Dear Colleagues on May 13, 14.00 at WGBG 021

Daniel Winklehner will talk about

Accelerator design and modeling for the decay-at-rest neutrino experiments DAEδALUS and IsoDAR

Abstract:

The proposed Decay-At-rest Experiment for δCP violation At the Laboratory for Underground Science

(DAEδALUS) and the Isotope Decay-At-Rest experiment (IsoDAR), search for CP violation in the neutrino

sector and sterile (non-interacting) neutrinos. Both are short baseline experiments that use proton driver

beams. In the IsoDAR case, a 60 MeV proton beam will impinge on a high purity lithium/beryllium target

to produce isotope decay-at-rest and in DAEδALUS, 800 MeV protons will hit a carbon target to produce

pion/muon decay-at-rest. The drivers are cyclotrons, because they are comparatively cheap, compact and

deliver the highest intensities in the considered energy range. In order to obtain the necessary high

neutrino fluxes, the primary proton beam current needs to be even higher than current state-of-the-art

machines at PSI have demonstrated. This has led to a substantial R&D effort on the accelerator side of

DAEδALUS and IsoDAR. In this contribution, we will report on the latest driver designs and the challenges

we are faced in creating, transporting, and accelerating high intensity beams.

Later he will give this talk at the occasion of the Groupement de Recherche (GDR)  Neutrino Meeting in Paris.

Please mark you calendar for June 3, Pirmin Berger (Summer Student) will give his final presentation (Towards a Particle Core Model for Cyclotrons).

Cheers

Andreas
