EPICS Based Control System for SPES Tape Station for Beam Characterization: Motion System and Controls

Abstract

International audienceThe SPES* Tape Station (STS) for Radioactive Ion Beams (RIBs) characterization is under construction at LNL. This tool will be used to measure the actual composition of the radioactive ion beams extracted from the SPES-β ion source and to optimize the source’s parameters. STS will provide beam diagnostic information by determining the beam composition and intensity. At the same time, it will be able to measure the target release curves needed for the source’s characterization and development. The core part of the system, the related motor and controls are being designed and constructed in synergy with IPN Orsay (France), iThemba Laboratories (South Africa) and the Gamma collaboration (INFN-CSN3). In particular, the mechanical part is based on the existing BEDO** tape system operated in ALTO while the control system for motion is an EPICS*** base application under implementation by iThemba and INFN, result of a upgrade operation required to substitute obsoleted hardware and update logic and algorithm
