The European Commission DG Research brochure contains project factsheets for FP7 funded Integrated Activities projects. Each factsheet is one page (recto-verso) detailing the general aims and scope of the project. The factsheets are directed at the general public

Nowa seria wydawnicza Politechniki Warszawskiej "Technika Akceleratorowa"

The new Editorial Series of short research and didactic monographs on “Accelerator Technology” or in Polish “Technika Akceleratorowa” is devoted to all aspects of the research, design, construction, testing, commissioning and exploitation of very complex components and apparatus for particle accelerators, detectors, energy and particle sources, astrophysics and high energy physics experiments. A short, symbolic, title of the editorial series “Accelerator Technology”, embraces a large and flourishing branch of scientific activity. The monographs to be published in the series will be around 100 pages, usually not exceeding 150, and will provide a very concise and in depth discussion of relevant, narrowly defined topics. The books will be published in English, usually by international experts. They are mainly intended for students as well as young and new to the field engineers and physicists, as a fast start up for further and more advanced studies. The books originally stem from the EU FP6 CARE Project - Coordination of Accelerator Research in Europe and are successfully continued in the EU FP7 EuCARD Project - European Coordination of Accelerator Research. The editorial series was initiated by dr Roy Aleksan of CEA. The books were added to the EuCARD as a contractual item

Simulations of beam-beam and beam-wire interactions in RHIC

The beam-beam interaction is one of the dominant sources of emittance growth and luminosity lifetime deterioration. A current carrying wire has been proposed to compensate long-range beam-beam effects in the LHC and strong localized long-range beam-beam effects are experimentally investigated in the RHIC collider. Tune shift, beam transfer function, and beam loss rate are measured in dedicated experiments. In this paper, we report on simulations to study the effect of beam-wire interactions based on diffusive apertures, beam loss rates, and beam transfer function using a parallelized weak-strong beam simulation code (bbsimc). The simulation results are compared with measurements performed in RHIC during 2007 and 2008.Comment: 15 pages, 36 figures, submitted to HB2008 PRST-AB Special Editio

EXPERIMENTS WITH A DC WIRE IN RHIC

A DC wire has been installed in RHIC to explore the long-range beam-beam effect, and test its compensation. We report on experiments that measure the effect of the wire's electro-magnetic field on the beam's lifetime and tune distribution, and accompanying simulations

A Very Intense Neutrino Super Beam Experiment for Leptonic CP Violation Discovery based on the European Spallation Source Linac: A Snowmass 2013 White Paper

Very intense neutrino beams and large neutrino detectors will be needed in order to enable the discovery of CP violation in the leptonic sector. We propose to use the proton linac of the European Spallation Source currently under construction in Lund, Sweden to deliver, in parallel with the spallation neutron production, a very intense, cost effective and high performance neutrino beam. The baseline program for the European Spallation Source linac is that it will be fully operational at 5 MW average power by 2022, producing 2 GeV 2.86 ms long proton pulses at a rate of 14 Hz. Our proposal is to upgrade the linac to 10 MW average power and 28 Hz, producing 14 pulses/s for neutron production and 14 pulses/s for neutrino production. Furthermore, because of the high current required in the pulsed neutrino horn, the length of the pulses used for neutrino production needs to be compressed to a few $\mu$s with the aid of an accumulator ring. A long baseline experiment using this Super Beam and a megaton underground Water Cherenkov detector located in existing mines 300-600 km from Lund will make it possible to discover leptonic CP violation at 5 $\sigma$ significance level in up to 50% of the leptonic Dirac CP-violating phase range. This experiment could also determine the neutrino mass hierarchy at a significance level of more than 3 $\sigma$ if this issue will not already have been settled by other experiments by then. The mass hierarchy performance could be increased by combining the neutrino beam results with those obtained from atmospheric neutrinos detected by the same large volume detector. This detector will also be used to measure the proton lifetime, detect cosmological neutrinos and neutrinos from supernova explosions. Results on the sensitivity to leptonic CP violation and the neutrino mass hierarchy are presented.Comment: 28 page

Lepton beam polarization at LEP

Results from studies on transverse polarization in LEP over the past two years are presented. A single beam transverse polarization level of 57% at 45 GeV was reached adopting strategies to compensate depolarizing effcts originating in the four experimental solenoids and from orbit pertubations. Beam Energy Calibration was performed by Resonant Depolarization during the 1993 LEP Run for Physics at three different energies centered around the Z peak. The uncertainty on the beam energy was reduced to about 1 MeV, thus improving the accuracy on the Z-resonance mass and width with respect to previous results. Successful results obtained at the end of the 1994 LEP Run on polarization with colliding beams are reported and future plans outlined
