Neutron-gamma discrimination Spontaneous fission source: Emission of fission fragments, gammas and neutrons γ Aim of the game: discriminate neutrons from gammas Two complementary techniques: -Time Of Flight (TOF) -Pulse Shape Discrimination (PSD) Tools of the game: scintillators + PMT -Inorganic: Na. I(Tl); Ba. F 2 -Plastics: NE 213 -Organic liquid doped with Gd/Hf Data acquisition and analysis γ -DAQ card: MATACQ (signal sampling) -Analysis: ROOT code Supervisors: Stefano Panebianco, Aurelie Bonhomme, Mehdi Drissi M 2 NPAC – Laboratory Works @ CEA Saclay - 2017

Tomography using atmospheric muons Goals: • Physics of Micromegas gaseous detectors • Assembly and characterization of a tomographic bench Supervisors: David Attié, Samira Hassani, Maxence Vandenbroucke M 2 NPAC – Laboratory Works @ CEA Saclay - 2017

Muon lifetime measurement: organic scintillators Supervisors: Claudia Nones, Matthieu Vivier, Adrien Blanchet M 2 NPAC – Laboratory Works @ CEA Saclay - 2017

Muon lifetime measurement: Water tank Supervisors: Claudia Nones, Matthieu Vivier, Adrien Blanchet M 2 NPAC – Laboratory Works @ CEA Saclay - 2017

Spectrometry and Solar light The main goal is to produce a calibrated spectrum of the Sun in the visible (400 nm to 800 nm) and to analyse it (temperature, spectral class, abundances…) Main topics : • Optical system • CCD camera, signal, noise, signal-to-noise ratio • Spectrometry, gratings, spectral resolution, light scattering • Information processing, data reduction, spectral analysis, calibration Equipment : • High resolution grating spectrometer • Large array CCD detector • Acquisition computer • Equatorial mount • Laboratory devices : spectral lamps, filters, … Supervisors: , Pascal Gallais, Eric Pantin M 2 NPAC – Laboratory Works @ CEA Saclay - 2017

Gamma spectrometry for material characterization Physics : γ-matter interaction (photoelectric peak, Compton effect…) Radioactive source Analysis of Excitation energy spectra Goals: Characterization of a germanium detector Calibration Estimation of efficiency Background noise reduction Use of NIM electronics “Modern” acquisition system Supervisors: Marine Vandebrouck, Barbara Sulignano M 2 NPAC – Laboratory Works @ CEA Saclay - 2017
