Presentation Transcript

  1. BTV screens All details in EDMS Functional Spec LHC-BTVD-ES-0001-00-10 Input from Claude, Thibault, Joerg, Miguel, Marcel, Gerard

  2. Screen locations (provisional) • BTVSE – 0.55 m upstream of the TCDS entrance; • BTVD – 25.835 m downstream of the MKBV exit; • BTVDD – 30 m upstream of the TDE block entrance.

  3. Function • BTVSE • Setting up extraction (MKD kick, orbit) at different energies • BTVD • Setting up extraction (MKD kick, MSD kick, orbit) • BTVDD • Setting up extraction (MKD kick, MSD kick, MKB kick, orbit) • Monitoring of dump trace (MKB kick)

  4. Performance

  5. Beam loading Nominal cases Dilution failure cases

  6. Constraints • Cameras limited to 400x300 pixels (for compatibility) • Affects resolution • BTVSE – 2.2 (2.4) pixels per s • BTVD – 1.2 (2.5) pixels per s • BTVDD – 0.8 (1.1) pixels per s

  7. Screen sizes - BTVSE 50 x 40 mm

  8. Screen sizes - BTVD Cut by chamber 100 x 60 mm

  9. Screen sizes - BTVDD 550 x 550 mm

  10. Diagnosing MKB failures- BTVDD
