Abstract
The RadPhi Collaboration has proposed the use of the intense tagged photon beam in Hall B at TJNAF to produce φ mesons and measure the branching ratios of φ’s decaying into the a0(980)γ and f0(980)γ all-neutral final states. The comparison of branching ratios for these two decay modes should provide crucial information on the quark substructure of a0(980) and f0(980) scalar mesons. Three engineering runs conducted so far measured the photon beam profile, instantaneous rates, pileups and dead times in the detector components, as well as energy and timing resolutions of RadPhi detectors. The measurements demonstrated that the proposed experiment is capable of detecting rare radiative φ decays with branching ratios greater than 10−5 .
