This talk is not a summary of costs for conventional facilities This talk is Review of conventional facilities used by CDF Discussion of status of systems moving forward A request for specifications so we can coexist with IARC Possibly get some things paid for before ORKA is funded Context Fermilab is planning a rehab of the CDF assembly building in FY14 We should make sure ORKA’s needs are met or we will pay later 10/17/ Conventional Facilities

10/17/2012Conventional Facilities 3

CDF had counting rooms on three floors Third floor: low quality computer room Convert to IARC offices First floor: easy access to high-bay areas Use for technician space Second floor 70’x22’ Maintain aisle, so probably use only 18’ 225A 3-phase electrical panel Service cable to add two more if needed Electronics cooling water loop Cable raceways to first floor with easy access to penetrations to collision hall (see drawing) Plan for ORKA shifts in IF control room in high rise 10/17/2012Conventional Facilities 4

10/17/2012Conventional Facilities 5 Cable penetrations 4 or 6 per location 14”x6”each Proposed Assembly Area

10/50 ton crate West high bay and deep pit to be used by IARC We need to reserve space at south end of pit for a transport cart to move ORKA package or components into hall 10/17/2012Conventional Facilities 6

All CDF muon elements will be removed Central Detector to be moved 10’ north for ORKA Requires new cryo connections, floor pads Electrical Power Electronics cooling loop Maintain racks in 8 corners Facility for 3 crates per corner with 10A 208 three-phase power each Cooling fans with air-water heat exchangers Do we need a crane for assembly? What are the fire suppression needs? Can/should we keep the existing Halon spheres? 10/17/2012Conventional Facilities 7

Solenoid operated at 14.1 T 1.25T should not be a problem Field map exists Some modification expected if we proceed with current plan for mounting rails Field probably not reversible Power supply intact Plan nearly complete for preservation Requires sign-off by experts Probably will fill vacuum vessel with dry nitrogen 10/17/2012Conventional Facilities 8 Work needed to resurrect New current and cryo feeds for new position, also power for pumps, etc. Update controls Do we want to repair the Watt can? Risk vs. benefit analysis required

Cryo system intact Equivalent to one Tevatron satellite fridge Relies on Micom compressor in B0 service building Cooled with pond water Control system must be updated New ODH system also needed IARC will need additional refrigerators for their program Not wise to share even if capacity exists Need to spec out needs on both sides 10/17/2012Conventional Facilities 9

10/17/2012Conventional Facilities 10

Three Main Feeds Building Power Lights, receptacles, crane, etc. Misc. panels around high-bay and collision hall Utility Power Solenoid Trailers 225A each to 1st and 2nd floor counting rooms 10/17/2012Conventional Facilities 11 Experimental Power Collision Hall (800A) Assembly Hall Pit (IARC) Open circuits (IARC) Feed for two 225A circuits in 2nd floor counting room Need transformers

CDF had facilities to serve many wire chamber systems Control and measurement components removed Extant infrastructure Tube trailer connections and mix shed over berm Large storage tanks behind building Supply lines from gas platforms to CH Two large LN2 dewars For cryo and interting flows 10/17/2012Conventional Facilities 12

10/17/2012Conventional Facilities 13

Chilled water (CW) Cooled by two 185-ton Trane chillers Can use PW/ICW heat exchanger for low load periods Serves HVAC and secondary cooling loops Plumbing to Mechanical Rooms, Assembly Pit and 3 rd floor counting room Pipes to 1 st and 2 nd floor cut – can reroute if needed 10/17/2012Conventional Facilities 14

Ponds empty from A2 to B3 Require extensive reconstruction Needed for beamline? Pumps intact Used for LCW Previously used with compressors for CW ICW can be used in place of PW Single pass Don’t know capacity 10/17/2012Conventional Facilities 15

Low conductivity water (LCW) Cooled by PW/ICW Water-water tube heat exchanger is very old Original capacity was 650 kW Could not keep up with conventional test magnet during Run II Solenoid is 150 kW Shared with IARC Plan to reuse plumbing in assembly pit Currently no power to pumps Motor control center requires rebuild Should be part of IARC rehab project 10/17/2012Conventional Facilities 16

10/17/2012Conventional Facilities 17

Electronics Cooling Water (ECW) Secondary loop off CW Serves collision hall, 1 st and 2 nd floor counting rooms Racks on detector have water cooling Pumps in alcove of pit No sharing with IARC Other Pluming from SVX and ISL water-glycol system from alcove to collision hall can be repurposed Rest of system is obsolete SUVA system for COT has been claimed by mu2e 10/17/2012Conventional Facilities 18

10/17/2012Conventional Facilities 19

Two separate systems Assembly Building: Metasys Collision hall : CDF Slow Controls High rate of recirculation to avoid stratification Both must be replaced Must include capability for ODH and flammable gas protection CDF priorities Pressure to protect drift chamber Temperature Humidity Avoid HV breakdown 10/17/2012Conventional Facilities 20

What are ORKA’s cooling loads? ECW, LCW, HVAC Collision hall HVAC requirements? Gas delivery requirements? Safety issues? ODH, flammable gas Nitrogen inerting? Large volume inside solenoid Installation Plan? Do we need crane(s) in the collision hall 10/17/2012Conventional Facilities 24
