Trying to exploit rate capability

• Rate test on Wednesday 18-Sep-2002. Result
• Reinhard 500 / 250 / 50 Hz
• Dmitri 400 / 200 / 40 Hz
• Measures of good/bad
• SCLinits per hour
• Pauses per hour
• Average FEB
• Live fraction
• Rate to tape
• Trying to separate rate dependent from non-rate
  dependent components of these effects
• Sources of downtime
• Crate 22 (l2muf inputs) caused by L1 FE
• CFT downloads
• SMT high voltage
• Notes
• We are collecting these measures run by run,
  using results to adjust prescale files
• This method is not ideal because
• Factors out of our control
• No run is perfect
