The Integrable Optics Test Accelerator (IOTA) is a storage ring for advanced beam physics research currently being built and commissioned at Fermilab. It will operate with protons electrons using injectors momenta of 70 150 MeV/c, respectively. program includes the study nonlinear focusing integrable optical lattices based on special magnets electron lenses, dynamics space-charge effects their compensation, stochastic cooling, several other experiments. In this article, we present design...
The spectra of levels in the hypernuclei $_{\ensuremath{\Lambda}}^{13}\mathrm{C}$, $_{\ensuremath{\Lambda}}^{14}\mathrm{N}$, and $_{\ensuremath{\Lambda}}^{18}\mathrm{O}$, excited by 800-MeV/c kaons (${K}^{\ensuremath{-}}$,${\ensuremath{\pi}}^{\ensuremath{-}}$) reaction, have been observed at Brookhaven alternating-gradient synchrotron. Data were recorded for scattering angles from 0\ifmmode^\circ\else\textdegree\fi{} to 25\ifmmode^\circ\else\textdegree\fi{}, corresponding momentum transfers...

In both cases, $\ensuremath{\gamma}$ ray $_{\ensuremath{\Lambda}}^{A}Z$ is very close to first excited state nuclear core.

We describe the magnet challenges for a Muon Collider, an exciting option considered future of particle physics at energy frontier. Starting from comprehensive work performed by US Accelerator Program, we have reviewed performance specifications dictated beam and operating conditions to satisfy accelerator needs. Among many magnets that make up muon collider, identified four systems represent well envelope challenges: target capture solenoid, final cooling dipoles collider dipoles. These...
We report results of the experimental test High Temperature Superconductor based fast cycling prototype accelerator magnet capable to operate up about 300 Tesla per second field ramping rate with some 0.5 T in gap. The measured upper limit for cryogenic cooling power required support conductor operation at high rates indicates great potential such types magnets rapid synchrotrons neutrino research or muon acceleration. design, construction, and supporting systems are briefly described....

The K0SK0Sπ0 systems, a pure C=+1 state, has been studied in the reaction π−p→K0SK0Sπ0n at 21.4 GeV/c. spectrum is significantly different from K¯Kπ distribution observed other lower-energy peripheral hadroproduction experiments. In addition to production of f1(1285), evidence for η(1460) [sometimes called ι(1460)] based on mass spectra and Dalitz-plot spin-parity analysis reported. narrower, lower-mass state experiments weakly if all this experiment. Hadronic η(1460), which good glueball...
Four decades ago development of high-current superconducting NbTi wire cables revolutionized the magnet technology for energy frontier accelerators, such as Tevatron, RHIC and LHC. The based magnets offered advantage much higher fields B lower electric wall plug power consumption if operated at 4.5 K but relatively small ramping rates dB/dt << 0.1 T/s. need accelerators high average beam repetition have initiated studies fast SC magnets, it was found AC losses in low-temperature...
Development of energy-efficient fast cycling accelerator magnets is critical for the next generation proton rapid synchrotrons (RCS) neutrino research and booster accelerators future muon colliders. We see a unique opportunity having such to be built on base High Temperature Superconductors (HTS). Besides being superconducting at relatively high temperatures, rare-earth HTS tapes have shown very small AC losses compared low-temperature NbTi superconductor cables. Recent tests HTS-based 0.5 m...
A strong candidate for the Standard Model Scalar boson, H(126), has been discovered by Large Hadron Collider (LHC) experiments. In order to study this fundamental particle with unprecedented precision, and perform precision tests of closure Model, we investigate possibilities offered An e+e- storage ring collider. We use a design inspired B-factories, taking into account performance achieved at LEP2, imposing synchrotron radiation power limit 100 MW. At most relevant centre-of-mass energy...

Particle accelerators and storage rings have been transformative instruments of discovery, and, for many applications, innovations in particle-beam cooling a principal driver that success1. Beam reduces the spread particle positions momenta, while keeping number particles constant, combats diffusive effects, thereby enabling accumulation production preservation intense beams. In case colliders, increases likelihood observing rare physics events. One most important conceptual technological...
