Preview Numbering/Naming Scheme Coordinate System Detector Cable Plant Cabling & Cryo Services Arms “Mock Data Challenge” 5/4/2019

Numbering Scheme (for DAQ and computation) Octants: 1-8, clockwise in electron scattering mode w.r.t. the beam Detectors Locations: 1-16 Detector Type: 1=Front FPD, 2=Back FPD, 3=CED Left/Right: 1=Left, 2=Right 5/4/2019

Naming Scheme (for mechanical parts) Octants: 1-8, clockwise in electron scattering mode w.r.t. the beam Detectors Locations: 1-16 Detector Type: F=Front, B=Back, C=CED Left/Right: L=Left, R=Right Additional labels can be added (“anode”, “PMT”, “light-guide”…) 5/4/2019

Coordinate System Cartesian (xyz) System used in magnet design x=up, y=right, z=beam Cylindrical (rfz) System seems more natural in discussing systematic studies use f=0 at top to be consistent with existing xyz system used for magnet design 5/4/2019

Detector Cable Plant 512 RG58 Signal Cables 512 HV Cables 2nd Floor Counting House Service Arm Hall Patch Bases Very Long RG58 Long RG58 Service Arm HVPS Patch Hall Patch Bases HVPS Short SHV Multi-wire cables Long SHV 5/4/2019

Cryo Service Arm Design -- two long straight sections with hinges, like a human arm Current and LHe to magnet and target Hydrogen gas lines; straight sections save gas volume compared to flexible Trivial amount of cabling for magnet and target controls Needs to be bid in ~November 5/4/2019

Detector Service Arm Supports HV and signal cables out to the detector Low voltage cables for French bases Trivial amount of monitoring cables Design -- “caterpillar” cable tray on floor between rails 5/4/2019

“Mock Data Challenge” Simulation of entire data acquisition and analysis chain -- prepare software in parallel to hardware No money and few people to do this, so need to start now to give sufficient time Forces consideration of data formats and other details that might be left to last minute and not properly thought out 5/4/2019

“Mock Data Challenge” (more) Tasks: Write generators which produce simulated data streams; scalers, TDC/ADC data, slow control data; online analysis tasks tested at this level Collection of these streams into an archive (disk or tape) Analysis of archive tests offline analysis software 5/4/2019

“Mock Data Challenge” (more) Schedule identify workers schedule tasks over the next 1.5 years coordinate with arrival of relevant hardware Eventually provides framework for complete MC simulation of data acquisition and analysis 5/4/2019
