� Prototype status:

� EM simulations & construction finalized

� All parts are manufactured, brazing is underway

� Prototype has “warm” dimensions

� Successful tests of the ceramic slot windows, i.e. several thermal cycles 300 K -> 77 K -> 300 K

� Next Steps:� Warm prototype finalization (brazing), RF

measurements, tuning, beam tests (at the A0-Photoinjector).
