## Extraction devices Specifications

- Measured beam emittance for high intensity protons, made in 1996:
- h99%,N = 98  mm-mrad
- v99%,N = 85  mm-mrad
- To make the acceptance of H20 and F10 >99 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              0.81+1.22=2.03     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)

## 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.

## 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.

- Mechanical Group Schedule Outline

## 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

## 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 ?
