Projects by non-HEPHY research groups
In addition to the projects supervised by HEPHY scientists, the HEPHY@CERN Program also offers interesting projects organised by CERN scientists. The quality of the projects and the supervision is of equal quality as those offered by HEPHY.
The exact terms and conditions (reimbursement, duration, etc.,...) may differ slightly from the projects offered and funded by HEPHY.
Performance Analysis of the CERN Neutrinos to Gran Sasso facility (CNGS)
The CNGS (CERN Neutrinos to Gran Sasso) project aims at investigating the 'oscillation' of neutrinos, specifically the oscillation from muon neutrinos into tau neutrinos. A muon neutrino beam produced by the CERN SPS accelerator is sent to the Gran Sasso National Laboratory which is situated 120 km to the east of Rome, 730km from CERN. The neutrino beam results from the decay of pions and kaons which in turn are produced by sending a high intensity proton beam of 450GeV on a complex arrangement of target, focusing magnets and decay channel. After commissioning in 2006, the operation of CNGS was started in 2007 and up to now 5.2E19 protons have been hitting the CNGS target and the OPERA experiment at Gran Sasso has registered more than 5000 neutrino interactions.
The work of the student aims at analyzing the data acquired in the CNGS beam line. In addition to all the data from the SPS accelerator, the CNGS target, focusing magnets, decay channels and entire infrastructure, the facility is equipped with numerous detectors and sensors that monitor the proper operation of the facility.
By analyzing and correlating these data the performance of the facility should be evaluated and understood in detail.
Because CNGS is a high radiation area, the performance of several components as a function of the accumulated dose provides key result for future generation neutrino beams and also the LHC.

Prerequisites: Experience with C++, the ROOT data analysis tool and also with JAVA programming would be an advantage.
Beam tests of VHMPID prototypes for the ALICE experiment
The ALICE VHMPID (Very High Momentum Particle Identification) collaboration is currently preparing a beam test of VHMPID prototypes - new Ring Imaging Cherenkov detectors enable to extend hadrons identification range at the ALICE experiment up to 30GeV/c. The student will be mainly involved in work related to this beam test preparation.
After necessary training he will participate in assembling and laboratory tests of photosensitive TGEMs and RETGEMs-innovative photosensitive gaseous micropattern detectors recently developed in our group. In the final stage of the beam test preparation the TGEMs and RETGEMs will be combined with liquid and solid Cherenkov radiators and their operation and the electronic readout will be checked with radioactive and UV sources.
The student will get a basic knowledge about the Ring Imaging Cherenkov detectors and the latest state of art achievements in gas micropattern detectors. The actual beam test of the VHMPID prototypes is scheduled for the beginning of July this year and the student is very welcome to participate in this test as well in order to get a flavor and experience in real small-scale high energy physics experiment
