We report the design and preliminary test results of a C-14 beam monitor developed for the online monitoring for radiocarbon dating. The challenge of the INFN CHNet-Lilliput experiment is to measure the amount of carbon in very small samples (down to a few micro-grams) with a very low concentration of radiocarbon. For this purpose, a new dedicated beam monitor for C-14 ions (Energy similar or equal to 10 MeV) uses a silicon solid state detector made of 4 independent sectors, active area 50 x 50 mm(2) and 300 mu m thickness. The detector was preliminary tested in the INFN Laboratory of Bari and then installed on the final part of the Accelerator Mass Spectrometry (AMS) beam line at the INFN-LABEC Laboratory of Firenze (Italy) where sample measurements for radiocarbon dating are performed since 2004.

Abstract

We report the design and preliminary test results of a C-14 beam monitor developed for the online monitoring for radiocarbon dating. The challenge of the INFN CHNet-Lilliput experiment is to measure the amount of carbon in very small samples (down to a few micro-grams) with a very low concentration of radiocarbon. For this purpose, a new dedicated beam monitor for C-14 ions (Energy similar or equal to 10 MeV) uses a silicon solid state detector made of 4 independent sectors, active area 50 x 50 mm(2) and 300 mu m thickness. The detector was preliminary tested in the INFN Laboratory of Bari and then installed on the final part of the Accelerator Mass Spectrometry (AMS) beam line at the INFN-LABEC Laboratory of Firenze (Italy) where sample measurements for radiocarbon dating are performed since 2004.
