Doctoral student in Solid Mechanics and time-of-flight neutron tomography Full-time

Doctoral Student In Solid Mechanics And Time-Of-Flight Neutron Tomography

Lund University, Faculty of Engineering, LTH, Construction Sciences

Lund University was founded in 1666 and is repeatedly ranked among the world's top universities. The University has around 46 000 students and 8 500 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition.

Description Of The Workplace

The Division of Solid Mechanics was the first department established at LTH and is now part of the Department of Construction Sciences. The division operates in an international environment and has connections with research organizations and companies both nationally and internationally. Today, the Division of Solid Mechanics consists of approximately 25 employees, of which around 15 are PhD students. The work environment is open and welcoming, striving to provide each employee with the opportunity to develop personally and professionally. The field of solid mechanics relates to methods and principles aimed at understanding and modelling the mechanics of deformable bodies. Solid mechanics is a core discipline in mechanical engineering and is of fundamental importance to many other related disciplines. The questions addressed in solid mechanics have high relevance for industrial applications in many sectors. Research in solid mechanics at LTH is specifically focused on constitutive mechanics, numerical methods, microstructural mechanics, structural optimization, and experimental methods. The department also has strong activity in X-ray and neutron methods for materials research.

Being A Doctoral Student

As a doctoral student, you are both admitted as a student and employed at Lund University.

As a doctoral student, you will be trained in a scientific approach. In short, you will be trained to think critically and analytically, to solve problems independently using the right methods, and to develop an awareness of research ethics. In addition, you will have the opportunity to work on projects, to develop your leadership and pedagogical skills. Throughout your studies, you will be guided by supervisors. Doctoral studies end with a thesis and a doctoral degree. More about being a doctoral student at LTH on lth.se

Subject And Project Description

The imminent startup of the European Spallation Source ERIC, ESS, represents a fantastic opportunity for science, opening new avenues for investigating and understanding the internal structures and processes of materials and to understand our past and the history of our universe. Neutron imaging (radiography and tomography) will be possible at the Odin instrument and, coupled with the unique nature of the ESS source, will provide new perspectives on materials and structures through the possibility for hyperspectral, multidimensional images containing intricate details on the distribution of chemistry, composition, deformation and temperature. This project is part of the “Pillars for Imaging” initiative that aims to demonstrate the capabilities and support developments of the ecosystem around the Odin instrument. Furthermore, the project will contribute to building a foundation for science with neutron imaging at ESS from beam-on-target to beyond 2030, by establishing and demonstrating key 3D tomographic reconstruction methods to exploit the capabilities of Odin to address scientific questions and challenges across a wide spectrum of science.

Work Duties

You will primarily devote yourself to your doctoral programme, which includes participation in research projects as well as third cycle courses, seminars and conferences.

The work duties will include:

• 3D/4D Tomographic reconstruction of multi-/hyperspectral time-of-flight (ToF) neutron imaging data,
• exploration of best strategies for tomographic reconstruction of ToF transmission data and noise mitigation approaches,
• tomography and ToF data fitting algorithm development,
• forward modelling of neutron/x-ray tomography at Odin,
• development of and involvement in early science experiments at Odin,
• materials analysis using ToF-tomography and dual x-ray/neutron tomography using Odin (including image reconstruction and data analysis).

The duties may also include participation in teaching and other departmental work (however, a maximum of 20% of working hours).

Qualifications

To be eligible for admission and employment as a doctoral student, you must fulfil the requirements below.

Admission requirements

A person meets the general admission requirements for third-cycle courses and study programmes if the applicant:

• has been awarded a second-cycle qualification, or
• has satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second cycle, or
• has acquired substantially equivalent knowledge in some other way in Sweden or abroad.

A person meets the specific admission requirements for third cycle studies in Solid Mechanics if the applicant has:

• at least 45 credits in courses relevant to the subject, or
• a MSc in Mechanical Engineering, Engineering Physics, Engineering Mathematics, Civil Engineering or related fields.

Additional requirements

In order to complete the doctoral programme in question, the following are also required:

• good knowledge in physics, maths and computer programming,
• curiosity about research and teaching, in general, plus motivation for the particular research project,
• ability to work independently and to formulate and tackle research problems,
• creativity with a good ability for cooperation and networking,
• good written and oral communication skills,
• very good oral and written proficiency in English.

Other qualifications

For the doctoral programme in question, the following are considered as other qualifications:

• interest and experience in imaging methods, materials characterisation and data analysis,
• knowledge of neutron imaging techniques (in particular, neutron radiography, tomography and hyperspectral/time-of-flight),
• experience in computer programming in Matlab®, python, C, or equivalent,
• knowledge in image analysis and computer programming,
• a thesis (e.g., master's thesis) at an advanced level within the subject area.

Consideration will also be given to how the applicant, through experience and skills, is deemed to have the abilities necessary for successfully completing the third cycle programme.
