MOZMH03	Search for the Charged Particle Electric Dipole Moments in Storage Rings	lattice, dipole, polarization, storage-ring	6
	V. Senichev FZJ, Jülich, Germany
	The idea of searching for the electric dipole moment (EDM) of proton and deuteron using polarized beams in a storage ring was originally proposed at Brookhaven National Laboratory (BNL), USA. Currently, the Jülich Electric Dipole moment Investigations (JEDI) collaboration develops the conceptual design of such a ring specifically for the search of the deuteron electrical dipole moment (dEDM). The idea is that the oscillation of the spin due to a possible finite electric dipole moment is separated from the influence of the magnetic dipole moment (MDM), and the spin behavior indicates the existence of dEDM. In connection with this problem, two questions arise: (i) how to create conditions for maximum growth of the total EDM signal of all particles in the beam bunch, and (ii) how to differentiate the EDM signal from the induced MDM signal. For the design of such a ring, we need to address three major challenges: - the ring lattice should meet the conditions of beam stability, and it has to have incorporated straight sections to accommodate the accelerating station, equipment for injection and extraction of the beam, a polarimeter, and sextupoles; - the polarization lifetime of the beam must be around ~1000 seconds; - systematic errors have to be minimized to eliminate the induced fake EDM signal. In my contribution, I will present the current status of the project.

	An increasing number of proton therapy facilities are being planned and built at hospital based centers. Many facilities use rotatable gantry beamlines to direct the proton or ion-beam at the patient from different angles. A key issue is the need to make future gantries lighter and more compact with the use of cryogen-free superconducting magnets, in particular for the final bending section which can be of large aperture. Benefits of using the superconducting technology are: (1) the possibility to have a large momentum acceptance, hence reducing the need to ramp the magnet and enabling new treatment techniques, (2) the size reduction due to a lower bend radius and (3) the weight reduction up to a factor ten. The latter will also significantly reduce the costs of the supporting structure. We present a conceptual design based on Nb3Sn superconducting combined function magnets (dipole, quadrupole, sextupole). The geometry using racetracks, the superconducting strand and cable parameters and the results of the thermal and the mechanical studies are reported. These magnets will work at a temperature of about 4.2 K cooled with cryocoolers.
