Sumario:Measurements were performed with 2 LYSO bars and 6 WLS strips mounted with the same topological configuration used for the AX-PET demonstrator. The main purposes of the measurements were threefold: (1) to investigate the influence of operational parameters (threshold, gain), (2) to study the effect of the surface property of a screen behind the WLS strips on the photoelectric yield and cluster multiplicity of the WLS strips, and (3) to measure the dependence of the WLS strip response on the gamma energy.
