High intensity cyclotrons for neutrino physics

High Power Cyclotrons for the Neutrino Experiments Daeδalus and Isodar

DAEδALUS (Decay At rest Experiment for δcp At a Laboratory for Underground Science) has been proposed to measure the value of the CP violating phase δ through the oscillation of low energy muon antineutrinos to electron antineutrinos. With a single large detector, three accelerators at different distances enable the oscillation to be measured with sufficient accuracy. We have proposed the multi...

Cyclotrons as Drivers for Precision Neutrino Measurements

Recent Results on Simulations of High Intensity Beams in Cyclotrons

A summary of activities that envisage a source to target simulation of the PSI cyclotron complex is presented. Our aim is to gain a quantitative understanding of complex phenomena in our machines and beam lines, including three-dimensional space charge effects, beam cavity interaction, collimation, beam neutralisation and extraction mechanism. An introduction to the mathematical and computation...

Analytic fluid theory of beam spiraling in high-intensity cyclotrons

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Using a two-dimensional fluid description, we investigate the nonlinear radial-longitudinal dynamics of intense beams in isochronous cyclotrons in the nonrelativistic limit. With a multiscale analysis separating the time scale associated with the betatron motion and the slower ...

HIGH INTENSITY CYCLOTRONS FOR RADIOISOTOPE PRODUCTION or THE COMEBACK OF THE POSITIVE IONS

High current cyclotrons are needed for the production of radioisotopes for nuclear medicine or for radiotherapy. Another application of high current cyclotrons is the production of 99mTc, either directly or as a fission product in a cyclotron-driven subcritical neutron source. The first cyclotrons for radioisotope production were classical, positive ions accelerators with E.S.D. extraction. The...
