   Thomas Jefferson National Accelerator Facility (Jefferson Lab),
   formally known as CEBAF, is a $600M facility located in Newport
   News, Virginia, USA.  It is a recirculating linac machine that
   utilizes super-conducting technology.  The accelerator is presently
   capable of operating at energies up to 4GeV with upgrades to 5 and
   6 GeV in the near future.  The accelerator delivers up 200 uA CW
   beam current to three end stations which can receive beam and
   perform experiments simultaneously. 

   The Lab has approximately 500 employees with approximately 100 of
   them assigned to the Accelerator Division.  The Accelerator
   Division consists of MCC Operations, Software, Radiation Control,
   Safety Systems, Accelerator Electronics Support (AES), and
   Operability Groups.  The accelerator is staffed 24 hours a day seven
   days a week by the MCC Operations Group.  Shifts are run utilizing
   a 'seven days on, seven days off' rotation with personnel switching
   from owls to days to swings every other week.  Operators are
   assigned control room duty for 70% of their time and are given the
   additional time to work on projects designed to increase the
   efficiency of control room tasks.  These projects take the form of
   software or hardware development depending on the talents of the
   operator.  Control room staffing consists of one Crew Chief and two
   Operators (soon to be three) per shift.  The Crew Chief receives
   their shift instructions from the Program Deputy who is assigned
   the task of scheduling and executing program control for a two week
   period. 

   Maintenance is scheduled approximately every two weeks and is
   generally followed by a number of machine development shifts. 
   There is only one extended shutdown period per year (5-7 weeks)
   which is scheduled to follow the December Holiday season. 

   Operations is strongly committed to the use of documentation to
   perform the tasks required to commission, setup and maintain the
   accelerator.  The documentation has an on-line delivery system that
   is accessible from anywhere on site.
