post-harvest management of potatoes is a major challenge in iran. approximately 30% of the harvest is lostafter a few months of storage. the chemical methods for long term storage are not adequate to controldeterioration and also produce undesirable side effects. to address this issue, a study on radiationpreservation of potatoes was carried out. agria potato bulbs were irradiated using beta be...

Realistic calculation of NLC luminosity has been performed using particle tracking in DI-MAD and beam-beam simulations in GUINEA-PIG code for various values of beam emit-tance, energy and beta functions at the Interaction Point (IP). Results of the simulations are compared with analytic luminosity calculations. The optimum range of IP beta functions for high luminosity was identified. Abstract ...

In the future neutrino experiments, a beta-beam, which can produce pure electron neutrino beam, is expected to achive precise measurement of the neutrino oscillation parameters. In the νμ appearance measurement of a beta-beam, a detector does not need to identify particle charge and thus, a water Cherecov detector will be a candidate for the far detector. In this paper, we study the expected si...

The recent discovery of neutrino oscillations, has implications for the Standard Model of particle physics. Knowing the contribution of neutrinos to the Standard Model, needs precise measurements of the parameters governing the neutrino oscillations. The EUROnu Design Study (European Commision FP7 program) will review three facilities (the so-called Super-Beams, Beta Beams and Neutrino Factorie...

We discuss the minimum requirements for a neutrino beta beam if θ13 is discovered by an upcoming reactor experiment, such as Double Chooz or Daya Bay. We require that both neutrino mass hierarchy and leptonic CP violation can be measured to competitive precisions with a single-baseline experiment in the entire remaining θ13 range. We find that for very high isotope production rates, such as the...

We present an empirical analytic approximation for the luminosity \de-enhancement" factor HD in e e collisions, as a function of the disruption parameters Dx, Dy, the hour-glass parameters Ax, Ay, and the beam aspect ratio R x= y. We treat Gaussian beams with essentially arbitrary aspect ratio, assuming only that the vertical beam size is less than or equal to the horizontal beam size and that ...
