Progress of PLS 2-GeV linac

Pohang Accelerator Laboratory (PAL) is constructing the 2-GeV Pohang Light Source (PLS). The 2-GeV electron linear accelerator will be used as a full energy injector to the storage ring. There are 42 accelerating columns in the 150-m long linac. The linac is powered by 11 klystrons of 80-MW maximum output power, which are driven by 200-MW modulators. Two 200-MW modulators connected to the klystrons are already under normal operation, and assembly work for the nine remaining modulators is in progress. In the tunnel, about half of the linac has been installed. The cooling system is completed along with the precision temperature controllers. The installation work will be completed by the end of 1993. We present the updated construction progress of the PLS 2-GeV linac.<
