  1. VSVX Efficiency for special runs Yurii Maravin FNAL

  2. Data Samples • Use offline data, reconstructed with p13.06.00 • Run 169716 (nominal charge integration window) • Run 169717 (132 ns delay) • Runs 169718 and 169721 (264 ns delay) • Run 169719 (132 ns early) • Run 169720 (264 ns early) • Apply the same code used to estimate VSVX efficiency • Calculate VSVX efficiency using this formula:

  3. VSVX Efficiency as a function of f 132 ns late nominal 264 ns late 132/264 ns early

  4. VSVX Efficiency as a function of h 132 ns late nominal 264 ns late 132/264 ns early

  5. VSVX Efficiency as a function of pT 132 ns late nominal 264 ns late 132/264 ns early

  6. Summary • VSVX efficiency (with respect to SVX hit efficiency) as a function of the integration window: • Some recent runs were taken last Friday – data files are being analyzed, and results will be ready soon.
