  1. AnDY at IP2 Infrastructure Requirements & Experimental Construction Charles Folz, BNL

  2. Expanded Calorimetry • Upgrade of Hcal requires removal of existing modules, replacement of current base/foundation, and fabrication of azimuthal support • This model shows the design used for Run 12; Run 13/14 will be similar in design, but incorporate an expanded array: Charles Folz, BNL

  3. New PMT Supports • After assembly of new array, new aluminum cover panels will be installed and PMT guides will be fabricated in CAD Tech shop – this process was performed this past fall for the Run 12 modifications. The 2 new PMT supports were 5x2 arrays and required custom fitting and are now in service: Run 12 PMT Support plate Charles Folz, BNL

  4. HCAL Costs • Hardware & Misc materials purchases apx .$3,650 • BNL Central Shop fabrication costs apx. $11,000 • CAD Techs, Electricians & Rigging to provide remainder of support for assembly, modification and setup Charles Folz, BNL

  5. ECal • All calorimetry required to construct Ecal has been acquired and is currently on-site at 1002B: Charles Folz, BNL

  6. Ecal Modifications • Substantial efforts are required to assemble the lead-glass calorimetryin an azimuthal array: Charles Folz, BNL

  7. Azimuthal Array Support & Thomson Rail • In order to provide structural support around the beam pipe, two semi-circular stainless steel braces will be installed at the center of Ecal. These will be supported by off-the-shelf carbon fiber shapes at the end facing the IR, and by a conventional aluminum fabrication at the opposite end. This design has been checked for strength and modeled…. • In order to allow lateral movement, the array will be supported on rail type linear motion bearings… Charles Folz, BNL

  8. Mechanica Analysis/ProE ModelMaximum deformation of .001058” (Deformation is exaggerated) Charles Folz, BNL

  9. ECal Installation • Hydraulic lift table has already been acquired and tested • Miscellaneous hardware, Thomson rail and raw materials purchases estimated to cost $16,000 • Shop fabrication another $6,000 • CAD Tech labor is required to install and setup the lift tables and shims for the array as well as miscellaneous item fabrication Charles Folz, BNL

  10. New Ecal Charles Folz, BNL

  11. Ecal Support Calculations for AnDYCalorimetry Ecalcells wt=5.25 lbm, No of Cells in detector: =1632 Total weight of Ecal=8568 lbm or.... 4.28 tons Each lift table will be required support half of this weight or 2.14 tons The lift tables are rated at 12,000lb each, more than sufficient to support the calorimeters. No of cells supported by each brace: 40 Load on brace: = 40x5.25=210 lb This load is easily supported by the proposed SS brace... Charles Folz, BNL

  12. Pre-Shower • Scintillator frame to be field assembled • Consists of three panels of four “quadrants”, framed in aluminum “track” to accept sandwich panels composed of carbon fiber sheet and scintillator. • Costs consist mostly of raw materials; estimated (catalog prices) at $28,000 • Custom fabrication and assembly by CAD techs Charles Folz, BNL

  13. Single Quadrant Panel Design Charles Folz, BNL

  14. Subtotals for Calorimetry So far we have $81,085 – including contingency of 40%: Charles Folz, BNL

  15. Phobos Dipole This magnet will require: • Opening of the aperture; new upper half support posts from Central Shops • Updated power supply from CAD • Cooling water system – using tower planned for installation to support CeC • Installation by CAD Techs,Electricians & Riggers Charles Folz, BNL

  16. Power Supply • Explored the option to use power supply from Phobos installation; this unit was determined to be unreliable and is no longer available • A new power supply can be assembled from components available to CAD Power Supply Group at minimal cost given sufficient lead time. • Working part-time, a replacement power supply can be assembled in approximately 4 months . • It is anticipated that parts purchases should be minimal • From Wuzheng Meng’s field calculations, we have the following: • “The required ampere-turns per pole, both for PHOBOS and for AnDY are the same: 172800 Ampere-turn (per pole).” • “If we look into the conductors (on the drawing), there are 96 turns (single) conductor per pole. Since PHOBOS was powered in pairs, then we can say that the current from the power supply was 3600 A; and the total ampere-turn per pole was 3600 A x 48 = 172800 A-T per pole.” • “In AnDY case (with expanded gap size), I used the same number of the ampere-turns to get the field map with the peak field around ~1.3 Tesla. Now, I am using 3600 A as the operating current to calculate the inductance of the magnet.” Charles Folz, BNL

  17. Dipole Installation • It was requested to expand the dipole aperture by a factor of two, from the existing gap of 15.7 cm to 31.4 cm • In order to accomplish this, the existing corner posts will be replaced with new posts fabricated at BNL Central Shops from 8” Sch 8o steel pipe with flat steel base plates. • Material cost estimated at $400 and labor would be approximately $400/pc for a total of $2,000 • Reassembly will follow the same method as original, Survey to obtain as-constructed dimensions. • Support will provided by conventional jacks Charles Folz, BNL

  18. Dipole Installation - Continued • Dipole to be physically installed Summer-Fall 2012 • Installation of CeC required cooling tower will be leveraged to provide for cooling water • A 3MW tower from (PTR) is available and planned for installation on the pre-existing footings remaining from Brahms installation • Installation of piping and wiring is outlined in the following budget sheet…. Charles Folz, BNL

  19. Dipole Budget for 2013-14 Charles Folz, BNL

  20. Preliminary Layout of 1002 IR Charles Folz, BNL

  21. Summary • Preliminary design work to bring the AnDY experiment to useful function has been completed • Detailed design work remains, specifically in the area of calorimetry • Hcalazimuthal arrangement is proven design – in service • CAD labor should be sufficient to assemble the necessary components (including power supply) from off-the shelf and custom made parts outlined previously • Calorimetry budget is estimated at $81,000 • Dipole installation is estimated at $150,000 • Close coordination will be necessary to allow completion of AnDY while not impeding CeC progress Charles Folz, BNL
