Developments of the CRYEBIS Generation at Orsay

CRYEBIS 2 is completed. The project is described. Main features are: 50 keV-3.5 A decelerated electron beam, 5 T-1.6 m long superconducting solenoid at 2.3°K. The gun to reach 104 A.cm-2 has been tested, and SILFEC 3, a smaller scale model of CRYEBIS 2, has been extensively used with a CW electron beam and joined cycles up to 6 kV-1 A. The deceleration of electrons is reliable (from 10 keV to 1.8 keV) and the produc-tion of atoms of metal species by means of a laser has been tested.
