sPHENIX Update

1. sPHENIX Update • Update • The Project • SC-Magnet • HCal • EMCal • Tracker Edward O'Brien

2. Update • DOE sPHENIX Science Review held Apr 30 @ BNL • Very positive outcome. No action items or recommendations • BaBar SC-Magnet arrived at BNL in Feb 2015 • All ancillary magnet equipment has now arrived from SLAC (magnet PS, dump resistor, control racks, cryo lines…) • Magnet passed its warm acceptance test • Detailed plans for a cold low-power test followed by a full-field test are underway • Engineers are working on sPHENIX SC-magnet, HCal, EMCal, Calorimeter Electronics, Infrastructure, and Installation • Engineering Progress on Tracker needs to begin • Project Management team has been assembled w/ exception of Chief EE • Irina Sourakova will handle Project Controls • R&D for the HCal and EMCal with goal of beam test at FNAL Apr 2016 • Vendor and institution site visits have started with some related to Outer and Inner HCal scheduled for the next few weeks • Berndt Mueller has asked us to prepare for an Internal Cost and Schedule review in the Fall 2015 Edward O'Brien

6. Other Project Issues • Bob Ernst and I met with Diane Hatton last week about starting Project Controls training for Irina S. She was very supportive of our plan in general with the exception of giving Manta Ray another big consulting contract like ATLAS has. Using Hammer seems OK though. • I have to present sPHENIX to the BNL Project Oversight Board Thursday May 21. • Will start to invite Lloyd Nelson of BHSO to attend sPHENIX Management meeting once/month. • Working on Resource-loaded schedule with key personnel identified, for input to Jon by June 1.

7. SC-Magnet • Warm acceptance test is completed. Everything checks out. • Low power cold testing plans well under way • Meeting with BNL’s Labwide ES&H Committee May 22 for test approval. • C-AD and SMD people have started to assemble the slides for the review. Kin is organizing the review presentations. • Review of the chimney/valve box extension using the sPHENIX Magnet Review committee scheduled for May 14. Jim Mills is organizing this. • Plans for Full field test and temporary flux return are progressing. Jon Hock and Dave Phillips are leading this. Edward O'Brien

8. SC-Magnet Acceptance Test • SC-Magnet Acceptance Test Complete in 912. All is OK • Tests Performed by Mike Aneralla and SMD crew with C-AD help • Hypot test • Impulse tests • He Leak check • Inductance measurement Edward O'Brien

15. EMCal Design and R&D • C-AD engineer Chris Cullen is working with Craig Woody, Sean Stoll and Bill Lenz on EMCal design • Efforts to produce spacal modules also ongoing at UIUC, UCLA and THP EMCal Tower @ BNL Edward O'Brien

16. Making Projective EMCal Modules The current technology developed at UCLA can be used to produce 1D tapered modules 1D tapered module Mesh screens 2D tapered module J.Huang BNL Two slotted wire frames allow two independent rotation angles Edward O'Brien

17. Mass Production of Modules • Tungsten Heavy Powder has been trying to build 1D modules and has been making reasonably good progress • Problems with gluing and getting good uniformity and consistency • Experiencing delivery problems with things like epoxy, meshes, etc. • However, they have not significantly increased the efficiency for module production beyond what Oleg Tsai has done (still takes more than one day per module) • Goal is to first produce acceptable modules and then try to improve efficiency • Once they achieve this, we would then transfer the technology developed at BNL for producing 2D modules to them ( ~ August) • Hopefully they would then apply their improved production techniques to produce the 2D modules THP Goal would be to have all modules for prototype(s) by this fall Edward O'Brien

18. SPACAL module production at BNL • We have produced 4 modules at BNL so far • We are holding off on producing more until the new 2D taper meshes/screens come in, possibly this week • We have sufficient fiber, tungsten powder, screens, epoxy to produce another 12 modules • We feel that we have worked through most of the issues and understand the process well • Some issues that we have dealt with: • air bubbles/tungsten powder inclusions in clear epoxy region • Full and uniform penetration of epoxy through the tungsten powder • Uniform surface characteristics • Uniform fiber distribution • End surface finish/polish • One module is currently in the PHENIX IR as part of the SiPM radiation damage testing. S.Stoll Edward O'Brien

19. Module Production at Illinois Initially started trying to produce 2D tapered modules two at a time (bow tie design) • New postdoc Vera Loggins is now working on module design and production. Spent 1 week with us here at BNL • Personnel: 2 UIUC techs+Anne Sickles+postdoc • Currently planning to try and produce 1D modules using Oleg’s technique as a next step Edward O'Brien

20. Design underway for sPHENIX HCal prototype Full-scale Outer mechanical prototype Full scale Inner mechanical 5 tower x 5 tower performance prototype for beam test at FNAL Full scale mock-up (wood or plastic) for fit, cabling, etc. Goal is for a beam test of the performance prototype Apr 2016 Site visits to steel vendors start this week Strecks in Albany tomorrow Atlas steel in Chicago later this month Next week visit to GSU to inspect machine shops their for Inner Hcal work HCal

21. HCal Design Detailing near complete for full scale HCal Prototype Edward O'Brien 21

22. Performance Demo Prototype (Beam Test) – Outer & Inner HCal Outer HCal Inner HCal • Outer & Inner HCal: 25 layers, 5 tiles per layer = 5 “towers” (1.5 m x 0.9 m) • Performance Prototype needs to be steel but does not need to be 1006 magnet steel; • Will accommodate 5 adjacent tiles from the interior, far end or anywhere In between • Full scale mechanical prototype will be built for evaluating manufacturability, handling, mechanical properties, etc.; • ½ length wood (or equivalent) HCal mock-up will also be fabricated to develop tile insertion, handling, light collection and cable routing and data collection management techniques • Expect to design, procure and assemble ready for beam test in 44 weeks Edward O'Brien 22

23. Two sPHENIX Tracker Options Edward O'Brien 23 Now holding bi-weekly meetings on the Tracker detector Two Tracker Options: • All silicon Tracker. Two layers of pixels plus 5 layers of strips (reference design in proposal) • A Si/TPC hybrid. Two layers of pixels plus TPC 30 cm < r < 80 cm • SiTracker option has a proposal in to JSPS, not yet approved. RIKEN R&D • Hybrid option has funding for TPC R&D from EIC R&D program • The all Si Tracker design has what has been presented to outside committees to date. • A Project file exists for the Si Tracker. • Would like to bring the hybrid solution to an equivalent state of project planning. • This implies a cost estimate for both materials and labor • We need to develop a concept for the electronics for both Tracker options • We need to identify manpower, especially engineering manpower, for the Tracker, both options
