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...

High efficiency positron accumulation for high-precision magnetic moment experiments.

Positrons are accumulated within a Penning trap designed to make more precise measurements of the positron and electron magnetic moments. The retractable radioactive source used is weak enough to require no license for handling radioactive material, and the radiation dosage 1 m from the source gives an exposure several times smaller than the average radiation dose on the earth's surface. The 10...

High efficiency magneto-optical trap for unstable isotopes

We have trapped over 250 000 Fr in a new on-line high efficiency magneto-optical trap ~MOT!. We describe the new apparatus and present an overview of high-efficiency MOTs for trapping rare isotopes. These traps depend on three critical components: a dry-film coating, a neutralizer, and the optical trap. We have developed a series of independent tests of the effectiveness of these components, an...

Progress 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...

Efficiency of antlion trap construction.

Assessing the architectural optimality of animal constructions is in most cases extremely difficult, but is feasible for antlion larvae, which dig simple pits in sand to catch ants. Slope angle, conicity and the distance between the head and the trap bottom, known as off-centring, were measured using a precise scanning device. Complete attack sequences in the same pits were then quantified, wit...
