Extraction devices Specifications

• Measured beam emittance for high intensity
  protons, made in 1996
• eh99,N 98 p mm-mrad
• ev99,N 85 p mm-mrad
• To make the acceptance of H20 and F10 gt99 p
  mm-mrad for 8 GeV high intensity protons, then we
  require the following apertures
• F5
  F10 H20 (mm)
• horz. gap (mm) 44.45 38.1
  10 - 30 (variable gap)
• vert. gap (mm) 25.4 30.4
  30.4
• Length (m) 0.667
  0.811.222.03 2.3
• Septum (mm) 0.76 13.5/15.85
  0.051
• Bend (mrad) 1.1 18.5
  0.43
• Field 2.1 kG (40) 14.4 kG
  80 kV/cm
• (currently F10 and H20 gaps are 20 mm)

Mechanical Group Schedule Outline

• FY 2005
• cost estimates and preliminary design work
  depending on the complexity of the projects (110
  to 220 hours ).
• FY 2006(buy parts for those things that we know
  the design for)
• AGS magnet coils sextupole and quadrupole
• Booster magnet coils
• uncoated AGS vacuum flanges
• the Booster F6 spare magnet
• new RC networks
• new F10 magnets (if the design is not radically
  different ).
• Summer of 2006
• rework as many AGS dipole and sextupole magnets
  as parts will allow.
• If possible the new F10 magnet should be
  installed.
• FY 2006 (start the design and testing effort )
• new electrostatic septum
• new AGS RC networks
• the F5 magnet
• the Booster injection dumps.

5
Mechanical Group Schedule Outline

• FY 2007 (purchase parts)
• the new F5 magnet
• the Booster C5/C7 injection dumps
• if possible the new electrostatic septum. The
  design of the new electrostatic septum should be
  completed during the year and parts should be
  purchased.
• Summer of 2007
• assemble install the new F5 magnet
• prepare the AGS ring for the installation of the
  new electrostatic septum.
• Rework any remaining AGS or Booster magnets.
• If new absorber or diffuser assemblies are to be
  installed in the AGS or Booster rings it should
  be done in FY 2007.
• FY 2008
• the new electrostatic septums should be
  assembled and tested and then installed during
  the summer 2008 shutdown.

ICFA mini-workshop on septa

• Tentatively scheduled to take place here at BNL
  during the first week of March, 2005.
• Will include experts from J-PARC, KEK, GSI, CERN,
  FNAL

7
CFI Issues

• 25 MHz RF Cavity shielding and access.
• What is radiation dose when cavity is on ?
• RHIC Cavity measurements
• 2.5 rad/hr at 9 ft.
• scaling to 1 ft, 13-99 rad/hr
• Do we need to run the cavity when the AGS is open
  ? How much time will the cavity require to be
  conditioned ?
