Chapter Eight - Radiation
Safety
Keys:
There are essentially two types of interlocks and
associated keys: white and other. A "white key" interlock is
an interlock that leads directly to the CESR tunnel or to an area
that cannot be entered when the beam is on. At no time while
the linac or CESR is running can you enter a white interlock without
tripping an interlock and dumping the beam.
Other interlocks, located in CHESS West and CHESS
East can be set in "bypass" mode with a color-coded key that allows
users and personnel to pass through interlocks to the experimental
floor and work stations even when CESR is on. The CHESS West
interlock requires a yellow key be in place to set it in bypass
mode. The CHESS East interlock requires a blue key. The
yellow or blue key cannot be removed while the synchrotron is on -
if you do so, the interlock will become activated and if anyone
passes through it, CESR will be shut down.
To find out more about the color-coded keys and
the areas they allow access to, speak with the Operations Manager or
an experienced CHESS Operator.
