05/06/2016 Lab Practice: "Cosmic Wheel" 2 I propose to run a lab practice on detecting cosmic muons, in replacement of Ulrich’s similar project that was eventually canceled There’s a device meant for that, which was o designed at IN2P3 (Marseille & Bordeaux) o is built in my lab (CPPM) It’s called the « Cosmic Wheel » (« Roue Cosmique ») It’s a muon telescope: − Small, Portable, Simple, Robust We use it in outreach programs (mostly in high schools) It serves to introduce: − Particle and astroparticle physics − Illustration of special relativity − Particle detection (as a function of azimut) − Small scale module for: Trigger & data acquistion Analysis

05/06/2016 Lab Practice: "Cosmic Wheel" 3 Apparatus description: − Made of 3 plastic scintillators (30cm x 15cm x 1cm) − Each scintillator comes with: a light guide a 2-inch PMT electronics desktop running Labview My lab also produces a box for the transportation: − Size: 100cm x 70cm x 60cm − Weight: ~40 kg − Cost: ~5k€ It seems difficult (impossible?) to consider sea-freight for this, will have to ship through air-freight CNRS has a national platform for transportation called Ulisse and based in Annecy − I ask them to draw a cost estimate for the transportation to Dakar & pick-up at CPPM − In this case we’ll have to transfer money from the Team Account at CERN to CPPM to pay for the transportation CERN has also a transportation service − In this alternative, we’d pay via the T.A. − But, it’s much longer and complicated for the pick-up Ask the LOC to pick-up the device in Dakar airport and to transport it to UCAD (ITNA / Phys Dpt)

05/06/2016 Lab Practice: "Cosmic Wheel" 4 Ask the LOC: − to pick-up the device in Dakar airport and to transport it to UCAD (ITNA / Phys Dpt) − probably around late july (TBC) IOC aims: to buy the device so that it can remains after ASP2014
