Enhancements and Upgrades for Detector Setups in Run 12 and Run 13 Phases

This document outlines the necessary upgrades and additional component requirements for the detector setups in Run 12 and Run 13. Key elements include the installation of 20 additional Pb-fiber modules, sourcing new PMTs and QT boards, negotiating for VME crates, and ensuring the availability of cables and support structures. Emphasis is placed on the testing of existing modules, the fabrication of mounting stands, and the procurement of high-quality components to enhance detector performance across phases. Collaboration with partnering institutions for resources is highlighted as essential for a successful upgrade.

  1. AnDY Hardware

  2. Run 12 Layout • Detector set: • ZDCs, BBC-Y, BBC-B, PreShower phase 1, Ecal phase-1, Hcal phase-2

  3. Hcal Phase-2 (Run 12) Description: 20 additional Pb-fiber modules inserted between left and right Hcal enclosures from run 11 (phase-1) - Modules exist need to be tested - Sufficient low voltage channels for CW bases on additional modules exist in phase-1 setup Sufficient ADC channels for additional modules exist in current QT boards 24 additional RG-58 and 3 positronix spiders need to be purchased Support/lifting structures optional upgrade of low voltage system to computer control - Insert and mounts for central enclosures to be fabbed

  4. Detector set: • ZDCs, BBC-Y, Ecal phase-1, MidY, PreShower phase 2, Ecal phase-2, Hcal phase-3

  5. Mid-Y detector 80 channel scintilation counter - Scintillation plastic reused from run-11 preshower 40 additional PMTs and bases from E896 cache - 10 TACs 5 additional QT boards to be fabbed 40 additional RG58 & RG59 cables 20 additional positronics spiders - mounting stands need to be fabbed

  6. PreShower Run 13 3 planes w/ 76 detectors each - scintillator to be purchased - pmts and bases from Yale 400 on hand – need testing - # TAC boards to be fabbed - #QT boards (3*76/32<8 to be fabbed (double for TACs) - cables and patch panels - 228 LV, 228 signal, 30 positronix to buy - 1 VME crate (negotiating w/ star) - MVME 2306 already obtained - stands need to be fabbed

  7. Ecal run 13 1596 channels Glass at RHIC supplied by Jlab Need transmission tests 50 QT boards – to be fabbed 4 VME (9u) crates (negotiating w/ STAR? - 4 MVME 2306 processors Pmts supplied by Jlab need to test CW bases – to be fabbed prototype to BNL next week from Mike Ng - LV cables Cables – need 200 positronix BNC need patch panels - Stands and rail system to be fabbed

  8. Hcal Phase-3 (Run 13) 80 additional Pb-fiber modules - in negotiations with phenix - 4 additional QT boards to be fabbed - 2 VME (9u) crates (negotiate with STAR - 2 MVME 2306 processors - Low Voltage boards Cabling - Low voltage - 80 RG-58 Cables - 10 positronics spiders 2 additional racks - obtained from SVT lab

  9. Electronics for Run 13 • 9 additional DSMs (must be repaired from broken stock) • Miscellaneous cables • 1 VME crate for additional Ecal DSMs (negotiate with STAR) • 1 MVME 2306 • Network? RS232 port server?
