Abstract :
The 2 GeV electron linac at the Pohang accelerator laboratory (PAL) has been operated continuously as a full energy injector since its completion on December 1994. The linac system has been continuously upgraded to improve overall system stability and reliability, as well as to increase final injection energy to 2.5 GeV. Eight klystron tubes out of 11 tubes have survived since the beginning of linac operation. The average high voltage operation time of the surviving klystrons (E-3712, Toshiba) has been reached near 35,000 hours as of December 1998. Current overall system availability is well over 90%. In this paper, we report the major linac system performance as well as relevant machine statistics, the electron beam parameter measurement, and operational characteristics of cooling water system
