Physical and chemical testing of graphite targets — •Matthias Schindler, Wolfgang Kretschmer, Alexander Stuhl, Alexander Tschekalinskij und Andreas Scharf — Uni Erlangen-Nürnberg, Physikalisches Inst. Abt. IV, 91058 Erlangen

One way to reduce the background in radiocarbon AMS is to reduce the contend of hydrocarbons in the target material. Therefore we did physical tests like thermogravimetric analysis and molecular spektroscopy to determine the composition of graphite targets. Based on this results the reduction parameters were adjusted and cross checked.
