Human resource and collaboration Integration : M. Yoshida RF-Gun :T. Natsui Cathode : D. Sato (Titech) Beamline : H. Kumano (Mitsubishi), M. Chiyokura, LINAC Accelerator group Laser : – Fiber laser : Z. Xian, Y. Moriai (P.A.lab) – Control : T. Natsui, N. Toyotomi (Mitsubishi) – Solid laser : R. Zhang / T. Natsui – LD and Yb:YAG : Hamamatsu Photonics – Crystal bonding / growth : Taira lab(IMS) Beam transport : LINAC comissioning group (LCG) Thermal gun : T. Osawa, LINAC Accelerator group And many advisors – U-Osaka / RIKEN / U-Tokyo / AIST
Technology transfer to Mitsubishi operators Nd laser system was built by Mitsubishi.
24 hour operation Complete the simplest laser system – Reduce MTBF items Redundant RF-Gun and laser system – Reduce failure rate Required human resource : 1 week = 21 shift – Staff : 1 shift / week x 4 staffs= 4 – Expert operator : 5 shift / week x 2 staffs= 10 Sum= 14 ? Must increase expert operators. – More 2 experts (total 4) will be required.
Considerable faults of RF-Gun Cavity discharge Cathode degradation Laser window damage MTTR = 7 days ?
Considerable faults of laser system Failure rate = Redundant laser system is required.
