Dr Yury Usov (JINR)17/09/2015, 09:00TalkA frozen spin polarized targets cooled by the $^3$He/$^4$He dilution refrigerator developed at Dubna are described. Experience with continuously dynamic polarized target and achieving of very low temperatures in 1966 (JINR) gave rise to the idea of using radically new technique based on dissolving $^3$He in $^4$He in the frozen--spin polarized target. The short history (1976-2015) of the...Go to contribution page

Josh Pierce (ORNL)17/09/2015, 09:30TalkNeutron scattering off of protein crystals has been used successfully to determine protein structure. This technique achieves its best results when used with large crystal samples, or with samples that are amenable to techniques such as deuteration. In the case of small or delicate protein crystals, sample polarization has been identified as a method to greatly increase the signal to noise...Go to contribution page

Ms Farah for the A2-Collaboration Afzal (HISKP, University of Bonn)17/09/2015, 10:00TalkThe understanding of the nucleon excitation spectra requires the measurement of several polarization observables in addition to the unpolarized cross section. The Crystal Ball experiment at MAMI has measured for the first time the double polarization observables E and G simultaneously within one beam time. The simultaneous production of linearly (needed for G) and circularly (needed for E)...Go to contribution page
