Abstract
The Vienna Environmental Research Accelerator (VERA) is a 3-MV Pelletr on tandem mass spectrometer system. Since July 1996, extensive tests w ith Al-26 detection were performed. Systematic investigations of repro ducibility, transmission, overall efficiency etc. are necessary for a new facility such as VERA in order to come up with reliable results. T o this end several different Al-26 standards with an Al-26/Al-27 isoto pic ratio between 5 x 10(-10) and 1 x 10(-12) were used. The results o f these investigations revealed no systematic deviation beyond countin g statistics. In order to determine the cross section for the Al-27(n, 2n)Al-26 reaction Al-metal samples with Al-26 produced from neutron ir radiation were measured and compared with Al-26 standards.
