Description

The seminar will provide a broad overview of the AIST accelerator based positron facility, including the development of a microbeam for positron annihilation lifetime spectroscopy (PALS); the positron probe microanalyzer (PPMA). A second, slow positron beamline has also recently been installed at AIST and is dedicated to PALS measurements. In particular, the seminar will focus on plans for a superconducting accelerator (SCA) for slow positron production at AIST. An overview of the SCA project and the current status will be presented. In addition, Monte-Carlo simulations of slow-positron production from electron accelerators will be introduced and used to estimate the yield of slow positrons based on the projected SCA parameters.
