| Abstract | Present accelerator-based slow-positron technology impinge the positrons coming out of a conversion target on a thin foil of metal (moderator) where the positrons are thermalized and then ejected from the moderator with the surface work energy of the material. This study represents a new direction in developing accelerator-based highintensity slow-positron sources. We investigate the use of RF fields to decelerate the positrons out of the target. Techniques, such as a Penning trap or moderation can then be used to get the needed thermal positrons with higher yield. Using a relatively simple beam-line scheme, our preliminary simulations showed that it could increase the final thermal positrons yield by more than 20 times. This suggests a promising future for this new method. |
