CERN Accelerating science

Lecture 2: DAQ - Filtering Data from 1 PB/s to 600 MB/s

Thursday, 7 July, 2016 - 15:00 to 16:30

Brief description: 

• This is the story of the physics signal from the detector to tape

• The level is undergraduate and targeted at non-specialist students (originally developed for physicists)

• The aim is to explain important concepts and terminology

• We will discuss electronics, trigger, data acquisition and related computing

• Topics are related, no 100% separation between the 3

• Trigger & DAQ do not live in isolation: context and more details for example in

Speaker's short bio: Niko Neufeld was born and studied in Austria. He holds a degree in engineering physics from the University of Technology in Vienna Austria and a PhD in particle physics. Since 2000 he has been working in the field of high-speed data acquisition and embedded processing. He has co-designed the data acquisition system of the LHCb experiment, a facility to study the minute differences between matter and anti-matter sifting through almost 70 Gigabytes of data / second. He is now in charge of the upgrade of the LHCb DAQ, which will increase the data-rate by almost a factor 50. Mr. Neufeld has published on numerous topics of high-speed networking, physics data-processing and embedded systems. He is a staff scientist in the experimental physics department at CERN.
