  1. Trigger Board Mini-Workshop Fermilab, 1 North April 10, 2003 Trigger Menu for Luminosity 60-80E30 http://wwwd0.fnal.gov/RunIIaOperations/TriggerBoard/d0_private/workshop_10apr03/tb_wk_page.html • Ground Rules • Target Luminosity 60E30 but also quote trigger rates at 80E30 • Design for DAQ rates L1/L2/L3 = 1200/600/50 Hz • Level-3 will be running p15, which has some new filter capabilities • Design your triggers for calorimeter eta coverage up to 3.2.  • Monitor triggers should be requested and justified in association with the proposed physics triggers • All trigger requests should be accompanied with efficiency vs rate plots extracted from data • Rate estimates of proposed triggers should take into account overlap effects from similar type triggers

  2. JT_95TT CJT(4,5) L2JET(1,30) L3JET(1,95) 40E30 L1=52 Hz L2= 39 Hz L3=0.22 Recent L2 change increased L2rej from 1.06 to 1.33 Expansion to ||<3.2 increased L1 from 44 to 52 Hz but did not increase rate to tape* 60E30 L2=59 Hz 80E30 L2=78 Hz CJT(3,5) L1=156 Hz, L2=? *In general L1 increased by 20%, but L3 by 0-10% for all QCD triggers, must understand

  3. JT_125TT CJT(4,7) L3JET(1,125) 40E30 L1=11Hz L2= 11 Hz L3=0.04 CJT(7) may disappear. Could change to CJT(3,5), would need L2JET to control L2 rate.

  4. QCD Special Run-Low ET Studied new minbias+L3 jet monitor triggers Note the minbias rate is 270x the CJT(5) rate, but the L3 rate is 7x the JT_8TT rate, so if we replaced the JT_8TT trigger of .15 Hz (.22 at L1/L2), we would add about 40x More L2 (9 Hz) to keep the same L3. CJT(2,3) L3JET(1,15) has ~same L1 rate as JT_8TT, but 4x lower L3 rate, so could get 4x stats with same or better turn-on

  5. QCD Special Run-Gap CJT(2,5) L3JET(1,25) GAPN 40E30 pre=2 L1=3 L2=3 L3=0.6 L3(35) gives x2.5 rejection ; L3(45) gives x5 rejection allows addition of CJT(2,3) L3JET(1,15) x9 higher L1 x4 higher L3 (than 25 trigger) 40E30 CJT(2,3) L3JET(1,15) Pre=12 L1/L2=5 L3=0.4 CJT(2,5) L3JET(1,45) Pre=1 L1/L2=6 L3=0.24 60E30 CJT(2,5) L3JET(1,45) Pre=1 L1/L2=9 L3=0.36

  6. Summary Need L2 studies on CJT(3,5) trigger for setting thresholds for JT_TT95 and JT_TT125 Need link to turn-on studies Change current gap triggers from 25 to 45, add low ET gap triggers FPD triggers still in future
