, the lithium compounds are in their solid state phase, and the paramagnetic impurities (so-called F-centers) are introduced by irradiation.…”

The development, in the early 1960s, of the dynamic nuclear polarization process in solid diamagnetic materials, doped with paramagnetic radicals, led to the use of solid polarized targets in numerous nuclear and particle physics experiments. Since then steady progress has been made in all contributing subsystems so that proton polarizations near 100% and deuteron polarizations higher than 50% have been achieved in various materials. More radiation-resistant materials, such as ammonia, have made it possible to perform experiments with high beam intensities and experiments that benefit from 4 He cooling at 1K and high magnetic fields. The development of dilution refrigerators have allowed frozen spin operation so that experiments with large angular acceptance for the scattered particles have become routine. Many experiments have taken advantage of these developments and many more are being planned, especially with electromagnetic probes.

“…For this reason, the 6LiD material contains a half of polarizable nucleons. First measurements of the 6LiD polarization was carried out by A.Abragam's group at Saclay [19]. Samples of a few mm 3 were used and 6LiD polarizations of 40% in a field of 2.5 T and 71% in a field of 6.5 T were achieved.…”

Experience with polarized targets and achieving of very low temperatures gave rise to the idea of using a new technique based on dissolving 3He in 4He to create a frozen spin polarized target. The short history of the development of such proton and deuteron targets at the Laboratory of Nuclear Problems (LNP) JINR is given. Kecently, the Saclay-Argonne frozen spin proton polarized target used initially in E704 experiment at FERMILAB was upgraded with adding the missing parts and the first physics experiments was carried out.
