Abstract
We present an interactive game for up to seven players that demonstrates the challenges of on-line event selection at the Compact Muon Solenoid (CMS) experiment to the public. The game - in the shape of a popular classic pinball machine - was conceived and prototyped by an interdisciplinary team of graphic designers, physicists and engineers at the CMS Create hackathon in 2016. Having won the competition, the prototype was turned into a fully working machine that is now exhibited on the CMS visitors’ path. Teams of 2-7 visitors can compete with one another to collect as many interesting events as possible within a simulated LHC fill. In a fun and engaging way, the game conveys concepts such as multi-level triggering, pipelined processing, event building, the importance of purity in event selection and more subtle details such as dead time. The multi-player character of the game corresponds to the distributed nature of the actual trigger and data acquisition system of the experiment. We present the concept of the game, its design and its technical implementation centered around an Arduino micro-controller controlling 700 RGB LEDs and a sound subsystem running on a Mac mini.
Highlights
Recognizing the importance of outreach, the Compact Muon Solenoid (CMS) experiment [1] at CERN organizes an annual hackathon in which multi-disciplinary teams compete to prototype new exhibits explaining aspects of the experiment to the public
We report on the winning prototype of the 2016 edition of CMS Create
With four team members from the trigger / data acquisition (DAQ) area of the experiment, the winning team started with the idea of explaining the two-stage event selection and DAQ of the experiment to the public
Summary
Recognizing the importance of outreach, the Compact Muon Solenoid (CMS) experiment [1] at CERN organizes an annual hackathon in which multi-disciplinary teams compete to prototype new exhibits explaining aspects of the experiment to the public. In this two-day event called CMS Create [2], teams composed of four physicists or engineers from CMS and two students from Geneva’s IPAC Design school collaborate for 33 hours in the stimulating environment of CERN’s IdeaSquare [3]. Teams can draw on support from the event organizers, CMS physicists, IdeaSquare personnel and the CMS mechanical workshop, and. We report on the winning prototype of the 2016 edition of CMS Create
