In a colliding beam storage ring the Twiss parameters are a ected by the quadrupolar focusing of the beam{beam interaction. Like any quadrupole error this `dynamic beta' e ect is enhanced by running near a half{integer or integer resonance. The recent change in the operating point of CESR so that the horizontal tune is just above a half{integer resonance has resulted in the dynamic beta e ect h...

We consider two possible schemes for generation and detection of a monoenergetic directed beam of neutrinos which may have application to neutrino communication. First, we consider generation of a directed neutrino beam using electron capture beta decay in hydrogen-like ions. Next, we suggest detection of a directed neutrino beam using resonant absorption of a neutrino by a bare nucleus with th...

We describe the importance of having low-energy (10-100 MeV) neutrino beams produced through the decay of boosted radioactive ions (“beta-beams”). We focus on the interest for neutrino-nucleus interaction studies and their impact for astrophysics, nuclear and particle physics. In particular, we discuss the relation to neutrinoless double-beta decay. Finally, we mention the status as far as the ...

The ISAC II superconducting linac is presently in the beam commissioning phase. The linac lattice consists of modules of four quarter wave cavities and one superconducting solenoid. At the moment five cryomodules (indicated as medium beta section) are installed. Beam steerers between cryomodules compensate for steering effects due to misalignments in the solenoids. Beam dynamics aspects of lina...

of this setup is analysed as a function of the flux. We find that, for the highest flux considered (10×1018 ion decays per year per baseline), the sensitivity to θ13 reaches sin2 2θ13 ≥ 1×10−4; the sign of the atmospheric mass difference can be identified, regardless of the true hierarchy, for sin2 2θ13 ≥ 3× 10−4; and, CP violation can be discovered in 70% of the δ -parameter space for sin2 2θ1...

nosity, and isotope pair used. We identify two qualitatively different cases: θ13 not discovered at the time a decision has to be made (θ13 small), and θ13 discovered at that time (θ13 large). For small θ13, it turns out that the obtainable sensitivity is essentially a matter of the effort one is willing to spend. For large θ13, however, one can find clear optimization criteria, and one can use...

We proposed and analyzed a scheme to generate large-size Schr\"odinger cat states based on linear operations of Fock states, squeezed vacuum conditional measurements. By conducting measurements via photon number detectors, two unbalanced small-amplitude kitten combined by beam splitter can be amplified state with the same parity. According simulation results, odd amplitudes $|\ensuremath{\beta}...
