23. Testing Fuel Polarization Survivability in a Tokamak Plasma

Dr Xiangdong Wei (Jefferson Lab)

The cross section of the primary reaction in a tokamak fusion reactor, D + T --> α + n, would be increased by 50% if the fuels were fully polarized along the local magnetic field. In a large-scale fusion reactor such as ITER, the power gain could be as much as 75% due to increased alpha heating. Such a boost would be a significant step towards establishing a burning plasma. The...

The first direct measurement of charged particle Electric Dipole Moment (EDM) was performed by the Jülich Electrical Dipole Moment Investigations (JEDI) collaboration. These investigations were carried out using polarized deuteron beams at the COoler SYnchrotron (COSY) located at the Forschungszentrum Jülich in Germany. The search for an EDM demands high precision measurements, separating the...

3. A versatile bulk superconducting MgB$_2$ cylinder for the production of holding magnetic field for polarized targets and nuclear fusion fuels

Giuseppe Ciullo (Dipartimento di Fisica e SdT Università di Ferrara and INFN sez. di Ferrara - Ferrara)

A versatile solution is being pursued for the challenging magnetic problem of producing internal fields in compact spaces. It is a promising tool for trapping fields around a polarized target, while shielding out external fields from spectrometers, and in addiction, for generating holding fields for accumulation and transport of polarized fuel in nuclear fusion tests.
The bulk...

30. Simulations of Beam Losses for the Prototype EDM Ring

Mr Saad Siddique (IKP Forschungszentrum Jülich Germany, 3b Physikzentrum RWTH Aachen Germany, GSI Helmholtzzentrum für Schwerionenforschung GmbH Darmstadt Germany)

28/09/2022, 09:30

The matter-antimatter asymmetry may be explained through CP-violation by observing a permanent electric dipole moment (EDM) of subatomic particles. An advanced approach to measure the EDM of charged particles is to apply a unique method of "Frozen spin" on a polarized beam in an accelerator. To increase the experimental precision step by step and to study systematic effects, the EDM experiment...

31. Optimization of spin-coherence time for electric dipole moment measurements in a storage ring

Rahul Shankar

28/09/2022, 10:00

The JEDI experiment is dedicated to the search for the electric dipole moment (EDM) of charged particles using storage rings, which can be a very sensitive probe of physics beyond the Standard Model. In order to reach the highest possible sensitivity, a fundamental parameter to be optimized is the Spin Coherence Time (SCT), i.e., the time interval within which the particles of the stored beam...
