Polarized Targets
Talk
Polarization target for using hadron experiment is developing and studying in RCNP, Osaka University. LEPS group have studied hadron photo-production experiment of the \phi, K, \eta, and \pi^0 mesons by using linear polarized Back Scattering Compton (BCS) \gamma-ray and no polarized target with energies of E\gamma=1.5 ∼ 2.9 GeV. An experiment for measuring a complete set of spin observables is...

Polarized Targets
Talk
The polarized target group at Bonn operates a dilution refrigerator for double polarization experiments at the Crystal Barrel in Bonn. To get high target polarizations and long relaxation times low temperatures are indispensable. To reach temperatures below 30 mK and to allow for the use of an internal polarization magnet, the polarized target group is building a new continuous mode dilution...

Polarized Targets
Talk
The dynamic polarisation of nuclear spins requires the introduction of paramagnetic centres into potential target materials. A method of choice is the irradiation of such materials, in particular the inorganic materials lithium hydride and ammonia have been used in many nuclear and particle physics experiments with much success. As established as these materials are, a solid target material...

Polarized Targets
Talk
The Dynamic Nuclear Polarization (DNP) is an efficient technique to enhance the nucleus polarization by the so-called ´Radiation doping´ or ´Radical chemically doping´ methods in the field of polarized solid targets for their use in nuclear and particle physics experiments $^1$. Polymer materials have been used since 1994 due
to the advantage of its easy handling at room temperature and shape...

Polarized Targets
Talk
In the research field of polarized target physics the Q-meter is a well established technique to determine the polarization and relaxation behavior of a polarized solid target. One of the most common Q-meter modules is represented by the so called Liverpool-NMR, which was originally developed for the EMC experiment in the 1970s. However, since the module was build nearly 40 years ago, many...
