The development of effective and eco-friendly cooling technology demands an investigation new magnetocaloric materials. Compounds containing gadolinium are one the best candidates due to large spin-only magnetic moment Gd3+ ions. This work reports on properties AGdS2 family (A = Li, Na, K, Rb) in relation crystal chemistry these compounds. These sulfides crystallize two different structure type...

Abstract The European Spallation Source (ESS) is a neutron-scattering facility funded and supported in collaboration with 13 countries Lund, Sweden. Cryogenic cooling at ESS vital particularly for the linear accelerator, hydrogen target moderators, test stand cryomodules, neutron instruments their sample environments. paper will focus on control system design different cryogenic subsystems, har...

deep cryogenic heat treatment is assumed as a supplementary heat treatment performed on steels before the finaltempering treatment to enhance the wear resistance and hardness of the steels. in this study, the effects of thedeep cryogenic heat treatment on the wear behavior and corrosion resistance of the 1.2080 tool steel were studiedusing the wear testing machine and polarization and impedance...

This paper describes the design and testing of first cryogenic rotor based on conductively cooled superconducting stacked tape pseudo bulks used in a rotating machine with various magnetisation methods. The demanded number unusual features constraints that required novel, innovative solutions may be applicable other designs. aim this work is not to create complete manual, rather, suggest some i...

In recent years widely tunable terahertz- (THz-) wave generation from LiNbO(3) optical parametric oscillators (OPO's) has been successfully demonstrated by use of the prism output-coupler method. However, there remains a problem of large absorption loss for generated terahertz waves inside the crystal, so we investigated the cryogenic characteristics of the OPO. We achieved 125-times-higher THz...
