Recently, user experiments with a bunch charge of 100 pC and beam transport experiments with 200 pC have been performed. The electron beam diagnostics will be presented, including the slit-scan measurements of the transverse phase space, the quadrupole-scan emittance measurement and the phase-scan bunch length measurement. Principles and results of these diagnostics will be introduced, as well as the error analysis. A UV laser is used to emit electron, the pulse length of which directly impacts the electron beam. A commercial cross correlator has been installed to measure the temporal profile of the UV laser. The alignment of the beam measurement results for this will be presented. Bases on the operation experiences from the current SRF gun, a new gun-lab has been proposed to build and test the next SRF gun in a separated room from the ELBE accelerator. The preliminary design of a new corresponding diagnostics beamline will be presented, featuring a fast beam-scan transverse phase space measurement and a transverse deflecting structure based measurement of longitudinal phase space.
