| THXB01 | Interaction of Muon Beam with Plasma Developed During Ionization Cooling | 3200 |
|
||
| Muon collider has been envisioned as a future high energy lepton machine. High luminosity can be obtained by the ionization cooling – best suited for muons due to their short life time. In this cooling process, particles ionize material medium in which they lose momentum, thus the normalized emittance is reduced. The ionized medium is called plasma and the ionization density could increase due to the passage of multiple bunches through the material. This means that the incoming beams interact with plasma together with ionizing the medium used for cooling. It is, therefore, important to investigate the effects of background plasma on the incoming bunches. A comprehensive studies of muon beam propagation through plasma medium using EM particle-in-cell simulations. This computational study involves kinetic model, therefore, provides deep insight of the phenomena, which cannot be obtained by the conventional fluid model. The wakes excited by mu+ and mu- are different due to the beam polarity and depends on their relative densities. Externally applied axial magnetic field suppresses the wakes evolved during the interaction. The details of this study will be discussed in the paper. | ||

Experimental Demonstration of Suppressing Coherent Synchrotron Radiation | |
|
||
| This presentation should discuss the first successful demonstration of suppressing both the energy loss and energy spread caused by coherent synchrotron radiation in a bending magnet using polished parallel Al plates. The results of measurements should be compared with exact analytical calculations and with simulation results. | ||

| THXB03 | Beam and Spin Dynamics in an Electric Proton EDM Ring | 3203 |
|
||
| Electric dipole moment (EDM) measurements may help to answer the question ‘‘Why is there more matter than anti-matter in the present universe?'' For a charged baryon like the proton such a measurement is thinkable only in a ring in which a bunch of protons is stored for more than a few minutes, with polarization ‘‘frozen'' (relative to the beam velocity) and with polarization not attenuated by decoherence. Beam and spin dynamics in an all-electric lattice with these characteristics is described. Rings for other charged baryons, such as deuterons or helium-3 nuclei, are also possible but, requiring both electric and magnetic fields, they are more complicated. | ||
