Alexis Brossard

The TRIUMF UltraCold Advanced Neutron (TUCAN) collaboration aims for the measurement of the neutron electric dipole moment (nEDM) with a one order of magnitude improvement of the current best limit. Ultra-cold neutrons (UCNs) suits for such experiment as they can be trapped and stored for several minutes. The collaboration works toward the completion of a new high-intensity UCN source. UCN are...

Shyh-Yuan Lee

10/05/2023, 11:10

We study the feasibility of storing cold neutron beams in a strong focusing synchrotron. We also propose an alternating-current (AC) dipole magnet to be used as a neutron acceleration device, and a pulsed quadrupole as a neutron beam kicker for injection and extraction. The AC acceleration device can provide adiabatic capture, acceleration or deceleration of neutron beams. It seems feasible to...
