High Power Polarized Positron Source

Abstract

Abstract. We discuss the basics of polarized positron production by low energy polarized electrons. Efficiency of conversion ~0.1-1% might be interesting for CEBAF facility and ILC as well.

Feasibility and conceptual design of a C.W. positron source at CEBAF

“…The equivalent power is calculated on the assumption of 126 MeV electron beam with 10 mA current impinging on a 2 mm thick tungsten target, which is 1260 kW of incoming beam power. A liquid jet target which is made of mercury [46] or liquid Bi-Pb [57] as shown in Fig. 87 has also been proposed as target alternatives for ILC.…”
