Trap-based positron beams
Large numbers of positrons can be accumulated and cooled in a Penning-type trap. These positron clouds can be manipulated and conditioned using plasma physics techniques, before being released from the trap to form high quality positron beams. These techniques offer a qualitatively new method for positron beam formation and manipulation that has significant advantages in efficiency, flexibility...
متن کاملProgress Towards A Practical Multicell Positron Trap
Described here is progress in an experimental program to develop a 21 cell multicell trap for the accumulation and storage of ~ 10 positrons. The basic architecture is an arrangement of multiple Penning-Malmberg (PM) trapped plasmas (i.e., cells) arranged in parallel in a common vacuum system and magnetic field. Experiments are described that are intended to address several key issues, includin...
متن کاملRecent Progress in Tailoring Trap-based Positron Beams
Recent progress is described to implement two approaches to specially tailor trapbased positron beams. Experiments and simulations are presented to understand the limits on the energy spread and pulse duration of positron beams extracted from a Penning-Malmberg (PM) trap after the particles have been buffer-gas cooled (or heated) in the range of temperatures 1000 T 300 K. These simulations are ...
متن کاملLocation as a Poverty Trap
In this paper, we ask “Can proximity to towns reduces poverty in rural areas?” For this study we have mapped all the villages in Orissa. The study is based on small area poverty estimation methodology as well as the secondary data covering 47,395 villages and 109 towns. Our main findings are (i) there is a relationship between the distance to nearest town and rural poverty and (ii) poverty leve...
متن کاملA positron trap and beam apparatus for atomic and molecular scattering experiments.
An instrument has been designed and constructed to provide new insights into fundamental, low energy positron scattering processes. The design is based on the Surko trap system and produces a pulsed positron beam with an energy resolution of as good as 54 meV. The design and operation of the apparatus is explained, while the first experimental results from this apparatus have been demonstrated ...
