Performance and calibration studies for run 415 (momentum scan @ 25 degree).
- CERN 18
- S415, bar with 3-layer spherical lens
- p/pi @ 25 degree polar angle
- geometrical reconstruction
- delta t selection with s = 0.5 ns
- with beam direction correction
- with per-PMT Cherenkov angle correction
Performance for the run 415:
Geomentrical reconstruction:
Time imaging:
Per-angle plots:
Steps scan of the lens. Separation power of the time imaging as a function of lens's steps:
Rotation scan of the prototype. Separation power of the time imaging as a function of prototype rotation relative to initial one:
