Stable beam operation of approximately 1 mA beam under high-efficient energy recovery condition at compact ERL

H. K. Sakai, D. Arakawa, Nishimori Nobuyuki, Hajima Ryoichi et autres

A compact energy-recovery linac (cERL) has been constructed at KEK since 2009 to develop the key technologies of the energy-recovery linac. The cERL has been started operating since 2013 to create the high current beam with a low emittance beam with CW …

Three-phase UPS transformer using stand-by inverter of a single cores

Kazuo Bessho, Sotoshi Yamada, K. Harada

A new three-phase UPS transformer for an uninterruptible power supply (UPS) is described. Its configuration is a magnetic integration of a three-phase ferroresonant transformer and a single- to three-phase converter. The three-phase commercial source takes over a load on normal condition. The …
