Access to Hall C will be governed as described in the ``JLab Beam
Containment
Policy and Implementation" document dated March 1994, with the modification
that controlled
access entrances and exits will be monitored directly by an ARM (assigned
radiation monitor)
provided through the JLab Accelerator Division or a JLab Radiation
Control (RadCon)
Group member, and not solely via a television camera. Work in designated
radiation areas will
be governed by the JLab RadCon Manual.
Access procedures during Research Operations depend on the number of
individuals who
will be entering the hall and the length of time they are expected to be there.
A controlled access is used when a few individuals require entry for a
short period of
time. If the hall must be open for an extended period and many people will
enter, then you
should use the restricted access procedure instead of the controlled access
procedure. Normally,
when requesting a controlled access, the hall will be in either the Beam
Permit or RF Permit
State - for example, if the beam has been on or it could be shortly.
If the hall is not already in the Controlled Access state when you
wish to access it, you
must request a change to that state from the Machine Control Center at
extension 7050 and
indicate that you intend to make a Controlled Access. The MCC will then
send an Assigned
Radiation Monitor to survey the hall. Before anyone enters the hall, the
ARM will carry out a
radiation survey and post radiation areas. Subsequent entry by individuals
during the same
Controlled Access period does not require an ARM survey.
