New 1st Splitter being designed

New part after 600m of TT21

• No space for BSGV.220075 - SEM

BDF line requirements

• 6 new profile and position monitors in existing TT21 (in 4 different locations)
• 10 new profile and position monitors in new BDF line (in 5 different locations)
  • 10 measurements per spill - 0.1 Hz
• 1 Full 2D monitoring, screen-type
  • In new line before dilution magnets
• 1 beam current monitor
  • In new line before dilution magnets
• A target beam monitoring system
  • Can be in vacuum
  • Placed at suitable location after the dilution kickers where dilution pattern can be resolved wrt beam size
• Beam loss monitors, 9 in total
  • Needs to be interlocked with 10ms reaction time

To do by ABT:

• Specify explicitly where position is required & where beam profile is required
• Add beam size at each location in table of requirements
• Add expected vacuum level in the line
• Resolution required on 2D monitor & furthest location from target where this could be placed

To do by BI:

• Cost estimate ASAP (Rhodri)
  • Base on SEM, BTV, BSI, BLM
• Manpower estimate not required for the moment
• Write-up for BI contribution using OVERLEAF
