      abstract     = {The future upgrades of the European XFEL (EuXFEL) foresees
                      continuous wave (CW) and High-Duty-Cycle (HDC) operation [1]
                      requiring a CW electron photoinjector. Motivated by this, a
                      1.6-cell superconducting radio frequency (SRF) electron gun
                      cavity is under development at DESY. Recently, the DESY CW
                      SRF gun cavities out of niobium with a copper cathode
                      screwed directly to the cavity’s back wall demonstrated a
                      peak electric on an axis field of up to 55 MV/m [2]. The
                      design of the DESY gun cavity requires air-stable
                      photocathodes, limiting the choice of photocathode materials
                      to metals. Presently, copper is the baseline photocathode
                      material. However, photoinjector operation at high
                      repetition rates using a copper photocathode is challenging
                      due to laser power limitations in the UV range. Therefore,
                      we are exploring methods to enhance the quantum efficiency
                      (QE) of metallic photocathodes to allow higher repetition
                      rates. In this work, we report our current progress on
                      numerical and experimental efforts towards metal cathodes
                      with enhanced photoemissive properties.},
