Andrea Triossi

R&D engineer at CNRS. Design and developing of custom electronics for physics experiments

Short Bio

Research engineer at CNRS, the french Centre National de la Recherche Scientifique.
I obtained my master’s degree in Physics at the University of Padua. I completed then my PhD in Computer Science at the Ca’Foscari University of Venice working on the investigation of new methodologies allowing the hardware synthesis starting from high level languages like CHR. I had been a Fellow at CERN, the European Organization for Nuclear Research, where I worked in the CMS collaboration. I was in charge of the design and commissioning of several electronic boards for the upgrade of the Drift Tube sub-detector, like TwinMux or OBDT. I also worked at CIEMAT (the spanish Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas) and INFN (the italian Istituto Nazionale di Fisica Nucleare) on the readout and trigger system of several particle and nuclear experiments like AGATA, NEDA and WArP.

Projects

The CMS muon trigger underwent considerable enhancements during LHC run-2, which implied the redesign of the whole electronics chain. TwinMux is a new uTCA board based on a Virtex-7 FPGA that merges, arranges and fans-out the slow optical links from the muon chambers in faster (10 Gbps) links

A four-layer muon telescope has been built, employing the equipment and electronics developed for the Top Tracker (TT) detector of the Jiangmen Underground Neutrino Observatory (JUNO). The entire readout, trigger and acquisition systems have been conceived and built around versatile modular electronics embedding the latest generation of system on chips

TwinMux

Research Area

My primary research interest is in the area of reconfigurable computing applied to Experimental Physics needs. Reconfigurable computing is intended to fill the gap between hardware and software, achieving potentially much higher latency related performance than software, while maintaining a higher level of flexibility than hardware. A processing device quickly responds to changing requirements, able to demonstrate a wide range of algorithms. Hardware on the other hand has a more permanent nature, intended at performing the same task many times in a massively parallel way. The combination of low latency, high degree of parallelism and flexibility makes reconfigurable hardware architecture match the requirements typical of the trigger and read-out system of an experimental physics detector.
