Advanced techniques of experimental physics

This course covers advanced techniques in experimental physics. 
A first part concerns experimental techniques related to soft matter and frugal science.
A second part deals with data analysis techniques (inference, machine learning) and their application in particle physics.

Learning of selected experimental techniques in soft matter physics, frugal science, data analysis and particle physics.

Ex-cathedra teaching, computer and laboratory work.

Part 1: Soft matter and frugal science (experiments)

In this part, students will be asked to contribute to the technical part of an open and topical experimental research question in the field of soft matter and/or frugal science. Based on a research document (scientific publications, research project,...), students will reproduce and evolve a part of the experimental device and/or the scientific tool they are inspired by in a research laboratory.  

To do so, students will be introduced to the design, fabrication and use of research objects and scientific tools, to project management techniques, to open tools and communities of practice, and to the fabrication of open science hardware. Students will work in a fablab environment with access to digital fabrication tools and will be able to rely on a transdisciplinary community of practice sharing an open, collaborative and open-source philosophy. 

The experimental object that the students will realize will be documented, for sharing with and contribution to the community, and a presentation will close this first part.

Part 2: Particle physics (data analysis)

In this part, students will learn how to extract as much information as possible from data by fitting techniques, hypothesis testing techniques, and simple Machine Learning techniques. 

Theoretical courses cover the statistical aspect of data, simulation techniques of experiments (pseudo-experiments), parameter estimation, hypothesis testing, and the different methods of Machine Learning.

The practical work on computer allows to reproduce the randomness of an experiment, to apply the techniques learned in the theoretical course, and to simulate the expected performances for these different techniques in some representative cases. We take advantage of the interactive environment of the jupyter "notebooks" with the python language. 

Contribution to the teaching profile

Become familiar with modern experimental techniques, including prototyping and modeling; contribute to the self-sufficiency of students and graduates who encounter situations where these techniques are implemented.
