  1. How to power up the TRD updated David Emschermann Physikalisches Institut Universität Heidelberg

  2. Outline • Status and plans for the year 2007 • Global Tracking Unit (GTU) power • Power Control Unit (PCU) power • Power-up sequence of TRD • LV installation status at CERN • Summary

  3. Status at Point 2 • TRD SM in sector 08 fully inserted

  4. Installation priority Prepare services for first 4 SM by end of 2007 : 2007 08 00 • sector 00 • sector 08 • sector 09 • sector 17 09 17

  5. Global Tracking Unit 9 crates in total, externally powered by Wiener LV PS • for all GTU crates : • 1 interface to CTP • per crate : • 2 LV inputs • 2 SM partitions • for each SM : • 5 TMUs, 1 SMU • 60 ORIs from SM • 1 DDL uplink • 1 DCS board • 1 Ethernet uplink GTU prototype 18+1 DCS boards

  6. The Power Control Unit 1 crate in total, externally powered by Wiener LV PS • remote power switch • for DCS boards • in SM through PDBs • fully redundant : • runs 4 DCS boards • 3 LV power inputs • (A,B,C)-(2,2,4) • 2 ORed connections • to each PDB

  7. Definition of PCU partitions • each DCS board • controls the PDBs • in half of the TRD • two DCS boards • per section for • redundancy • proposal to keep • partition used for • HV, LV & Ethernet 05-13 sectors 14-17, 00-04 04 05 03 02 06 07 01 08 00 09 17 10 16 11 15 12 14 13 DCS no 0,2 DCS no 1,3

  8. C16 C17 C18 LV in racks C16,17,18 1 PCU crate 3 power inputs / crate 9 GTU crates 2 lines per GTU crate 2 power inputs / crate A B C 3 Wiener LV PS 7 power outputs / crate

  9. Power-up sequence of TRD • power up Pretrigger-system • power up GTU crates • power up PCU crate • power up PDBs (inside SM) • switch on DCS boards in PDB • power up D3.3V for SM • power up layer pairs • (A1.8,D1.8,A3.3 V) • 8. switch on ROB power • from DCS boards • the TRD is powered ( 14 ch / 4 PS) ( 18 ch / 3 PS) ( ( ( 18 ch / 10 PS) (162 ch / 72 PS) 3 ch / 3 PS) 9 ch / 5 PS) (total 224 ch / 89 PS)

  10. TRD LV power - remarks • The power-up sequence is documented here : http://alice.uni-hd.de/lv_system/more/ 02_lv_powerup_sequence_full_TRD.v03.txt • Who controls the PIM VME, shared with • the ZDC detector, located in C23_05 ?? • We still have a few unused LV channels : • … in the I/O racks, available for free !! • 3x 150A, 0..7V • 28x 50A, 0..7V

  11. LV system status at Point 2 • LV power supplies for sector 08 fully installed • 50% of power bins ready for installation • LV cabling completed for sector 08 • 50% of Wiener LV PS delivered to CERN • 50% of Wiener LV PS installed => KW 03/2007 => February 5th => mid of February => March 2nd => end of March

  12. Summary • definition of PCU partitions to be agreed on • LV power-up sequence of TRD is well defined • LV power supplies for sector 08 are installed • 50% of Wiener PS installed by end of March

  13. Thank you

  14. Backup

  15. The TRD sectors

  16. Nov 2006 : LV patch panels in the racks Flipped rack LV patch panels flipped how they should look CERN workshop now builds the right version.

  17. Wiener configuration sector 08 installation and testing takes ~1h per crate

  18. SM LV patch panels inside L3 TRD sector 14 – A-side
