AB  - We  report  on  the  status  of  an  electron  RF-gun  made  of  two  superconductors:  niobium  and  lead. The presented design combines the advantages of the RF performance of bulk niobium superconducting cavities and the reasonably high quantum efficiency of lead, as compared to other  superconducting  metals.  The  concept,  mentioned  in  a  previous  paper,  follows  the  attractive  approach  of  all  niobium  superconducting  RF-gun  as  it  has  been  proposed  by  the  BNL  group.  Measured  values  of  quantum  efficiency  for  lead  at  various  photon  energies,  analysis  of  recombination  time  of  photon-broken  Cooper  pairs  for  lead  and  niobium,  and  preliminary cold test results are discussed in this paper.
