A facility producing neutrinos from muons that decay in a storage ring can provide an extremely well understood neutrino beam for oscillation physics and the search for sterile neutrinos. The "neutrinos from STORed Muons"(nuSTORM) facility is based on this idea. The facility includes a target station with secondary particle collection, pion transfer line, pion injection, and a ~3.8 GeV/c muon storage ring. No muon cooling or RF sub-systems are required. The injection scenario for nuSTORM avoids the use of a separate pion decay channel and fast kickers. This paper reports a detailed description of the proposed injection scheme with full G4beamline simulations. We also present progresses on possible design options for a muon racetrack decay ring.

  Intra-Beam Scattering (IBS) can cause emittance growth in high intensity low energy beams. We study its effect on the compact low energy electron storage ring, proposed for Tsinghua Thomson Scattering X-ray source (TTX). For a single bunch with peak current at about 17A and re-entrant type normal conducting RF cavity with peak voltage at 15kV, the equilibrium horizontal and vertical emittances are 2.9 and 0.3 μm, and the rms momentum spread and bunch length are about 0.2%, and 23ps. In this paper, we report the methods and results of the IBS calculation.

  Tsinghua Thomson scattering X-ray (TTX) source, proposed by Tsinghua University, is a hard x-ray source with multi-application in condensed matter physics, etc. The TTX is composed of an S-band photocathode RF gun and a SLAC type 3m travelling wave Linac, and a femto-second tera-watt laser system drives the photocathode. The TTX source is in operation. To extend the capability of TTX, we plan to design a ring based system to increase the photon flux. In this paper, we report the design of the compact electron storage ring and optical cavity, expected performance, and future prospects.
