Readout electronics R&D for ATLAS experiment at CERN
Område: ELEKTROTEKNIK O DATAVETENSKAP
The Instrumentation and Particle Physics Research Groups at Stockholm University are deeply involved in the ATLAS experiment at CERN (European Laboratory for Particle Physics). We use the world's largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles. The particles are made to collide together at close to the speed of light. The process gives clues about how the particles interact, and provides insights into the fundamental laws of nature.
The current LHC accelerator complex and experiments are preparing a significant upgrade (High-Luminosity LHC or HL-LHC) to significantly increase experimental sensitivity to new phenomena. The upgraded accelerator sets new stringent requirements on the electronics for the ATLAS detector. The Stockholm group is developing new electronics, introducing a new read-out strategy for the ATLAS hadronic calorimeter, a major element of the ATLAS experiment.
The DaughterBoard is an electronic board developed in-house, relying on FPGAs and responsible for collecting the data streams from the detector. It handles the high speed optical communication links for writing data to the off-detector PreProcessors and the data acquisition system.
The development of the DaughterBoard is at an advanced prototyping stage. In the present project we propose to work on the integration of the DaughterBoard with the downstream PreProcessor electronics and data acquisition system. The integration involves working on a testbench to develop a framework and user interface for configuration, testing and diagnostics of the DaughterBoards FPGAs and communication with a PreProcessor prototype. The project also involves to work in collaboration with other international institutes on the integration between the DaughterBoards and the latest prototypes of the other elements of the ATLAS data acquisition. If time allows a new daughterboard testbed will be developed.
