The efficiency with which a positron beam is converted into an positronium beam, via charge exchange in molecular hydrogen and argon gases was investigated. At certain incident positron energies, molecular hydrogen was found to be over three times as efficient as argon for this purpose. The beam conversion efficiency was investigated with respect to both gas pressure and energy. Preliminary measurements for the total cross section of Ps scattering from molecular hydrogen are also presented.

Initial Results

Slow Positron Beam (PB) is an important device in the study of positron physics andtechniques, especially in material research. For the purpose of conceptual designing a PB system, we have simulated a PB system with the parameters of an existing system – SPONSOR, using SIMION software. The simulation results have been compared with the SPONSOR published results. The effect of magnetic field in controlling beam trajectory has been investigated in the preaccelerated and accelerated stages. The simulation results of using steering coils to adjust the beam trajectory are also presented in this report.
