Phase III. Performance at high rate

• Perform luminosity scan
• Beam and detector conditions:

- Beam flux 2. - 5. x 10^7 photons/sec.

- Exclude CDC/FDC/TOF at high rate if detectors are not ready (calibrate baselines if needed)

(repeat tests when sub-detectors are ready)

• Study L1 rate for various trigger thresholds

- Trigger types: FCAL & BCAL (& ST), TAGH & ST, (FCAL, BCAL)

- Ajust trigger parameters (busy thresholds, TS trigger inhibit thresholds)

- Check performance of electronics modules at high rate

(reveal electronics problems and limiting factors: data transmission rate, etc.)

- Study L1 trigger rate limitations

• Take data for several thresholds at different luminosity (check efficiency)
