Capability vs Cost for Servicing and Handling System Choices in 200-BeV Accelerator Design Study

Unprecedented size, residual radiation, and the need for quite reliable operation of the 200-GeV accelerator present new challenges in servicing and maintenance. Yet costs must not be disproportionately large. An example servicing solution is developed, and variations are investigated for costs. It is shown that large-percentage cost changes are not to be expected, but that small changes can represent millions of dollars. Therefore extraordinary care should be exercised in refining appropriate solutions. The era of thorough preconstruction mock-up work has arrived in the accelerator business!
