In February 1999 a collaboration among CERN, DESY and CEA-SACLAY has been established in order to explore the potentiality of Electro-polishing treatments to achieve high gradients with massive niobium cavities. Resorting to the good results obtained by KEK, we produced several single-cell cavities that went over 40 MV/m. As a following step we are now producing 10 single-cell cavities with a standard recipe that should lead to high gradients with a small spread in the Q values. The first "statistical" results are foreseen by summer 2000.
