V8.6.2 reserved for active veto tests V8.6.3 --- Changes as of run 76635 - 30 March 1994 (ASB) Prescales added to JET_GAP_HDE V86-06E30.PRESCALES 10 V86-04E30.PRESCALES 5 V86-03E30.PRESCALES 2 This is a temporary patch to avoid problems with the preferential selection of multiple interaction events which causes large events which causes muon FEB rates of 25% at 5e30. V8.6.4 --- Changes as of run 77151 - 7 April 1994 (ASB) First run on 4/10 16:26, first run after 4/5 power outage. Activated the MI_BEAM condition for JET_GAP_HDE and JET_GAP. The B-physics group currently does not wish to use the MI_BEAM condition so I switched the triggers MU_1_LO_JET, MU_2_LO_JET, MU_2_LOW to use good_beam. mi_beam is defined as per Jeff Bantly: define mi_beam { good_beam & l0_mi_flag_0 & l0_slow_inter & l0_slow_z_good }; removed the prescales from JET_GAP_HDE v8.6.5 Changes as of run 77352 14 April 1994 (ASB) made a mistake in the prescale list for v86_04e30.prescales and had made JET_GAP_HDE prescale 2 in v8.6.4. v8.6.6 Changes as of run 77436 15 April 1994 (ASB) Run co-ordinator requested that cd hitfinding be turned on. While doing that, the level 2 monitor stream was also activated. The hitfinding failed, but the monitor stream worked. Changed by hand LUM_MON-v86.trig to add stream monitor, ran mark and pass only on MU_1_MAX at a rate of pass 1 of 10000. The hitfinding failed due to a problem with the l2 exe. These changes do not effect physics data v8.6.6a With instructions from me, the DAQ expert Cathy Cretsinger preformed a second test of the cd hitfinding after the level 2 exe was updated. The test was run 77478, and after the test data is verified, cd hitfinding will be turned on. v8.6.7 Changes as of run 77512, 18 April 1994 (ASB) Trigger tower -5,26 (large tile -1 4) turned off in *.rs files.

This trigger is now prescaled at higher luminosities. 3) Replaced MU_1_JET_MON with MU_1_LOW, which requires MU(1,y4) MX(1,y4,lo) at Level 1 & Level 1.5 and MU(1,3,best) at Level 2. Also changed prescales for this trigger. 4) Added monitor filter to JET_MIN, EMJET_7 = L2PS(100)JT(1,7,0.3,EMF>0.8) 5) Moved GIS_DIJET to EM_1_MAX. Added jet seed to EM_1_MAX.

Level 1 Large Tile Et threshold reduced from 60 to 35. In addition, 2 seed tiles are new required instead of the previous one. Now Level 1 = LJ(1,25)LJ(2,6). 8) Bit 26, LJT_MAX is modified in same manner as Bit 25. Now Level 1 = LJ(1,25)LJ(2,6). 9) W->jj filter added. EM2_WJJ hangs from EM_2_MED.

All L2 muons require an L1 seed except for the 2nd muon for filters DIMU_LO_JET, MU_2_HIGH & DIMU_JET_HIGH. V10.0 - Released 31 October 1994 - Start Run 85277 Numerous changes. Many triggers/filters were either changed, renumbered, reordered, deleted, or merged. Refer to trigger list for details. V10.0.1 - Released 2-Nov-1994 - Start Run 85328 Reduce eta coverage of mu_2_low from y3 to y2. V10.0.2 - Released 8-Nov-1994 - Start Run 85594 1) Add L2_COMFIRM_L15 to all filters hanging off EM_1_HIGH & EM_2_MED. 2) Change L2 prescale on SCALAR_ET_HT from 5 to 1000. V10.0.3 - Released 13-Nov-1994 - Start Run 85780 Remove L2_COMFIRM_L15 from all filters hanging off EM_1_HIGH & EM_2_MED. V10.1 - Released 28 Novenber 1994 - Start Run 86279 1. Prescales: All L1 prescale files are identical to trigger version 10.0 except L1 prescale has been changed from a. 1000000 to 1 @ 8E30 and 1000000 to 2 @ 11E30 on JET_FAR_SUP trigger. Such a large prescale at these luminosities on JET_FAR_SUP in trigger version 10.0 was due to a misunderstanding. b. 2 to 1 @ 11E30 on MU_2_LOW. 2 to 3 @ 11E30 on MU_1_HIGH. This will reduce approx 14 Hz from W->mu trigger and add approx 19 Hz to Z->mumu trigger. Overall change 5 Hz. We hope to live with it. c. 500 to 200 @ 11E30 on MU_1_LOW. Will change rate by 0.6 Hz. 1000 to 200 @ 15E30 on MU_1_LOW. Will change rate by 0.8 Hz. d. 10 to 20 @ 20E30 on MU_1_LO_JET, will reduce rate by 4 Hz. e. l2prescale on MU_1_LO_JET changed from (1,2,4) to (1,4,8). 2. MU_1_HIGH: (EW GROUP) Added scintillator at level 2 with all the filters. Thus filters MU_1_MAX, MU_1_HIGH and MU_1_MON now has COS_REJ instead of MUTAG_ONLY. MU_2_MAX has L2_SCINT instead of NOCOS. Made mu15 (1, y2, high) to mu15 (1, y3, high) to make things compatible. For version V10.0 it was mu15 (1, y2, high). It seems to work but Leigh will give me a definitive answer after talking to Ken Jones. 3. EM1_EISTRK_MS: (GM STREAM) Filter em1_eistrk_ms will now go to GM stream. In version 10.0 this was not happening due to a small bug in the trigparse. 4. GIS_DIGET: (NEW GROUP) Photon eta has been changed from 2.5 to 2.0. Also added is the requirement L2 HT > 70 GeV. 5. GIS_DIJET_QCD: (QCD GROUP) Added another filter for the QCD group with l2prescale(1,5,10) & EM(1, 15, gis,<1.0) JT(3, 15,<3.0) 6. ELE_JET_1: (NEW GROUP) added isolation and tracking to electrons. 7. MU_JET_HIGH: (TOP GROUP) Added MU15(1, Y3, LOW). Added l2_confirm_l15 (1, y2, high) to all the filters hanging from MU_JET_HIGH. 8. MU_JET_HIGH: (TOP GROUP) Added l2prescale(1,1,5). 9. MU_JET_MAX: (TOP GROUP) Added calorimeter confirmation and changed the name to MU_JET_MAX_CAL. 10. Moved JET_3_MU from JET_3_MISS to JET_MULTI. Cone size changed to 0.5. 11. JET_3_MISS: (NEW GROUP) Since JET_3_MU has been moved from this trigger, the jet seed JT(1,3) has been removed from this trigger to save some time. 12. Added L2_CONFIRM_L15 to all the filters of EM_1_HIGH and EM_2_MED trigger. V10.1.1 - Released 2 Dec 1994 - Start Run 86490 1. Changed from L2_CONFIRM_L15 (1,Y3,LOW) to L2_CONFIRM_L15 (1,Y2,LOW) on trigger bit 3 MU_2_LOW. V10.1.2 - Released 7 Dec 1994 - Start Run 86693 1. Gate width on muon scintillators changed from 100 ns to 50 ns. 2. L1 prescale changed on two triggers as shown below. 4E30 6E30 8E30 11E30 MU_2_LOW_Y4 from 2 to 1 from 3 to 1 from 4 to 2 from 15 to 8 JET_MIN from 100 to 200 from 250 to 500 from 1K to 2K from 2K to 4K V10.2 - Released 09 Jan 1995 - Start Run 87804 The major changes from V10.1 version are: 1. Defined define mu_track_y1 {track_in_road='L10_(y1)'}; define mu_all_y1 {track_in_road='all_(y1)'}; for use in central muon triggers MU_2_CENT, MU_1_CENT and MU_1_CENT_MAX only. 2. Changed the L15 term for cal confirmation to include LE_Param_3 which is the EMF cut on EM cluster. 3. New trigger bit MU_2_CENT included. 4. New trigger bit MU_1_CENT included. 5. New trigger bit MU_JET_CENT included. 6. Trigger bit JET_MIN removed. 7. Introduced EMf = 0.85 requirement at L1.5 for EM_1_HIGH and EM_2_MED trigger. 8. For EM_2_MED trigger trigger changed the L1.5 threshold from 10 GeV to 12 GeV. 9. Now MU_2_CENT instead of MU_2_LOW will go to gm_stream. 10.Filter bit MU_ELE does not go to express stream. Filter bit MU_ELE_BEST now goes both to gm and express stream. 11.Filter MU_JET_MAX_CAL hanging from trigger MU_JET_HIGH has been replaced by the filter MU2_JET_HIGH. 12.MU_1_LO_JET : L2prescale(1,4,8) raised to L2prescale(1,20,100). Comment : Once 4th L2 prescale set is available we should be able to lower the L1 prescale on this trigger. 13.EM1_ELE_MS_MON : Applied L2prescale(1,4,10). Comment : We are really over budget at L2 for high luminosity settings. Without these L2 prescales this filter was taking 0.56 and 0.90 Hz respectively at 15E30 and 20E30 prescale sets. 14.EM2_WJJ : Raised L2prescale(1,5,300) to L2prescale(1,100,500). 15.JET_3_MU : Applied l2prescale(1,1,10). Comment : Expect to remove L2 prescale as soon as filter improvements are made. V10.2.1 - Released 23 Jan 1995 - Start Run 88180. 1. Trigger bit 4 MU_2_CENT does not go to GM stream at all. 2.
