Erice: INTERNATIONAL SCHOOL OF NUCLEAR PHYSICS, 47th COURSE

The PTOLEMY project exploits the innovative concept of the transverse drift filter, in which the synergic action of on uniform magnetic field and electric one play a key role. This is used to achieve a controlled reduction of the kinetic energy of electrons within a one-meter transport length. Before implementing this approach in the PTOLEMY demonstrator, a proof-of-principle test will be carried out. To this aim, a cylindrical Halbach permanent magnet — capable of generating a 1 T dipolar magnetic field orthogonal to the cylinder axis inside the hollow — can be employed together with an electron gun as the particle source. The design of the experimental setup and dedicated simulations are presented in this talk.
