Abstract
NEPOMUC, operated by the Technische Universität München and the Universität der Bundeswehr München, provides a high-intensity low-energy positron beam for applications in solid state and surface physics as well as for fundamental research in nuclear and atomic physics. The intensity amounts to > 109 moderated positrons per second at a beam energy of E = 1 keV.
Highlights
At NEPOMUC, the positrons are generated by pair production from absorption of high-energy prompt gamma-rays after thermal neutron capture in cadmium (Cd) (Hugenschmidt et al, 2008)
The remoderation device of NEPOMUC (Piochacz et al, 2008) enhances the brightness of the positron beam and enables positron experiments which are highly resolved in space or/and in the time domain
There are experiments which do not depend on a high phase space density but need the full intensity of the primary beam
Summary
At NEPOMUC, the positrons are generated by pair production from absorption of high-energy prompt gamma-rays after thermal neutron capture in cadmium (Cd) (Hugenschmidt et al, 2008). 2.1 Key values of the primary positron beam Intensity: > 109 moderated positrons per second
