Can LHC physics shed light on the neutrino paradigm?I argue that LHC may shed light on the nature of neutrino mass through the probe of the seesaw mechanism. The smoking gun signature is lepton number violation through the production of same sign lepton pairs, a collider analogy of the neutrinoless double beta decay. I discuss this in the context of L-R symmetric theories, which predicted neutrino mass long before experiment and led to the seesaw mechanism. A WR gauge boson with a mass in a few TeV region could easily dominate neutrinoless double beta decay, and its discovery at LHC would have spectacular signatures of parity restoration and lepton number violation. I also discuss the collider signatures of the three types of seesaw mechanism, and show how in the case of Type II one can measure the PMNS mixing matrix at the LHC, complementing the low energy probes. Finally, I give an example of a simple realistic SU(5) grand unified theory that predicts the hybrid Type I + III seesaw with a weak fermion triplet at the LHC energies.Speaker: Goran Senjanovic (ICTP, Trieste)

WG3 Performance Comparison Between FSIIA and Bucked Coils for the Neutrino Factory Cooling LatticeThe transverse emittance of the muon beam produced at the Neutrino Factory front-end needs to be decreased using ionisation cooling. The current baseline cooling lattice for the Neutrino Factory, FSIIA, achieves acceptable muon transmission and transverse emittance reduction. However, recent studies indicate that high magnetic field at the position of the RF cavities may limit their maximum achievable gradient, and, since the magnetic field at the RF position of FSIIA is large, the feasibility of this lattice has come under question. A new lattice, Bucked Coils, was designed obtaining four times lower magnetic field than FSIIA while also achieving comparable transmission within 30 mm of transverse acceptance. A detailed comparison between the two lattices is presented with respect to the beam dynamics and the magnetic field.Speaker: Ms Androula Alekou (Imperial College London)

Recent Studies on the PRISM FFAG RingNext generation lepton flavour violation experiments require high intensity and high quality muon beams. The PRISM task force focuses on accelerator R&D for realizing such beams using an FFAG ring. The scaling and non-scaling designs for the PRISM FFAG ring are discussed. The recent studies on injection/extraction systems and matching to the solenoid channel are outlined. The future plans for the study are presented.Speaker: Dr Jaroslaw Pasternak (Imperial College, London)

First measurements of muon production rate using a novel pion capture system at MuSICThe MuSIC (Muon Science Innovative Channel) beam line at RCNP (Research Centre for Nuclear Physics, Osaka) will be the most intense source of muons in the world. A proton beam is incident on a target and, by using a novel capture solenoid, guides the produced pions into the beam line where they subsequently decay to muons. This increased muon flux will allow more precise measurements of cLFV (charge Lepton Flavour Violation) as well as making muon beams more economically feasible. Currently the first 36$^{circ}$ of solenoid beam pipe have been completed and installed for testing with low proton current of 1nA. Measurements of the total particle flux and the muon life time were made. The measurements were taken using thin plastic scintillators coupled to MPPCs (Multi-Pixel Photon Counter) that surrounded a magnesium/copper stopping target. The scintillators were used to record which particles stopped and their subsequent decay times.Speaker: Mr Sam Cook (UCL)

Neutrino Factory Front End and ExtensionsThe (International Design Report) IDR neutrino factory scenario for capture, bunching, phase-energy rotation and initial cooling of mu’s produced from a proton source target is presented. It requires a drift section from the target, a bunching section and a phase-energy rotation section leading into the cooling channel. The rf frequency changes along the bunching and rotation transport in order to form the mu’s into a train of equal-energy bunches suitable for cooling and acceleration. Optimization and variations are discussed. Important concerns are rf limitations and beam losses; mitigation procedures are described. Extensions of the method for a muon collider front end and bunch combiner are discussed.Speaker: David Neuffer (Fermilab)

A new lattice for the beta-beam decay ring to enlarge the stability limitThe beta-beam concept relies on the production, by beta decay of radioactive ions of a very high flux, of an electron neutrino and anti-neutrino beam towards a distant detector. After production and acceleration in an accelerator complex consisting of a rapid cycling synchrotron, the CERN PS and the CERN SPS, the radioactive isotopes are injected into a long racetrack-shaped ring, called the decay ring, where they orbit until they decay or are lost. The required intensities to store in the decay ring to reach the aimed neutrino fluxes are very high. Among the collective effects, the head tail effect, caused by transversal resonance impedance, is one of the main issues: the beam was shown to be unstable with the previous decay ring lattice. To mitigate these effects, we reduced the transition gamma by removing the injection from the arc to put it in a chicane located in one of the long straight sections. To make an amplitude detuning by inserting octupoles in the lattice could increase the stability limit. But the cost is a reduction of the dynamic aperture. After presenting the new lattice with a smaller transition gamma, we shall discuss about the needed octupoles for an amplitude detuning and their impact on the dynamic aperture.Speaker: Dr Jacques Payet (CEA, IRFU, SACM)

Recent developments on the muon Non-Scaling FFAG for the Neutrino Factory and its subsystemsThe current status and new developments on the muon Non Scaling FFAG for the Neutrino Factory studied in the framework of the EUROnu/IDS-NF projects are presented. The beam dynamics in the presence of magnet errors, misalignments including the process of acceleration is discussed. The conclusions on the magnet and alignment tolerances are drawn. The progress on the machine subsystems like main magnets and injection/extraction is discussed. The future plans for the study are given.Speaker: Dr Jaroslaw Pasternak (Imperial College, London)

High Tc superconductor magnet technology for FFAG acceleratorsRecent developments of high Tc coated superconductor ((RE)BCO coated conductor) lead to the possibilities of very high field magnets operated at low temperature (~4.2 K) and efficient magnets operated at high temperature (several tens of Kelvin). For accelerator applications, however, the use coated conductors has been considered difficult due to their tape shape. A project funded by Japan Science and Technology Agency is in progress to challenge the difficulties and to develop the fundamental technologies of accelerator magnets using high Tc superconductors under close collaboration between Japanese university / national laboratories and industry. The primary applications are FFAG accelerators for carbon cancer therapy and those for accelerator-driven subcritical reactor. First, the overview of the project is summarized, and, then, recent results of research and development on several key issues for applications of high Tc superconductor tapes to magnets for FFAG accelerators are presented. This work was supported by Japan Science and Technology Agency under Strategic Promotion of Innovative Research and Development Program.Speaker: Naoyuki Amemiya (Kyoto Univ.)
