Extraction point and transfer measurements
and vetos
You what?
Quality issues
• For extraction system, have been told (EW)
• That k (1 /n) = x/ < 0.5
• Contributions are– Bumpers 0.059
– MKE 0.254
– MSE 0.259
– Orbit 0.2mm? 0.24 (already large)
Linear sum 0.812, Quadratic sum 0.44 (but not random)
Extraction system equipment protection
• BPCE interlock on bump: – veto if orbit > +/-1 mm
• Power supply interlocks– Bumper, MSE, MBHC, MBHA
• MKE interlocks– Charging voltage– Erratic / missing detection – fires clipper switch
What we don’t have…
• Beam intensity interlock– Needed already in 2003 – equipment safety & RP
• Beam energy?
• Beam size… – (what if CNGS beam extracted to TI 8…?)
