Extraction point and transfer measurements and vetos. You what?. Quality issues. For extraction system, have been told (EW) That D k ( b 1 bg / e n ) = D x/ s < 0.5 Contributions are Bumpers 0.059 MKE 0.254 MSE 0.259 Orbit 0.2mm? 0.24 (already large)

Extraction point and transfer measurements and vetos You what?
Quality issues • For extraction system, have been told (EW) • That Dk (b1bg /en) = Dx/s < 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…?)
