Progress on DAQ Hardware Interface Definition Documents David

Progress on DAQ Hardware Interface Definition Documents David Cussans, Matt Graham DAQ Consortium Meeting th 18 December 2017

Introduction Need to write interface documents st Due date: 21 December DAQ has primary responsibility for: Interface to SP Photon Detection System(PDS) Interface to DP Photon Detection System DAQ has secondary responsibility for: Interface to SP TPC Cold Electronics (CE) Interface to DP TPC

Single Phase TPC CE Largest volume of data Converging on: Simple WIB ( no data conversion) 1. 2 GBit/s custom data format Transmit on multi-way fibre ribbons Multi-mode , terminated in MTP 12 connectors 80 fibres per APA Timing and synchronization: derivative of protodune system (simple to

Single Phase PDS Hardware that will be used in DUNE not clear For now assume a derivative of SSP Data volume much smaller than TPC SP PDS consortium estimates O(10 k. Hz) pixel avalanches/APA https: //indico. fnal. gov/event/14388/contribution/1/material/slides/0. pdf Assuming 5 us of 100 MSample/s at 14 bits per PA → 70 MBit/s / APA Specify up to 8 x 1 GBit/s fibre per APA No direct path from PDS to data selection

Dual Phase TPC No detail yet Proposed interface will be based on existing design 10 Gbit/s or 40 Gbit/s protocol based on UDP/IP Possible reuse for SP PDS – will need details. White Rabbit timing system Relatively small number of end-points

Dual Phase PDS Hardware will almost certainly be closely related to DP TPC Should be able to rapidly adjust DP TPC ↔ DAQ interface document for DP PDS ↔ DAQ interface

Current Status SP TPC CE : Draft circulated by Marco Verzocchi this morning. Have already been ideas passed between CE and DAQ. Rapid agreement should be possible. Some details still need to be clarified, e. g: Interfaces for integration and test-stands Latency/timing of data at DAQ

Current Status SP PDS : Draft ready to circulate. DP TPC, DP PDS Waiting for document from Dario
