The RD50 Collaboration – Radiation tolerant silicon detectors
The RD50 Collaboration – Radiation tolerant silicon detectors In 2001 the RD50 Collaboration “Radiation hard semiconductor devices for high luminosity colliders” was formed in view of the first luminosity upgrade scenarios for the LHC. It was obvious that the LHC tracking detectors would not survive the radiation damage arising from a foreseen luminosity upgrade and

The new proton & mixed-field Irradiation facility at CERN PS
The new proton & mixed-field Irradiation facility at CERN PS Irradiation is the process by which an object is exposed to radiation. Although this term is fairly generic, the performing of irradiation experiments has a very important meaning for the PH department. In fact, the PH department is deeply involved in radiation tolerance testing since

Planck mission releases first cosmology results
Planck mission releases first cosmology results The «Planck» was launched by the European Space Agency aiming at a detailed record of the microwave background radiation, a relic of the primordial plasma filling the universe during the first hundred thousand years after the Big Bang, that is still observable today. ESA’s Planck satellite has been surveying

Collecting the pieces of the Infinity Puzzle – An Interview with Frank Close
Collecting the pieces of the Infinity Puzzle – An Interview with Frank Close So what is the Infinity Puzzle about? When quantum electrodynamics was used beyond the simplest approximations it gave nonsense: infinity came as the answer for quantities that have sensible measured values. This problem was solved in 1947, when a way was found

Interview with Peter Jenni
Interview with Peter Jenni Peter Jenni's interest in physics began in a very young age. He had always enjoyed reading about physics although his high-school physics teacher wasn’t very inspiring as an educator. Studying Physics seemed as a natural choice, hence he decided to focus on experimental physics as well as astronomy and mathematics. He

Creative Collisions at CERN TH
Creative Collisions at CERN TH Creative collisions continue at CERN this summer when the internationally renowned sound artist, Bill Fontana, takes up his Collide@CERN residence for two months from June 2013. The 65 year old america artist, who studied with John Cage and is well known for turning iconic structures into sound sculptures – such
