In this paper a new method is presented for particles in storage rings which
could reach a statistical sensitivity of 10**(-27) e cm for the deuteron EDM.
This implies an improvement of two orders of magnitude over the present best
limits on the T-odd nuclear forces ksi parameter.Comment: 5 pages. Proceedings of a talk presented at CIPANP 2003, May 19-24,

We are proposing a new method to carry out a dedicated search for a permanent electric dipole moment (EDM) of the muon with a sensitivity at a level of 10 −24 e · cm. The experimental design exploits the strong motional electric field sensed by relativistic particles in a magnetic storage ring 1,2 . As a key feature, a novel technique has been invented in which the g-2 precession is compensated with radial electric field. This technique will benefit greatly when the intense muon sources advocated by the developers of the muon storage rings and the muon colliders become available.
For efficient and reliable negative ion generation it is very important to improve a cesium control and diagnostics. Laser beam attenuation and resonance fluorescence can be used for measurement of cesium distribution and cesium control. Resonant laser excitation and two-photon excitation can be used for improved cesium ionization and cesium trapping in the discharge chamber. Simple and inexpensive diode lasers can be used for cesium diagnostics and control. Cesium migration along the surface is an important mechanism of cesium escaping. It is important to develop a suppression of cesium migration and cesium accumulation on the extraction system.
We are proposing a new method to carry out a dedicated search for a permanent electric dipole moment (EDM) of the muon with a sensitivity at a level of 10-24e · cm in both statistics and systematics. This will make the sensitivity of the EDM experiment to non-standard physics better than the sensitivity of the present muon g-2 experiment, assuming the CP violating phase of the probed physics is of order one. The experimental design exploits the strong motional electric field sensed by relativistic particles in a magnetic storage ring.1,2 As a key feature, a novel technique has been invented in which the g-2 precession is compensated with a radial electric field.
Simplified beam line for low energy Ion implantation is considered. Compensation of the space charge of high perveance, low energy ion beam in beam lines for ion implantation and isotope separation has been investigated. Different mechanisms of the compensating particle formation such as ionization by the beam, secondary emission of electrons and negative ions, electronegative gas admixture, and external plasma sources are discussed. Advanced space charge compensation increases an intensity of low energy ion beam after analyzer magnet up to 3-4 times. Space charge compensation of positive ion beam by admixture of electronegative gases and damping of the beam instability are discussed. Up to 6 mA of 11 B + ions with energy 3 keV, 11 mA with 5 keV, and 18 mA with 10 keV have been transported through an analyzer magnet of a high current implanter with space charge compensation by electronegative gases
