Abstract
We report recent progress in the development of a hybrid lead/niobium superconducting RF (SRF) photoinjector. The goal of this effort is to produce an injector with the SRF properties of a niobium cavity along with the superior quantum efficiency (QE) of a lead photocathode. Quantum efficiency measurements have been performed on an RF cavity with an electroplated lead plug as the photocathode. The effect of the laser on the RF performance of the cavity was characterized. Further measurements of the cavity RF performance are reported in these proceedings [6].
