##  ``Physics Tables’’ for Commissioning Run -- TDWG

- TDWG collected information from detector groups during CDFWEEK
- How much zero-bias data do you need?
- Do you want any specially triggered datasets?
- Do you want an special runs?
-  Thanks to participating groups:
- Muons, Muon-trig, Calo, Calo-trig,COT, CLC, XFT, XTRP,FE elec.,SVX, Alignment,  L2 Trig, Trig supervisor, DAQ, L3, Trigsim, QCD, other ideas

## Typical Requests

- Not a huge amount of zero-bias requested
- Too sparse to calibrate/check detectors
- Preferred single towers, stubs, tracks to make sure there is some useful energy in event
- We have put together three tables based on requests
- Tables can also be used with little or no modifications for special running conditions                                (*e.g.* 36x1, no B field etc., high rate)
-    Young-Kee will summarize those requests in her talk.
-  Read out all Trigger diagnostic banks

## Table  1  --  zero bias only

- Summary
- 20--50 Hz zero-bias
- Possibly add a L3 stream based on CLC E*W coincidence
- We will probably soon get bored of this table because either:
- luminosity is too low (no interactions); need some minimal bias
- luminosity is too high; would prefer to select those events with more particle production
- Will be useful for checking CALO timing before going to table #2 (expect to be OK from cosmic run)

## Table 2 -- Minimal bias

- Summary
- L1:
- 5 Hz zero bias   --  stream  1
- 5 Hz minimum bias (CLC E*W coincidence) -- stream 2
- 1 GeV (HAD+EM) tower anywhere  (N.B. If single PMT spikes are a problem -- we will know soon -- then we will change this to two towers) -- stream 3
- Loose CMU, CMP, CMX IMU -- stream 4
- L2: tagging but auto-accept
- L3: auto-accept, but split into streams as above
- This table is fine at L~1029

## Table 3  -- More advanced

- Summary -- works through 1031   (Mariner Max)
- L1:
- 1 Hz zero bias    -- stream 1
- 1 Hz minimum bias (CLC E*W) --- stream 2
- X GeV (HAD+EM) CALO as previous    --- stream 3                                  (threshold determined by luminosity)
- Tight CMU-CMP, CMX, IMU  --- stream 4
- 8 GeV EM tower  --- stream 5
- _***** and the following using XTRP: ****_
- 4 GeV “electron” (4 GeV EM tower matched to 1.5 GeV XFT)
- muons with phi match to 1.5 GeV XFT track
- single track trigger        --- all above stream 6
- Trigger group will add to this table to test triggers:
- MET-25,SUMET-120,L2 cutting, L2 prescaling w/L1 full-bore...
- L2, L3 tag  as  in #2

## A “physics goal” from comm. run

- 1/16” well-known aluminum plate mounted on SVX4 -- Carter Hall
- Collect  *ee*  conversions with EM tower trigger
- Can calibrate the X0 of the COT inner wall  -- was a 30 MeV systematic on  Run-Ib W Mass
- (Also calo triggers (jets & photons) could be used by QCD/EWK groups to understand energy scales.)

## Summary

- Have three basic trigger tables ready.  Expect to use mostly #2 for start of commissioning run.
- Simple tables
- L2 will tag
- L3 will be used to stream datasets
- Thresholds and rates limits can be modified easily to suit conditions
- YKK will talk about special runs
- Should calibrate COT material if all goes well.
