“…Beyond some point, the benefit of low beam temperature is offset by increased scattering losses and deteriorating degree of dissociation at a low nozzle temperature. A nozzle temperature of 65-80 K is common [198,202,217], but a temperature of 35 K with correspondingly reduced gas throughput (scattering losses) has been used for applications where beam density rather than intensity was of primary interest [33,45,57,89,189].…”

This review describes the development and present performance of nuclear polarized gas targets in nuclear or particle physics experiments. After a brief account of the various development steps, the design principles for the relevant light nucleon targets, hydrogen, deuterium and 3 He, for storage rings, are discussed. Most of these targets make use of so-called storage cells in order to enhance the target thickness. The performance of targets used in medium and high-energy ion and electron storage rings is reviewed. Finally, future trends and possible improvements are discussed.

“…There is good evidence that condensation of water vapour on the nozzle reduces surface recombination. For very cold nozzles (35 K), the large decrease in α for nozzle temperatures below ∼70 K can be alleviated by addition of N 2 [189].…”

High-precision measurements of the cross section, the vector analyzing power iTtl and the three tensor-analyzing powers T2o, T21 , and T22 of the 3He(d, p)*He reaction have been performed in the energy range between 1.0 and 13.0 MeV in steps of 1 or 2 MeV. Angular distributions of the cross section have been obtained between 22.5 ~ and 157.5 ~ in the laboratory system. The polarization observables have been measured between 10 ~ and 170 ~
