Abstract

At the SORTEC 1-GeV SR source facility for the study of X-ray lithography, the upgrade of the stored beam current to over 500 mA was performed. The RF cavity power supply was increased from 14 kW to 28 kW together with modification of the RF coupler. In addition, the pumping system and the cooling capacity of the storage ring were also reinforced. Reconstruction work and beam tests for upgrade were carried out for 3 months beginning April ´92. A stored beam current of 500 mA was successfully achieved within only 2 weeks after the beam operation was restarted. At present the lifetime has reached 25 h. These results are discussed from the aspects of the key issues for upgrading of the stored current and the SR beam aging effects on the time-evolution of the lifetime
