Radiation levels in SSC (Superconducting Super Collider) calorimetry
Estimates of ionizing dose and neutron fluence have been made for typical SSC detector configurations exposed to radiation from p-p collisions. Using a description of average events'' in conjunction with simulations of secondary processes, it is found that in most cases the ionizing dose (D) or neutron fluence ({phi}) can adequately be expressed as D (or {phi}) = (A/)(r{sup 2}sin {sup {alpha}+2} {theta}). Here A depends on the process and exposure time, and {alpha} is slightly less than unity. For calorimetry r is the distance from the interaction point. Under nominal conditions a calorimeter element 2 m from interaction point and 6{degree} from the beam line is subjected to an annual dose is 0.1 MGy at electromagnetic shower maximum and an annual neutron fluence of 10{sup 14} cm{sup {minus}2} at hadronic cascade maximum. A detector at an 8 TeV {times} TeV p-p collider with the same physics reach'' would experience about 27 times as much radiation. 21 refs., 7 figs., 2 tabs.
