The successful commissioning and operation of the PEP-II asymmetric ee collider motivated further studies to increase luminosity. In this paper, we discuss a modification of the PEP-II lattice to reduce the vertical beta function at the Interaction Point (IP) from the design value of β∗ y = 1.5cm to 1.0cm. This could potentially reduce the colliding beam size, increase the particle density at I...

The best method of measuring CP violating effect in neutrino oscillation experiments is to construct and use a neutrino beam made of an ideal mixture of ν̄e and νe of monochromatic lines. The conceptual design of such a beam is described, together with how to measure the CP-odd quantity. We propose to exploit an accelerated unstable hydrogen-like heavy ion in a storage ring, whose decay has both...

The Spallation Neutron Source (SNS) is being designed, constructed, installed, and commissioned by the staff of six national laboratories, Argonne National Laboratory, Brookhaven National Laboratory, Jefferson National Accelerator Laboratory, Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, and Oak Ridge National Laboratory. The accelerator systems are designed to deliver ...

This report summarises the conclusions from the detector group of the International Scoping Study of a future Neutrino Factory and Super-Beam neutrino facility. The baseline detector options for each possible neutrino beam are defined as follows: 1. A very massive (Megaton) water Cherenkov detector is the baseline option for a sub-GeV Beta Beam and Super Beam facility. 2. There are a number of ...

At the LHC, the effect of unavoidable long-range beam–beam collisions reduces the dynamic aperture, calling for a minimum crossing angle. A wire compensator partially cancels the effect of the long-range collisions, and may allow operation with reduced crossing angle or decreased beta function at the interaction point, thereby increasing the (virtual) peak luminosity. In this chapter, we descri...

Spontaneous radiation emitted from relativistic electrons undergoing betatron motion in a plasma-focusing channel is analyzed, and applications to plasma wake-field accelerator experiments and to the ion-channel laser (ICL) are discussed. Important similarities and differences between a free electron laser (FEL) and an ICL are delineated. It is shown that the frequency of spontaneous radiation ...

As a quite novel concept for producing pure flavour neutrino beams, the beta-beam project presents several R&D challenges requiring careful studies. In the centre of these, the production of radioactive ion beams of beta-decaying nuclides of intensities orders of magnitudes higher than achieved so far has triggered various investigations. This article focuses on the production and beam preparat...

In the last few years spectacular results have been achieved with the demonstration of non vanishing neutrino masses and flavour mixing. Here, a novel method to create a monochromatic neutrino beam, an old dream for neutrino physics, is described based on the recent discovery of nuclei with fast decay through electron-capture to Gamow-Teller resonances in super allowed transitions. Such nuclei ...
