Press
Release (10 March 2010)
A high-voltage dc photocathode electron gun (500kV gun 1st) was
successfully conditioned up to a voltage of
550 kV and a long-time holding test for 8 h was demonstrated at an
acceleration voltage of 500 kV. It is a worldrecord as accelerating
voltage of Photo-cathode DC electron gun.
