SBND/ProtoDUNE System Interfaces - CE Interfaces with TPC, DAQ, and Cryostat

This presentation discusses the well-defined and documented interfaces of the cold electronics (CE) with other detector subsystems including the TPC, DAQ, and cryostat in the SBND/ProtoDUNE system. It covers the interface details, grounding, and power supplies.

  1. T. Shaw, L. Bagby ProtoDUNE/SBND CE Electronics Review 13 October 2016 SBND/ProtoDUNE System Interfaces

  2. Purpose This talk addresses Charge Question 5. Are the CE interfaces to other detector subsystems including TPC, DAQ, and cryostat well defined and documented? T. Shaw | SBND/ProtoDUNE System Interfaces

  3. SBND/ ProtoDUNESystem Interfaces • Cryostat • Warm Interface crate • DAQ • SBND: Nevis Electronics • ProtoDUNE: RCE (Reconfigurable Cluster Element)/Felix • TPC • How FE card attaches to APA frame • Wire Bias supply to APA • Racks an Power Supplies T. Shaw | SBND/ProtoDUNE System Interfaces

  4. Cryostat: SBND Interface - 3D model T. Shaw | SBND/ProtoDUNE System Interfaces

  5. Cryostat: SBND Interface - prototypes PTC/PTB/WIB T. Shaw | SBND/ProtoDUNE System Interfaces

  6. Cryostat Interface: ProtoDUNE Electronics • ProtoDUNE cold electronics to cryostat interface takes place at the cold feedthrough • Grounding details explained earlier in previous grounding talk (L. Bagby) T. Shaw | SBND/ProtoDUNE System Interfaces

  7. DAQ Interface: SBND Data and Timing/Control Fibers T. Shaw | SBND/ProtoDUNE System Interfaces

  8. DAQ Interface: ProtoDUNE Electronics DAQ Interfaces T. Shaw | SBND/ProtoDUNE System Interfaces

  9. TPC Interface: SBND Graphic • SBND CE and Geometry board stack • 3 Faraday cages over CE • Room for cabling inside the enclosure • FE card ground connected to APA frame via screws and standoffs. T. Shaw | SBND/ProtoDUNE System Interfaces

  10. TPC Interface (APA wires): ProtoDUNE Electronics • Cold Electronics interface to TPC occurs at the locations that the FE card cold boxes are plugged into the APA wire boards. • The implemented interface will provide a low impedance ground connection between the APA frame and the cold electronics board set. COLD FE DUNE wire board stack and cold electronics box T. Shaw | SBND/ProtoDUNE System Interfaces

  11. TPC Interface (wire bias): Electronics • The Cold Electronics Warm Box and feedthrough flange also provide for the pass through of the wire bias lines. • 8 SHV connectors are on the CE feedthrough flange. • The cables (RG316) need to be terminated on the APA top end on a patch panel, with single ended wires reaching various connection points around the APA. T. Shaw | SBND/ProtoDUNE System Interfaces

  12. Racks and Power Supplies DC Power for CE T. Shaw | SBND/ProtoDUNE System Interfaces

  13. Conclusion Charge question 5 Are the CE interfaces to other detector subsystems including TPC, DAQ, and cryostat well defined and documented? • All interfaces are well understood • Prototypes are being produced • Final design details will be documented over the next few months T. Shaw | SBND/ProtoDUNE System Interfaces
