How long does it take to prepare an accelerator prior to it being
used for experiments?
Since accelerators utilize charge particles, the typical time to prepare
the accelerator is the time required to bring the machine down to
vacuum, depending on the accelerator and the volume this might require a
day or two. Vacuums in an accelerator range from ten to the minus six to
ten to the minus eight torr.
