  In order to investigate and understand the influence of gun design, cathode
preparation and operational parameters on the beam quality it is important to
have reliable and accurate beam diagnostics available. The focus of this work
was thus to employ the available diagnostic beam line of the current gun
demonstrator to characterize the transverse phase space of the beam and measure
the emittance at various beam settings and operation conditions. Slit mask and
solenoid scanning techniques are applied.
