We study the time evolution of the beam current in the Fermilab Recycler Ring due to abrupt physical processes (single coloumb scattering, nuclear scattering) that cause sudden loss of beam, and diffusive processes (multiple coloumb scattering, lattice dpendence, etc.) which cause emittance growth. This emittance growth combined with finite aperure of the beam pipe will lead to eventual loss of...

A novel method for beam manipulation, compression, and stacking using a broad band RF system in circular accelerators is described. The method uses a series of linear voltage ramps in combination with moving barrier pulses to azimuthally compress, expand, or cog the beam. Beam manipulations can be accomplished rapidly and, in principle, without emittance growth. The general principle of the met...

Transverse resistive wall instability is analysed for antiprotons in the Recycler Ring. Damper requirements are formulated. 1 Growth Rate and Landau Damping 1.1 Coasting Beam Coherent instabilities are driven by the real part of impedance. For a coasting beam with insigni…cant frequency spread, the impedance-driven coherent tune shift at the harmonic number n is given by (see e. g. [1]) Z !Z=!0...

A flame shape descriptor based on coordinates of edge of a flame is proposed. Artificial Neural Network is used to predict flame image edges .A flame with constant x-coordinate is used in the present study. Y-coordinates of flame edge are predicted using neural network. Recognition experiments were carried out using flame image sampled from a burning candle. The results show a good recognition ...

With the widespread adoption of e-mobility, there are high numbers lithium Ion batteries (LIB) entering waste stream. It is imperative that disposal and recycling strategies developed implemented. There an urgent need for safe, environmentally friendly economically affordable routes End Life (EoL) LIBs. This study has looked at 44 commercial recyclers assessed their reclamation processes. A nov...

Executive Summary The objective of this study was to examine the technology and infrastructure of paper recycling in New York City and devise ways for increasing paper recovery. At present, " residential " wastepaper is collected as a separate stream by the Department of Sanitation of New York City (DSNY). In 2003, DSNY collected approximately 414,960 tons of paper, i.e. about 35 percent of the...

Hospital wastewater is a source of pollutants for the environment that can have negative impact. waste contain various kinds microorganisms depending on type hospital and level treatment carried out after disposed of. Therefore, it necessary to conduct study Wastewater Treatment Plants so discharged meets requirements from hospital. From results this be concluded initial process final check qua...

background: waste produced in dental clinics has been the topic of investigations for many years. these waste materials have important health impacts and are hazardous to humans and the environment. objective: to investigating solid waste production and its management in dental clinics in gorgan, northern iran. methods: in this cross-sectional study, 45 of 143 public dental practices and 5 of 2...

Internet + platform recycling is a new model of that provides more ways to recycle WEEE. Considering consumers’ preference for channels, we construct single-channel reverse supply chain (Model-S) and two dual-channel models (Model-DU Model-DD) consisting recycler an e-platform consider the unified pricing differentiated strategies in models. By solving optimal decisions members using game theor...
