RSVP Beam Development Plan (BDP)

• 2Dec04 Thursday meeting
• ahrens

2
Summary of todays update

• November 04 Plan The Old Plan
• Boundary conditions
• Beam time requirements
• Weaknesses and strengths
• The Next Iteration Present Thinking
• Changes in boundary conditions
• Resulting dependencies -gt redo to come

3
BDP.4 (the old plan)

• 4 years of beam development
• Extraction work planned every year
• Intensity work (low duty cycle) planned every
  year
• All final hardware available by third year

4
BDP.4 (old plan) Beam Time Estimates

• First two years 10 calendar weeks/year
• Last two years 30 calendar weeks/year
• Some numbers details
• 80 hr/week i.e. behind RHIC
• 1 hr an hour of working time, 24/7
• Final estimate included Meco and Kopio estimates
  for beam line / experiment setup time
• which accounts for half of time for the last two
  years

5
BDP.4 Weaknesses too expensive, but also

• Early intensity development activation of areas
  to be reworked shortly
• AGS extraction
• low duty cycle approach required but not a
  proven way to deliver improved intensity setup
• Activation issues will over-constrain behavior
• Staffing
• Early years 24/7 not likely, no other user
• Early years - RHIC activities will compete too
  well

6
BDP.4 Strengths

• Progress possible early on on time structure
  issues using very low intensity
• MECO 7.5 GeV/c extraction and mini bunching non
  closed issues
• KOPIO maybe know enough (?)
• Progress possible on a subset of intensity issues
• Booster injection losses

7
The Next Iteration Revisiting the Plan

• Drop first two years, but plan for three years of
  development/commissioning
• High intensity extraction equipment available
  year one
• High intensity diagnostic equipment will be more
  available
• Booster loss monitors ...

8
Revisiting the Plan (cont.)

• Coarse time evolution of BDP is unchanged
• For intensity work, beam dumping assumed via 8
  GeV extraction
• MECO extraction issues ready for attack
• KOPIO issues when 25 MHz cavity is available
• Mix of possible activities make 24/7 more
  plausible
• Provided the corresponding mix of people is
  available
• Activities? No surprises Intensity, MECO
  extraction, KOPIO extraction

9
Dependencies - intensity

• Low intensity work (2e11)
• Nothing
• Modest intensity work (1e12)
• AGS extraction equipment upgrade
• External beam dump
• Booster loss monitor system rebuild
• Booster C3 protection
• Caps

10
Dependencies intensity

• High intensity 10e12 protons
• Booster injection area rework C5,C6,C7
• RHIC required magnets upgraded or spares ready
  F6 septum, F3, A5 kickers

11
Dependencies MECO

• Meco Extraction
• Time-structure-instrumented beam line
• Modest intensity
• New 8 GeV extraction gear
• Beam dump

12
Dependencies KOPIO

• Kopio extraction
• 25MHz cavity
• 24GeV extraction line
• Time-structure-instrumented beam line
• For modest intensity dump
