Abstract

A hybrid positron-source scheme based on an electron beam of the Sorgente Pulsata e Amplificata di Radiazione Coerente test facility installed at the Laboratori Nazionali di Frascati (Frascati, Italy) is proposed. In the case of a thin (0.1-mm-thick) amorphous converter, the positron yields per primary electron are compared at positron energies of 1–3 MeV under bremsstrahlung generation and (110)-plane channeling conditions. The radiation of 200-MeV electrons (200 MeV is the parameter of the SPARC accelerator at the LNF) channeled in a 10-µm-thick tungsten radiator is demonstrated to create positron yields of 104–105 s–1 in a 0.1-mm-thick W converter.
