Now we have the FULL GROUP, this is our 1st Trigger Rep meeting…

Reminder: Plan for Summer

Phase I: Get system in stable condition (with improvements) (June - early July) we are now at step II, final physics tables waiting for EOS tests

Phase II: Trigger Table Cleanup and Optimization (today’s focus)

Phase III: Integrate new triggers (August - Sept)

Phase I: Get system in stable condition

--> see Veronica’s talk for details

Step I: Improving L2 JETs. DONE L2 JETs: improved the “Junk Enhanced Trigger” ROF shoulder threshold at full scale Opened up single track trigger at luminosity below 40E30 (JET_CALIB) Take data for a few stores with no other change, L2 JETs cross section improved dramatically As a result: triggers with DPS at L2 released much earlier

Step II: Switch to new XTRP firmware (early July) ready soon Check track trigger rate changes due to adjacent linker veto Mt cut trigger as test trigger with prescale, map out performace CLC multiplicity trigger as test trigger with prescale, map out performance Added new Z to BBbar and MET + b-jet triggers Take data for a few stores with no other change, data for offline analysis

Will see how much improvements the new track firmware will bring soon

Phase II: Table cleaning and optimizing

What’s the goal? Removing useless or obsolete triggers Add a few mature fully tested triggers Open up more triggers earlier at lower luminosity Increase 20KHz threshold up to 25KHz To pave the road for CLCM trigger and Mt triggers and integrate other test triggers

This is the first step towards table unification The details next….

Table cleaning 1: L1_TEN_TRK2 drives L2_PS0_L1_TEN_TRK2

This is in both high and low lumi tables, doing nothing exceptusing extra L1 bandwidth (will have some overlap)

Should be at least with PS250: L1_TEN_TRK2_PS250

Running at 6KHzdoing nothing, while overall L1A is 14KHz

Table cleaning 2: L1_TWO_TRK10_DPHI20_DPS (CHAMP trigger)

This trigger is in both high and low lumi tables, very high L1 rate at high luminosity when DPS is released.

fully open this trigger with lumi enable at around ~60E30, without DPS.

running at 4KHz,mostly fake junk!wasting L1 bandwidth

Table cleaning 2 (cont): L1_TWO_TRK10_DPHI20_DPS (CHAMP trigger)

At low luminosity, it behaves ok at L2. Much cleaner/pure evts Remove the DPS at L1! fully open it below ~ 60E30 Will get more useful data, without DPS Everyone wins here

Running at~30Hz at L2,mostly rejected at L3! Wasting L2bandwidth…

Table cleaning 3 (already done): L1_TRK10_PS250 for JET_CALIB: move to

DIRAC path

This is in both high and low lumi tables, very low rate though.

Fully enable (no PS) this trigger at luminosity below 40E30, to get more data for JET_CALIB. (done already). Thanks Ken who worked closely with us.

Table cleaning 4: L1_MB_CLC_PS10K for MINIBIAS_1HZ

This trigger is rate limited at L2: L2_RL1.3Hz, RL1Hz reduce the rate at L1: PS100K Have L2 RL3Hz which feeds L3 multiplicity with cut at 20 (to increase its rate) Then L3 prescale by 3, 1Hz for Minibias dataset (keep this the same) Have another L2_RL1.3Hz drives L3 with reco dataset, which feeds YMON.

Table cleaning 5: L1_TOF_14_MIP_&_CLC_PS10K for MINIBIAS_1HZ

This trigger is currently rate limited at L2: L2_RL0.5Hz running at about the same rate as L1_MB_CLC_PS10K, doesn’t do much Remove this trigger, free up L1 bit with high prescale to be used to

control the L1_TWO_TRK2_PS200 (high rate).

Table cleaning 6: L1_TWO_TRK2_PS200

This backup trigger is only in low lumi table It drives L2_PS1K_L1_TWO_TRK2 and L2_TWO_TRK2_D100_PS20 Ideally, would like to replace L1_TWO_TRK2_PS200 with PS4K But only four L1 bits can be prescaled by more than 255 change the PS to 4000 instead, and PS20 away at L2, PS1K ->PS50

Table cleaning 7: “unused?” datasets

Anyone else use these datasets? PLUG_DIJET

JET_20_CENTRAL

All DIJET_MASS (TWO_JET_xx_Mxxx)

So far, no one claimed any of the datasets.

Will remove them.

backup trigger for L1_MET15 (do we still need above backup?) prescale at L1 by 250 (cannot prescale by 1000) rate limited to 0.5 (?) Hz at L2. L3 auto-accept

Remove old Z to BBbar trigger (if new trigger data is ok)

Change COT spike bit to bit 63.

Anything else which is FULLY ready ?

We already have 15 items on this to-do-list! Try not change too many at one time!

Phase III: Integrate new triggers

August to Sept:

Finish integrating all mature fully tested triggers If you have triggers which are fully ready, they will be integrated! If you have triggers need more tests, let’s test them soon All new/test trigger requests should be done by Trigger Reps.from now on Trigger Reps: please finalize your list/plan at next two meetings Will have trigger rep meeting starting next week (Wed 2-3pm?) The meeting will be dedicated for integrating new triggers

Expand L2 bits from 128 to 192 (“Non-beam test successful” two days ago) Daniel will give a status report soon Take full advantage of new EVB upgrade, Pulsar Phase II L2 system and SVT upgrade (partially installed by then) We should be able to handle 150E30 luminosity with all the improvements The table should be stable by then for this luminosity range
