1. NIU Trigger Workshop CTT Commissioning Trigger Workshop October 22, 1999 WBS 1.1.5.3 & 1.4.3.3 Presented by Fred Borcherding for the D0 Electronics Group

2. NIU Trigger Workshop Fred B. - Oct 22, 1999 2 Charge for the Workshop For each of the NIU sessions, we would like to have some prepared talks to cover the following: 1. Schedule of completion of the hardware 2. Test program at the board level (who, where, when?) 3. Test/commissioning of the sub-detector trigger or framework prior to commissioning in the D0 environment in the D0 Hall. (who, where, when?) what other resources are needed (serial links, downloads, COOR, clocks, etc.) 4. Commissioning in D0. What is the sequence, time estimate for the commissioning? How will cosmic ray studies be used? What interactions with other systems are required? Give an estimated schedule for commissioning.

23. NIU Trigger Workshop Fred B. - Oct 22, 1999 23 ‘In Place’ Commissioning  Four Separate Systems can proceed independently  Each of the systems is commissioned in 3 Stages - u same as sub-system commissioning outlined earlier u Each stage adds more hardware u Each stage requires more software  A 4th stage - CR running - added with no special hardware  NOW Host software is ON-LINE  Can start with ‘one crate’  Can finish within one month after last crate u or about 3-4 months total time (whichever is longer)

24. NIU Trigger Workshop Fred B. - Oct 22, 1999 24 Overall Software Needs  KISS Applies u keep it simple  Have different types of users u technicians u engineers u physicists  Have different environments u Stand alone bench tests u sub-dectector u as part of full detector u possible CR running  Have different goals u test/fix/maintain individual boards u develop system expertise u test/fix/maintain full system

25. NIU Trigger Workshop Fred B. - Oct 22, 1999 25 Software cont.  Bench Tests u traditionally used PC, bit3 and windows /excel based software u need users (technicians & engineers) to be able to understand and modify software  Full system tests u want to run within full D0 system u run Examine’s and Calib’s with ON-LINE  Partial systems u gray area between bench and full system u in use / development at lab 3

26. NIU Trigger Workshop Fred B. - Oct 22, 1999 26 Infrastructure Required  Bench Tests u PC u Trigger / clock generator u Input generator u Output capture u Group will provide s software / firmware s test fixtures s procedures u Need - s Physicists for system design / data analysis s PC based software help

27. NIU Trigger Workshop Fred B. - Oct 22, 1999 27 Infrastructure Required * Need new bodies for these outside of present group  Full system tests u trigger generation u SCL (clock and control) u DAQ u Online u Group will provide s special trigger generator hardware s test fixtures u D0 provides s online system and software s examine and calib shells u Need* s MC Track generation software s MC Cluster generation software s (for CR) found-tracks to survey to new trigger-equations s Examine & calib software s help with special firmware

28. NIU Trigger Workshop Fred B. - Oct 22, 1999 28 Summary  Hardware will arrive relatively late  Much work between production of hardware and running  A lot of support and fixture hardware needs to be designed and built - Schedules will suffer without needed EE support.  A lot of support software needs to be written, and shaken out - Schedules will suffer without needed PH support.
