Potential well distorsion lengthening was measured at different bunch currents for the energies below 500 MeV. First measurements reveals the presence of microwave instabilty with turbulent emittance growth. The thresholds of these processes was used to estimate the values of reactive part of the longitudinal impedance. Measured energy loss factors was compared with computer simulations for the RF cavity. All results will be discussed and further estimations will be given.
