A facility to Search for Hidden Particles (SHiP) at the CERN SPS

A new general purpose fixed target facility is proposed at the CERN SPS accelerator which is aimed at exploring the domain of hidden particles and make measurements with tau neutrinos. Hidden particles are predicted by a large number of models beyond the Standard Model. The high intensity of the SPS 400~GeV beam allows probing a wide variety of models containing light long-lived exotic particles with masses below ${\cal O}$(10)~GeV/c$^2$, including very weakly interacting low-energy SUSY states. The experimental programme of the proposed facility is capable of being extended in the future, e.g. to include direct searches for Dark Matter and Lepton Flavour Violation.Comment: Technical Proposa

COMPOSITION AND METHOD FOR SYNTHESIS OF SCINTHILLATION CERAMICS BASED ON NANOPOWDER

FIELD: chemistry. SUBSTANCE: group of inventions relates to the field of scintillation technology used to register ionizing radiation. Disclosed is the composition of scintillation ceramics based on yttrium alumina garnet doped with cerium ions (Ce3+:Y3Al5O12) made of a mixture of nanopowders of yttrium oxide doped with cerium ions (Ce:Y2O3), aluminum oxide (Al2O3), and yttrium oxide (Y2O3). Yttrium oxide is added to maintain stoichiometry, if necessary. The composition contains a sintering additive. Zirconium (Zr) is used as a sintering additive in the form of zirconium oxide ZrO2 with the content of 0.05-0.15 wt.%. EFFECT: increased speed of the ceramic scintillator without reducing the glow intensity. 2 cl, 2 dwg, 1 tbl.Группа изобретений относится к области сцинтилляционной техники, применяемой для регистрации ионизирующих излучений.
