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…?)
