Major Component of SBND

Building & Cryogenics Support

4/27/2016 Ting Miao / SBND

Scintillator Light Detectors Cosmic Ray Tagger TPC & Cryostat x24

3

• TPC in liquid argon for neutrino interaction tracking

§ 112-ton active LAr volume, 270-ton total LAr § 4m tall x 5m wideand 4m in drift direction – two drift volumes § Cathode Plane Assembles (CPA) in the middle § Anode Plane Assembles (APAs) on the two ends § APA has 3 wire planes with 3mm pitch and spacing: vertical (y) and ±60o (U&V) § Cold electronics to have 10:1 S/N ratio and noise level below 800-electron

• Cryogenic PMTs as primary system for scintillator light collection

§ 15 photo-electron/MeV light yield from PMTs, 5ns timing resolution or better § 2nd system –DUNE-style light collection R&D – opportunity for new contributions

• Cosmic ray tagger has 4π sold angle coverage around TPC
• DAQ is based on uBooNE design and uses PMTs to tag beam events

§ More opportunity to contribute

• 120 8” Hamamatsu R5912-02mod behind TPC wire planes
• Readout with CANE v1730 (500MHz and 14 bits)
• PMTs to be TPB coated and cold tested before installation
• Opportunity for new contribution

PMT Scintillator Light Detection

8

• R&D proposal to add ~400 light guide bars side-by-side with PMTs

§ To increase scintillator light yield § To carryout performance qualification using PMT as reference

• A R&D effort closely tied to DUNE collaboration
• Fermilab is setting up a facility for TPB coating production
• New resources are needed for cabling, electronics & DAQ for SBND
• Opportunity to test other light collection ideas too

Light Guide Bar as a R&D Effort

Cosmic Ray Tagger

• Additional contributions to fill coverage

gaps on the top layers

• Need new design smaller and flexible

modules for the gaps

Scintillator Model and SiPM readout

Scintillator planes with scintillator models staged in x-y to tag cosmic background in TPC à94% muon flux coverage

11

• SBND is in detailing design stage through 2016
• TPC component fabrication design
• TPC electronics ASICs and front-end mother boards
• PMT coating and testing, readout and integration designs
• CRT production design finished in March and in production
• Cryostat and cryogenics designs and contracting
• DAQ readout designs: timing synchronization and trigger
• Detector component fabrications to finish by summer 2017
• Detector assembly and testing at Dzero to finish by Spring 2018
• Detector transfer and installation to finish by summer 2018
• Cryogenics and detector commissioning to start late 2018

SBND Detector Timeline

12

• Many subsystems need additional helps on QA/QC, cold

tests and assemble/installation/commissioning

• Big needs for additional contribution to light collection R&D
• Additional resource to increase CRT coverage
• More test-stand helps on cold electronics

§Continues effort to understand uBooNE and 35T performance §Test-stand as way for through diagnosis of detector operation issues

• Detector assembly, installation and commissioning tasks

§Both technical and physicist helps to get SBND ready in 2018

Opportunities for Collaboration

4/27/2016 Ting Miao / SBND

13

• SBND detector project is progressing very well
• Many key areas need additional helps
• SBND is the next new LArTPC physics experiment

before the big DUNE detector

• Great opportunity to gain experiences on detector

building and neutrino analysis
