Commissioning of the ERDA-TOF beamline at the ion beam laboratory in Madrid

Abstract

We report progress for the ERDA time-of-flight beamline at the Centre of Micro-Analysis of Materials in Madrid. This beamline experienced a long shut down and has recently gone through a re-commissioning process. The time stations, based on a twin mirror design, demonstrate a time resolution of 215 ps for 6 MeV He2+. Using a standard particle detector for the energy signal we find a mass resolution of 1.4 atomic mass units for 27Al and 28Si with 40 MeV Cl4+. Detection efficiency needs no corrections for elements heavier than 7Li. Analysis of a borosilicate reference showed good agreement with the known composition. Based on these results, the facility is considered operational and open for users.
