Results of the measurement φ meson parameters with general purpose detector CMD-2 at upgraded e+e− collider VEPP-2M Novosibirsk are presented. This is first four major decay modes in a single experiment. The results based on about 55,600 identified hadronic events consistent previous measurements, and have precision comparable to current world average.
The decay φ→η′γ has been observed by the CMD-2 detector at e+e− collider VEPP-2M Novosibirsk. Of 5.5 million produced φ's, six events of were selected with expected background less than one event. corresponding branching ratio is B(φ→η′γ)=1.2+0.7−0.5·10−4. It first observation this radiative decay.
The use of nonlinear lattices with large betatron tune spreads can increase instability and space charge thresholds due to improved Landau damping. Unfortunately, the majority accelerator turn out be nonintegrable, producing chaotic motion a complex network stable unstable resonances. Recent advances in finding integrable have led proposal construct at Fermilab test strong focusing which avoids resonances particle motion. This presentation will outline main challenges, theoretical design...
The work is devoted to analytical study of application integrable systems round colliding beams, aiming at enhancement the beam-beam limit. Two examples "integrable" forces are presented, relevant counter beams with special density distributions. In such all resonances will vanish, hence effects can be suppressed, and intensities may strongly increased, least in "weak-strong" case.
Fermilab's Integrable Optics Test Accelerator is an electron storage ring designed for testing advanced accelerator physics concepts, including implementation of nonlinear integrable beam optics and experiments on optical stochastic cooling. The machine currently under construction at the Advanced Superconducting facility. In this report we present goals current status project, describe details design. particular, concentrate numerical simulations setting requirements design supporting...
Abstract A radiographic diagnostic has been developed to quantify the plume of erosion products after interaction between a target and relativistic electron beam. The is based on point Z-pinch (PZ-pinch) with metallic plasma jet. It creates an X-ray source typical size 10 μm, photon energy up 3 keV flash duration ns. visualization system thin scintillator CCD camera. spatial resolution was evaluated experimentally. frequency limit found be about 1.5 line pairs per millimeter. tested in...
Abstract Influence of backstreaming ions from the target on spot size focused 2 MeV electron beam was considered. The 2D version particle-in-cell code KARAT used to study formation stream and dynamics beam. It shown that light species emitted can disrupt emission low-ionized states tantalum cannot during about 30 ns or longer. A few non-invasive techniques mitigation disruption were Final magnetic lens with fast variation field several hundred Ampere-turns per nanosecond is capable stabilize...
