Weekly DUNE SP Detector Integration Engineering Meeting Slides 11/06/18 Kyle Zeug • Solid model goals, strategy and methods • N‐S Section Four Corner Detail • E‐W Section Four Corner Detail
TPC Solid Model: Goals • Verify the TPC meets all requirements from the science community • Driver of interface drawings • Understand changes and additions so they can be implemented as designs become final • Single source for tracking detailed design of assemblies from all organizations • Identify and correct fit and clearance issues prior to cutting material • Maintain an appropriate level of detail that is specific to integration and installation. File size and processing time must not be prohibitive
TPC Solid Model: Strategy • Begin with defined bounds of the cryostat • TPC installation will occur at the warm state and the TPC model reflects this • Add TPC components as designs progress and become available • Update TPC components as designs progress • Constraints are created in a manner that is consistent with component installation
TPC Solid Model: Strategy • Constraints are added if they can be backed up by sound engineering judgement • The reference dimension tool allows notes to be added at undefined locations. Examples: • Row of APA stack assemblies distance to cryostat. (note end walls are not currently included in the model) • Service floor distance to vertical piping • The intent is to limit assumptions • As definition is added undefined reference dimensions will be removed
TPC Solid Model: Methods • To keep file size and processing time reasonable one cell of the TPC will be modeled with higher detail • Repeating cells will be represented by models with less detail • Features that are critical to installation and integration must be shown. Examples: • SHV on APA stack assembly • Latches

Other Thoughts • Inside dimension between top and bottom field cage profiles = 12,100mm • CPA top to bottom hinge = 11,947.3mm
