ES&H Issues for Design and Operation of Linear Colliders
We consider optimization of the generalized
luminosity per unit cost of a linear collider J.E. Spencer (SLAC)
in the current ES&H era. Several specific examples,
running over the length of the LC, beginning at the source and ending at the dump suggest that both costs
(capital and operating) and the environmental issues can be improved in a mutually compatible way. Thus, a RoHS
by any other name such as WEES or OSHA need not present thorny problems requiring unexpected technology R&D
but rather a push to leverage the many recent advances that might otherwise be avoided. While not mainstream,
the physics is challenging and the true amortized cost may be seriously underestimated by ignoring such issues. As
example, the entire, interior surface of a laser driven RF gun involves interesting materials science where the space
requires continuous UHV to sustain stable and acceptable quantum efficiency as well as avoid RF breakdown damage
in an environment that is also subject to radiation damage that can reduce output from window damage. Rad hard
systems can be like bug-proof software. They don’t have to be overly slow, large or heavy and provide opportunities
to innovate and justify the cost of such systems.
