Summary notes on the BLS-to-ADF Transition System and General Installation which may be of use to the SCIPC. Sidewalk Test Stand The racks, power and safety have been in place since mid-March. http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/Installation/Drawings/SideWalkLayout.pdf Linda Bagby is editing the pORC document to permit 24/7 unattended power operation of all crates at the sidewalk test stand. Without this approved document, we have been obligated to power down the crates at the end of each day's activities. This document should get higher priority so: a) power cycling is minimized and b) less time is spent bringing up the various systems. Dan Edmunds and Hal Evans are writing and/or gathering the information on the ADF and TAB/GAB systems to be incorporated into the pORC. The power from the sidewalk outlets to the power supplies is already documented. http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/Sidewalk/PowerandInterlockWiring.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/Sidewalk/ACdistributionBox.pdf The L1 CAL Upgrade Integration Group strongly supports keeping the Sidewalk Test Stand functional for the long term. This proposal was offered a month ago: http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/Installation/Notes/2005-04-08_installation.txt The crates in current use at the Sidewalk Test Stand will go into the MCH1 during the installation this fall. We would then use a/the spare crate for future test stand efforts. If MSU and Columbia plan to maintain separate test stands at their respective institutions, we need to make sure we have enough spare crates: ADF, TAB/GAB and Communication. We also need to look into other components, for example, SBC, SCLD, VME/SCL, etc. Installation A year ago, the plan was to build the racks on the test stand and roll them. This has been scrapped. Instead, the racks currently in MCH1 will be reused. A team of physicists will carefully disconnect the existing BLS trigger cables and hide them in cable guides on the front of the racks. Then, a crew from the electrical and mechanical operations will tear out the old crates, power supplies and surplus cables down to the bare frames. The SCIPC report is out of date on this respect. It may be necessary to install new water lines. The power distribution in MCH1 will need no modifications - we already have the AC distribution (Pulizzi) boxes for the Run IIb system that make use of the current phase power. A pending D0 Note (4651) will describe how the BLS trigger cables will be disconnected, redressed and rerouted for the upgrade. Another pending D0 Note (4768) will describe the labelling scheme of all cabling in the upgrade. The note will give every label name (origin and destination). Also, the mechanical schematics of each rack, crate and board will be included to provide an unambigious reference. Files pertaining to the draft document can be found here: http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/labels/ The inter-rack wiring diagram will follow from the cabling labelling. BLS-to-ADF Transition System Two issues. 1) The method of reusing the existing BLS trigger cables was given almost no consideration in the TDR. 2) The ADF and TAB/GAB systems were built and tested largely independently, so some cabling features were overlooked The transition has two parts: a) Input to ADF and b) Output of ADF. The latter was not considered until three months ago during the ADF-2 Card Review at MSU. Part a) is nearly done. The signal integrity and impedance matching was checked and cross-checked, and reported in D0 Note 4692. http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/D0Notes/D0Note4692.pdf The full production of pleated foil cables (160 + 20% spares) were ordered, and the first 10 arrived from Sub-Sem for our approval. We need a test card which will simplify testing of all the Transition System components. A design for the test card is still pending, but we plan on working on it this week. Meanwhile, we will try to devise a method of checking out the 10 pleated foil cables, so we can approve the production of the remaining 182. We will need 40 Patch Panels, four in each of the 10 L1 CAL racks. http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/pdf/L1CalTrigPatchPanels.pdf The Patch Panel schematic is complete, and we are currently seeking a company to make them. http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/Sidewalk/434198.pdf The Patch Panel Card schematic is also done. http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/patchpanel_revb_20050422/L1Caltrig_patch%20panel%20card%20rev%20b%20Assy.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/patchpanel_revb_20050422/PATCH%20PANEL%20CARD%20REV%20B.pdf A requisition was submitted for 25 Patch Panel Cards, to be built by Pentaplex. For full production, we will need 80 Patch Panel Cards + 20% spares A new component which has been developed in the past couple of months is called the ADF Transition Card (ATC). We have completed a couple of reviews, tested a mechanical mock-up, and worked hard to get the channel link correct. A major hurdle was correcting for the rotation of the LVDS connector with respect to the ADF backplane output and the TAB backplane input. John Fogelsong, John Anderson, Johnny Green, Linda Bagby and Dan Edmunds have put in a lot of effort on this. http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/adf_transition_bd_20050509/adf_tab_connectivity_Model_1.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/adf_transition_bd_20050509/FlippedConnectors10May05.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/adf_transition_bd_20050509/L1cal_adf_transmod4_board_outline.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/adf_transition_bd_20050509/adf_transition_bd_20050513.pdf http://www-ppd.fnal.gov/EEDOffice-w/Projects/dzero/L1_Cal_Trig_Patch_Panel/WorkingDocs/adf_transition_bd_20050509/L1cal_adf_transmod4_FPSS.pdf In the past week, Johnny Green has filled out several requisitions for all the parts and pieces needed for all 80 ATCs + 20% spares. We will order 25 prototypes ATCs, so we have enough to populate an entire ADF crate backplane, as well as a few to send to MSU for additional testing. We should have the ATC prototypes in hand within the next 30 days. A pending D0 Note (4130) will describe the full BLS-to-ADF Transition system. The latest bill of material costs for the Transition System was updated by Johnny Green on May 13th. http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/Installation/Purchases/2005-05-13_L1cal_trig_fanout.pdf The schedule and costs have been updated and incorporated into the Microsoft Project by Darien Wood (May 18th). http://www-clued0.fnal.gov/~alstone/D0Work/L1Cal/Installation/Purchases/bls_trans_system_v3.pdf Alan [18 May 2005]
