Progress Towards A Practical Multicell Positron Trap
نویسندگان
چکیده
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, including the effects of large space charge potentials and high plasma densities on: plasma heating, deterioration of confinement, and decreased efficiency of rotating electric fields in producing plasma compression. The confinement of PM plasmas displaced both radially and toward the ends of the uniform magnetic field region will also be investigated.

Recent 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 کاملSimulations of plasma confinement in an antihydrogen trap
The three-dimensional particle-in-cell 3-D PIC simulation code WARP is used to study positron confinement in antihydrogen traps. The magnetic geometry is close to that of a UC Berkeley experiment conducted, with electrons, as part of the ALPHA collaboration W. Bertsche et al., AIP Conf. Proc. 796, 301 2005 . In order to trap antihydrogen atoms, multipole magnetic fields are added to a conventio...
متن کاملTransient Antihydrogen Production in a Paul Trap
Although positrons and antiprotons have vastly different masses, we show that it is possible to store both particle species simultaneously in a Paul trap, using the space charge of the positron cloud as a trap for the antiprotons. Computer simulations confirm the validity of this new trapping mechanism. In addition, the simulations show transient antihydrogen production that manifests itself in...

Improvement of the accuracy of dosimetry in radionuclide therapy has the potential to increase patient safety and therapeutic outcomes. Although positron emission tomography (PET) is ideally suited for acquisition of dosimetric data because PET is inherently quantitative and offers high sensitivity and spatial resolution, it is not directly applicable for this purpose because common therapeutic...
متن کاملProgress Towards A Permanent Octupole Magnetic Ultra-Cold Neutron Trap for Lifetime Measurements
Current knowledge of the neutron β-decay lifetime has come under scrutiny as of late due to large disagreements between recent precise measurements. Measurements using magnetically trapped Ultra-Cold Neutrons (UCNs) offer the possibility of storage without spurious losses which can provide a reliable value for the neutron lifetime. The progress towards realizing a neutron lifetime measurement u...
