In Jan./Feb. 2001 a first beam time on the a0+ production in the reaction pp→ d a0+ was performed using the cluster jet target at the magnetic spectrometer ANKE at COSY Jülich. One way to determine the average luminosity during this beam time is to use the elastic proton-proton scattering where the differential cross section is well known. With ANKE one of the elastically scattered proton is detected in the forward detection system. The value obtained by this method yields L=(2.70± 0.55)× 1031 s−1cm−2.
