Subject: Closeout of L1 CAL TRR From: Bob Hirosky Date: Sat, 27 Aug 2005 14:30:10 -0400 (EDT) To: "Vivian O'Dell" CC: Bob Hirosky , Dean Schamberger , Marco Verzocchi , , Bob DeMaat , Norm Buchanan , Darien Wood , "'Brian Padley'" , Hal Evans , Maris Abolins , chipbrock , "Gerald C. Blazey" , The committee feels that the L1CAL system is well on track to begin installation on Oct. 31. The remaining tasks to complete the system are well understood by the L1CAL group. In this preliminary report we note the following tasks that should be pursued with high priority to complete the remaining checks of the system and to prepare for installation. While a few additional recommendations are also included in this draft, the complete list will follow in the full report from the review. We also commend all of the speakers on their very well prepared presentations. Bob Hirosky for Bob DeMaat, Dean Schamberger, Marco Verzocchi, Norm Buchanan, and Taka Yasuda Comments/recommendations from the Closeout session -------------------------------------------------- Out of time events: The presence of out-of-time (zero energy) events in the TT readout at the few 10ths of a percent level need to be understood. This should be pursued immediately and at highest priority. L1CAL should be running in the trigger system as soon as the GAB is timed into the TAB and made to communicate w/ the framework. Operation of the system w/ at least 40 ADFs and all TABs prior shutdown must be demonstrated. Acceptable BERs should be demonstrated over multiple days of running. We recommend the creation of a detailed installation schedule by Oct 1. We urge the group to build in additional contingency for the installation and testing phase, possibly by finding efficiencies in the disassembly phase. A large amount of software needs to be completed to verify and operate the L1 CAL trigger. We recommend the generation of a software task schedule for on-line trigger control, slow control, monitoring (TCC monitoring and Examines), and alarm system software with manpower required to reach completion by Dec 1. Critical components required earlier for the installation tasks should be clearly defined. The L1CAL group and the trigger management/D0 Spokesmen should work to ensure timely ORC approval for the test stand within the next week. We recommend completion of the jet firmware verification by the end of Sept. This should be completed to the same level as the verification of the electron algorithm. The protocol for communication with COOR should be fully defined within the next week. The documentation project for non-expert shifters should begin well in advance of turn-on. We recommend that L1CAL start providing weekly reports at the operations meeting. MOU agreements for long-term maintenance should be formally negotiated w/ the D0 Spokes. New manpower should be added to provide an updated calibration of the present L1 TTs and to repeat this work for the new trigger after the upgrade. The group should also consider finding new manpower to develop monitoring tools via TCC, possibly including a hot tower finding tool TCC. This work should proceed in addition to other L1CAL tasks and not detract from efforts by Dan and Philippe on installation and commissioning of the system. -- ...............................................................
