A new approach to search for CP violation in the neutrino sector [1,2] is proposed by the experiment called DAE{\delta}ALUS (Decay At rest Experiment for {\delta}cp At Laboratory for Underground Science). DAE{\delta}ALUS needs three sources…
Using H2+ ions is expected to mitigate the two major impediments to accelerating very high currents in cyclotrons, due to lower space charge at injection, and stripping extraction. Planning for peak currents of 10 particle milliamps at 800…
This report provides a first design for H2+ accelerators as the DAEdALUS neutrino sources. A description of all aspects of the system, from the ion source to the extracted beam, is provided. The analysis provides a first proof of principle…
The Decay-At-rest Experiment for delta-CP violation At a Laboratory for Underground Science (DAEdALUS) and the Isotope Decay-At-Rest experiment (IsoDAR) are proposed experiments to search for CP violation in the neutrino sector, and…
We are developing a high-current cyclotron as a driver for the IsoDAR neutrino experiment. It accelerates 5 mA H2+ to 60 MeV/amu, after which the electron is removed to produce a 10 mA, 60 MeV proton beam. The enabling innovations that…
Design studies, for accelerator modules based on an injector cyclotron and a superconducting ring cyclotron able to accelerate H$_2^+$ molecules, are presented. H$_2^+$ molecules are stripped by a foil creating a proton beam, with a maximum…

The creation of intense radioactive beams requires intense and energetic primary beams. A task force analysis of this subject recommended an acceleration system capable of 400 MeV/u uranium at 1 particle uA as an appropriate driver for such…
We investigate limits on the current of the PSI Injector II high intensity separate-sector isochronous cyclotron, in its present configuration and after a proposed upgrade. Accelerator Driven Subcritical Reactors, neutron and neutrino…
The concept of large-radius multistage coaxial cyclotrons having separated orbits is described, to generate proton beams of 120-2000 MeV energy at tens of GW pulsed and hundreds of MW in continuous beam power operation. Accelerated beam…
Investigation of neutrino oscillations and rare meson decays are main physics goals of Project X. The successful physics outcome relies on the feasibility of high-intensity neutrino and meson (K+ and \mu) beams. In order to meet this goal…
In recent years, the interest in high intensity proton beams in excess of several milli-Amperes has risen. Potential applications are in neutrino physics, materials and energy research, and isotope production. Continuous wave proton beams…

Compact H$^-$ cyclotrons are used all across the globe to produce medical isotopes. Machines with external ion sources have demonstrated average extracted currents on the order of a few mA, although reported operational numbers are…
We discuss possible acceleration scenarios and methods for a mu+ mu- collider. The accelerator must take the beams from ~100 MeV to 2 TeV within the muon lifetime (2.2 x 10**(-6) E(mu)/m(mu) uS), while compressing bunches of 10**(12) muons…
The Daedalus experiment seeks to evaluate neutrino scattering effects that go beyond the standard model. Modular accelerators are employed to produce 800 MeV proton beams at the megawatt power level directed toward a target, producing…
New low-cost, high-power proton cyclotrons open the opportunity for a novel precision search for CP violation in the neutrino sector. The accelerators can produce decay-at-rest neutrino beams located at multiple distances from a Gd-doped…
The High Intensity Proton Accelerator (HIPA) cyclotron at the Paul Scherrer Institut (PSI) delivers 590 MeV CW proton beam with a maximum power of 1.42 MW. After extraction, the beam is transferred in a 120 m long channel towards two target…
The purpose of this paper is to provoke a discussion about the right next step in accelerator-based neutrino physics. In the next five years many experiments will be done to determine the neutrino mixing parameters. However, the small…
