SasView (www.sasview.org) is an open source software package and one of the leading tools for the analysis of small angle scattering data. It is developed and maintained by an international team  from more than 10 facilities and organizations, including the ILL. However, it relies on the effort of volunteers and external funding in order to get the resources to add major new functionality. Therefore, there are several small and mid-term projects that would benefit from the dedicated work of a trainee during a period of 5 or 6 months. This internship is very well adapted either to a student with an scientific background (Physics/Chemistry/Maths) and some programming knowledge who would be interesting in developing his/her abilities in software development or to a software engineer/computer scientist interesting in applying his/her knowledge to scientifc problems. Depending on the trainees' profile, two main projects can be proposed: Refactoring of the graphics and the user interface to extend the software capabilities (mainly software engineer work) or rewriting part of the models library to allow SasView to handle non-centrosymmetric particle models (more knowledge of physics required). Any improvement in any of those two topics would greatly enhance the impact of SasView in the community..

 

Activities of the trainee:

1. Get familiar with the code base (based on Python 3 and Qt5/PyQt5, with most of the scientific models written in C).

2. Interact with a broad international team of contributors through fortnightly video meetings, emails, mailing lists, Slack channels, GitHub issues and comments in order to improve the code in the areas mentioned above, as well as to fix other minor issues and bugs.

3. Participate in the code review process by submitting his/her code for review and performing reviews on other developer's code.

 

Level required:

 5 year university studies in Software engineer or physics

 

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.

 

Notes:

This post is an internship with a maximum duration of 6 months

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.

For some experiments, classical denoising methods cannot provide acceptable results. Recent Deep Learning breakthrough, have brought new denoising methods, some of them being model-agnostic and not requiring any statistical noise model (Noise2Noise, Noise2Void, etc.). Although these techniques were primarily focused to medical imaging, some similarities with our detector images motivate us to try using them on our neutron spectra to improve our denoising process.

The goal of the training is to compare these new methods to classical denoising/filtering methods based on ILL detector data. Publications (with their accompanying code libraries) have been identified and the real or simulated data are already existing at the ILL. 

 

Activities of the trainee:

The intern will be in charge of:
- Preparing the training data for the neural networks
- Training neural networks while controlling the loss function
- Applying to real or simulated data
- Benchmarking the results

Programming will be mainly in Python using the TensorFlow library.

 

Level required:

 4 year university studies in Informatics, mathematics

 

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 an extension project of the ILL environment laboratory. In order to develop the panel 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 for the preparation of samples taken from the environment (biological samples such as as herbs, milk, etc.). This preparation is a prerequisite for measuring any organically bound tritium present in this sample type.

The course is divided into two parts:

  • the discovery of the profession of environmental monitoring technician. This stage of the internship is important to know the context of environmental monitoring of a nuclear site, its regulatory obligations in this domain and the reason why the laboratory wishes to install this oven.
  • monitor, in conjunction with the SAE (Development and Maintenance Department), the work prior to the installation and commissioning of the furnace service in the laboratory.

 

Activities of the trainee:

For the discovery part of the profession of environmental monitoring technician, the trainee will participate in operations taking samples from the environment and may, if necessary, deepen this knowledge by carrying out

radioactivity analyzes on samples taken. This activity is part of the program regulatory oversight of the environment and must be carried out in compliance with the ISO IEC 17025 standard (and standards applicable in the field). For the game work the trainee will be responsible for monitoring the effective performance of the work by the subcontracting companies in liaison with the SAE. To this end, he will participate, if necessary, depending on the degree of progress of the preparation carried out by ÏILL, consulting companies, drafting prevention plans in conjunction with safety engineers, welcoming them on site, monitoring and acceptance of each phase of work. The works concerned are: fitting out the premises. the power supply, the supply of gaseous fluids for combustion, the extraction of fumes, the window and the damper detectionlsafety. At the end of the work, the trainee will, if necessary, carry out the functional test of the oven in conjunction with the vendor.

 

Level required:

 2 year university studies in Process engineering or physical measurements

 

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.
