  7. LCLSDrive-Laser Commissioning 8-Hour Cycle (5 days/week, 8/1/06 to 12/1/06, 16 total weeks) DAY SHIFT (8:00-16:00) W. White, J. Castro, D. Dowell, S. Gilevich, H. Loos, S. Peng (as needed) Also available: P. Emma, P. Krejcik, C. Limborg, J. Schmerge, et al. SWING SHIFT (16:00-24:00) (none) OWL SHIFT (0:00-8:00) (none) (see W. White)

  8. LCLS Injector/BC1 Commissioning 24-Hour Cycle (7 days/week, 12/1/06 to 8/1/07, 32 total weeks) DAY SHIFT (8:00-16:00) 1 lead physicist, 1 physicist, 1 controls eng., 1 sys. engineer, 1 LCLS operator, 1 laser operator SWING SHIFT (16:00-24:00) 1 lead physicist, 1 physicist, 1 LCLS operator, 1 laser operator OWL SHIFT (0:00-8:00) 1 LCLS operator, 1 operator, 1 laser operator

  10. Man-Power Requirements (12/1/06 – 8/1/07) • 32 weeks total (12/1/06 to 8/1/07, minus 2 weeks) • 80% coverage (downtime) • 14 lead-physicist shifts/week • 14 physicist shifts/week • 7 controls eng. shifts/week • 7 sys. engineer shifts/week • 21 laser operator shifts/week • (28 operator shifts/week) • Average of 2.8 shifts/week for each lead physicist • Average of 2.0 shifts/week for each physicist • Average of 0.5 shifts/week for each controls eng. • Average of 0.8 shifts/week for each sys. engineer • Average of 4-5 shifts/week for each laser operator (32 weeks)(214 + 27 + 21)(80%)  1600 man-shifts = 12900 man-hours  6.5 man-years (+ 2.9 from op’s)

  11. LCLS Commissioning Parameters

  12. Issues • Controls will be mixed (SLC & epics) and capabilities may be limited initially • Most High-Level Applications (emittance, bunch length, feedback) must done through MATLAB as a temporary solution • Most LCLS physicists not yet experienced in SLAC control room with SLC controls • Help from operations group will be needed
