Programming of a camera based metrology system
Internship (Ref. DIFF_2 )
SALSA is a neutron diffraction instrument to map stress fields within engineering components of any kind, between cm and metre size. Sample alignment requires very high precision and is crucial for the performance of all types of experiments.
The challenge is to align these components with a precision of 20 microns reproducibly on the sample stage. For this purpose SALSA is equipped with a camera assited metrology system. Basic functions, such as image recognition, have already been programmed in-house. During this internship, routines for (semi-) automatic alignment shall be programmed. For this purpose, camera coordinates shall be transferred into instrument coordinates, and, taking into account the actual position of the instrument, commands for sample positioning shall be generated. Programming experience in C++ is required.

Characterisation of the background for the future RICOCHET experiment
Internship (Ref. NPP_6 )
RICOCHET is a new experiment aiming to measure coherent elastic neutrino nuclear scattering (CEνNS) of reactor antineutrinos with cryogenic detectors. It is being prepared by an international collaboration, including the LPSC Grenoble, the i2pi Lyon, and the Institut Laue Langevin where the experiment will be installed. A major challenge for the experiment is to reduce and control the background from cosmic rays and surrounding experiments. For this purpose, an active muon veto made of plastic scintillators and a passive shielding made of lead and polyethylene are currently being installed on the future site of RICOCHET. The internship has the objective to measure and understand the remaining background and comprises experimental and phenomenological tasks. The experimental part consists of data acquisition with different types of detectors (e.g., the muon veto, a Ge detector for the gamma background, 3He neutron detectors for the neutron background) and data analysis. The phenomenological part includes Geant4 simulations to interpret the results and extrapolate them to the future RICOCHET detectors..
Activities of the trainee:
Experimental part: Measurements with different detectors (examples: Ge detectors, 3He detectors, plastic scintillators): installation, data taking, data analysis. Phenomenological part: Geant4 simulations of cosmic radiation and reactor background.
Level required:
5 year university studies in Physics
