All
are moveable, and the Copper collimators are located in areas (period 6&7)
where radiation is less of
an issue. Once their operation has
been established, these areas will be heavily shielded.
It
is hoped that this collimation could reduce important losses by up to a factor
of two – possibly more in
critical areas.
Status: All collimators are in and have been
exercised. Initial results look
encouraging. A preliminary shielding design is complete
and shielding should be installed over the next few months.
