Beta-decay spectroscopy of the $^{187}\mathrm{Ta}$ ground state was performed at KEK Isotope Separation System. $\ensuremath{\beta}$-delayed $\ensuremath{\gamma}$ rays corresponding to previously reported in-beam transitions were observed. The $\ensuremath{\beta}$-decay half-life determined be 283(10) s by analyzing a time spectrum $\ensuremath{\beta}\text{\ensuremath{-}}\ensuremath{\gamma}$ co...

The physics potential of beta beams is investigated from low to very high gamma values and it is compared to superbeams and neutrino factories. The gamma factor and the baseline are treated as continuous variables in the optimization of the beta beam, while a fixed mass water Cherenkov detector or a totally active scintillator detector is assumed. We include in our discussion also the gamma dep...

Where L is the luminosity in units 10cm s s , r is the beam aspect ratio at the collision point, Ebeam the beam energy in GeV, v the beam-beam tune shift parameter, ? v the beta function at collision point and Ibeam is the average single beam current in amperes. Our strategy for increasing L is described in reference [1]; here we will reiterate the main points. Provided the single bunch current...

A very simple pinhole camera set-up has been built to diagnose the electron beam emittance of the ESRF. The pinhole is placed in the air next to an Al window. An image is obtained with a CCD camera imaging a fluorescent screen. The emittance is deduced from the size of the image. The relationship between the measured beam size and the electron beam emittance depends upon the lattice functions a...

EB (electron beam) irradiation of sulfonamide within a beta-cyclodextrin (beta-CD) inclusion complex in the solid state induced the solvent-free Fries rearrangement, which proceeded at a shorter reaction time with reversed regioselectivity by inclusion into the beta-CD, compared with that of sulfonamide crystals; the beta-CD as a restricted nanospace had a large effect on the reactivity and reg...

A high intensity source of a single neutrino flavour with known spectrum is most desirable for precision measurements, the consensus direction for the future. The beta beam is an especially suitable option for this. We discuss the prospects of a very long baseline beta beam experiment with a magnetized iron calorimeter detector. We observe that this experiment is well suited to determine the si...

To allow the possible installation of a 2 Insertion Device in the CAMD Light Source, the lattice optic needs to be changed. The present configuration has a small vertical beta function in the long straight section containing the 7 Tesla wiggler. The new optic will give a small vertical beta at two long straight sections which are diametrically opposite. Test results with the new optic are prese...

Introduction The International scoping study of a future Neutrino Factory and Super-beam Facility (ISS) was established at NuFact 05 to survey the possibilities available for a future complex for precision neutrino physics to succeed the super beam experiments (T2K in Japan and Noνa in the USA) currently under construction. The possibilities centre around developments of the superbeam concept w...
