ILL neutron scattering experiments consist in studying materials physics based on the scattering of neutron particles with a defined energy/speed/wavelength on a sample. These scattered neutrons are recorded on 2D detectors, with, e.g., their time of flight.

The recorded « images » are prone to parasitic "noises", following the fact that, on one hand, the neutrons beams are of low intensity and, on the other hand, from any other unavoidable external sources of noise. Thus, it becomes important to reduce the noise on the spectra through treatment algorithms.

Data can be denoised in the detector space, using traditional techniques. However, data can also be denoised in the reduced space, constituted of 4 dimensions (3 space dimensions, 1 energy one).

We would like to investigate the difference between a "detector data denoising approach" and a "reduced data denoising approach", and better understand if the data coherency in he reduced space can be helpful.

Programming will be mainly in Python using the TensorFlow library.

 

Activities of the trainee

The intern will be in charge of:

- Preparing the training data for the neural networks

- Training neural networks

- Applying to real or simulated data

- Benchmarking the results

 

Level required

4/5 year university studies in Mathematics, computing

 

Language skills

As an international research centre, we are particularly keen to ensure that we also attract applicants from outside France. You must be able to communicate in English or in French.

This internship is part of a project to extend the environment laboratory of the ILL. In order to develop the range of measurements carried out in the environment by the laboratory and thus make it more autonomous, the latter has equipped itself with a tube furnace intended to proceed with the preparation of samples taken from the environment (samples organic products such as herbs, milk, etc.). This preparation is a prerequisite for measuring any organically bound tritium present in this type of sample. The course is divided into two parts: - discovery of the profession of environmental monitoring technician. This stage of the internship is important to understand the context of environmental monitoring of a nuclear site, its regulatory obligations in this area and the reason why the laboratory wishes to install this furnace. - develop the method for preparing biological matrices in order to measure the organically bound tritium present in this type of sample. This second part is conditioned by the actual installation of the oven in the laboratory and the guarantee of its operation.

 

Activities of the trainee

For the discovery part of the profession of environmental monitoring technician, the trainee will take part in sampling operations in the environment and may, if necessary, deepen this knowledge by carrying out radioactivity analyzes on samples that he will have taken. This activity is part of the regulatory program for environmental monitoring and must be carried out in compliance with the ISO IEC 17025 standard (and applicable standards in the field). For the method part, the trainee will rely on the methodology described in the standard "NF M60-824 Nuclear energy - Measurement of radioactivity in the environment - Test method for the analysis of tritium in free water and organically bound tritium in environmental matrices "to develop and validate the method within the laboratory, define and write the preparation protocol by carrying out tests on environmental matrices and in intercomparison with other operators' or private laboratories . The preparation protocol must also include the calculation of the uncertainty linked to the preparation which will serve as the basis for the calculation of the overall uncertainty of the measurement. This internship would be suitable for a 5th university year level looking for an internship +2 +3 level in his course.

 

Level required

3 year university studies in Physical measurement or Chemistry, 1st year Engineering school in chemistry or other
