Development of DAQ-SALTRO16 for TPC at Lund and Brussels: Advancements in Front-End Electronics

This document outlines the advancements in the DAQ-SALTRO16 system used for Time Projection Chamber (TPC) at Lund University. The system, based on ALICE TPC readout electronics, has successfully operated with 7680 channels during test beams at DESY. Key components include SALTRO MCMs, Kapton cables, and a new front-end design. Integration efforts with EUDAQ faced challenges due to compatibility and resource constraints. The proposal for a common DAQ interface aims to facilitate data transfer and control across systems while enhancing modularity in TPC electronics development.

Presentation Transcript

  1. DAQ-SALTRO16 activities in Lund&developments in Brussels/DESY Lund University Ulf Mjörnmark

  2. EUDET/LCTPC setup in september 2010 Low voltage Front End Electronics Kapton cables TPC Magnet

  3. ALTRO based Front End Electronics & DAQ Hardware is based on ALICE TPC readout electronics Operated reliable when taking data in test beams at DESY: 2009: February – March, July, September 2010: September, December In September 2010 the system operated with: 7680 channels (60 Front End cards) 3 RCUs, 2 DRORCs

  4. New design Backplane Front End Card Pad plane SALTRO16 MCM Multi Chip Module 16 ch ALTRO PCA16 Kapton cable PAD plane

  5. Multi Chip Module with 2 SALTRO RCU Bus card (Backplane) Read&ctrl MCM SALTRO Padplane

  6. Development in Lund DAQ-SALTRO16 Same as for EUDET/LCTPC Which has: no common DAQ interface no common TLU/DBOX trigger Modifications needed for New ”Front End Card” New backplanes MCM instead of FEC

  7. COMMON DAQ INTERFACE? COMBINED RUNNING? DAQ CORE LUND PART COMMON PART Control? implement a common server that can communicate with the DAQ process on one side, as the local server do, and with a common control on the other side. Event data transfer? Currently as local storage and sending raw binary data over network.

  8. Trigger system DBOX – TLU trigger? fully implemented if any combined running DBOX = local distribution of trigger/busy/reset Common DAQ EUDAQ:?Some work was done to integrate DAQ process with EUDAQ, but lack of time/manpower and problem with ALICE C-code together with EUDAQ C++ code interrupted it. Interface to common DAQ: Should not need to intregrate common daq code into the standalone daq core, to avoid code ”imcompatibility”, e.g.: Control: CommonServer to convert common commands to local commands Data: address/port/format/handshake to send data over network Local DAQ: Should be possible to easily swap to local running and setup.

  9. Development in Brussel/DESY Implement DRORC in microTCA: Advanced Mezzanine Card (AMC) connect ed to RCU/MCM/FEC system Development steps: Learn microTCA Make simple AMC as test New DRORC Two streams to/from DRORC: *Setup/Control *Data -> DAQ system (existing or new?) Common DAQ?
