Comparison of new and old design • Reduced shielding • Keep the thickness along injector line as 44” • 1’ steel/lead + 32” concrete concrete lead steel
These questions arose from Last week LCLS-II Physics Meeting • If LCLS-II electron beam power is reduced from 5 kW to 3 kW, how it will affect the radiation shielding for • the LCLS-II dump and • LCLS-II BTH wall • Does RP have the experimental data to support the LCLS dump shielding design?
Radiation shielding for LCLS-II Main Dump Q1) If LCLS-II electron beam power is reduced from 5 kW to 3 kW, how it will affect the radiation shielding for LCLS-II main dump? 2 A1) Soil Concrete shielding could be reduced by approximately 1 foot in the bottom, and lateral directions Iron FEE 5 1 4 Concrete 3
LCLS-II new BTH wall Q2) If LCLS-II electron beam power is reduced from 5 kW to 3 kW, how it will affect the radiation shielding for LCLS-II BTH wall ? A2)
