Radiation levels in RE38 during nominal LHC operation

Simulated radiation levels at the location of the electronic racks inside the RE38 alcove under nominal LHC running conditions are presented. The levels are expressed in terms of total dose [Gy], 1MeV equivalent neutrons fluence and the fluence of hadrons having energy in excess of 20 MeV. When the...

description Simulated radiation levels at the location of the electronic racks inside the RE38 alcove under nominal LHC running conditions are presented. The levels are expressed in terms of total dose [Gy], 1MeV equivalent neutrons fluence and the fluence of hadrons having energy in excess of 20 MeV. When the average loss rate around the ring is 1.65¥1011 m-1y-1 the annual dose inside an electronics rack in the alcove is 0.05 Gy [Si], the annual 1 MeV eq. neutron fluence is 5 x 108 per cm2 and the annual high energetic hadron fluence is 5 x 107 per cm2. A standard concrete shielding chicane identical to those used in all other alcoves inside the LHC tunnel would reduce the particle fluences with a factor 10.
