FACET Laser TransportCost and Schedule Estimate R. Bergan 8/2012
Laser Transport Overview • The start point is in the FACET laser room (still needs modification). • The end point is directly below penetration 20-11. • The design will be based on the LCLS injector laser transport. • The laser must be fully enclosed at all locations – except during alignment, when safety precautions will need to be followed.
Rough Dimensions • These dimensions were gathered by tape measure inside and outside buildings without good references – therefore they are accurate to within +/-6 inches. • The metrology group can provide more accurate numbers sometime in October. • The end point in the tunnel is 60 inches below the ceiling (also 60 inches above the floor) • The floor heights in the laser room and klystron gallery are assumed to be even.
Vacuum Pump • The recommended vacuum pump is Agilent (Varian) TPS-Compact TV 301 Conflat 6 inch • 9698222 : 120 V $11,966.20 • 9698230 : 240 V $11,966.20 • The lengths have been reviewed by the sales rep. and only one pump is required.
Major Layout Concerns • There is a large cement wall in the klystron gallery that should be avoided. • The height of the lowest point going across the Klystron gallery has to be greater than 9 feet. (height of status lights and cart doorways) • The large ion pump above the 20-11 penetration has to have forklift access for maintenance and/or repair.
Not covered in this estimate • Cost for MFD dropping the drift tube into the penetration. • Cost for MFD to complete the installation. • Cost for reconfiguring the laser room. • Cost for adding a hole from laser room to Klystron Gallery.
Penetration Support • The existing TCAV support will be used to hold the tube down the penetration.
