We have performed two proton-proton bremsstrahlung experiments below the pion production threshold. The main goal of these experiments is to study aspects of the nucleon-nucleon interaction, which cannot be extracted from elastic scattering [1]. These experiments have been performed with the 190 MeV polarized-proton beam of the AGOR cyclotron at KVI. Outgoing protons were detected with the newly built Small-Angle Large-Acceptance Detector (SALAD). For the detection of the bremsstrahlung photons we used the Two-Arm Photon Spectrometer (TAPS) in two different geometries. We have measured absolute cross sections and analyzing powers of the pp-bremsstrahlung reaction in a large part of phase space, with a very high statistical accuracy. The results will be presented in comparison with theoretical predictions.
