Internal Research Fellow PostDoc in Radiation Hardness Assurance processes for COTS EEE Components

2017-09-20 17:12:14| Space-careers.com Jobs RSS

Research Fellowship opportunity in the Directorate of Technology, Engineering and Quality. ESA is an equal opportunity employer, committed to achieving diversity within the workforce and creating an inclusive working environment. Applications from women are encouraged. Post Internal Research Fellow PostDoc in Radiation Hardness Assurance processes for COTS EEE Components This post is classified F2 on the Coordinated Organisations salary scale. Location ESTEC, Noordwijk, The Netherlands Description The Component Materials Physics Chemistry Evaluation Standardisation Division, within the Product Assurance and Safety Department, is responsible for the evaluation, qualification and standardisation of Electrical, Electronic and Electromechanical EEE Components and Materials used in ESA spacecraft and Standardisation Activities. The division provides direct and indirect engineering and product assurance support to ESA projects and the European Space Industry. The work of the division covers a broad range of engineering and management activities via the reliability assessment of existing and new component technologies and part types, the definition of test standards and test methods, development of application and procurement requirements, technology and component development support, reverse engineering and failure analysis performed in a state of the art onsite laboratory including radiation test facilities and delivery of data to end users via public and restricted websites and databases. The focus is on the effects of exposure to the space environment such as vacuum, temperature, particles, ionising and nonionising radiation. Interested candidates are highly encouraged to visit the ESA website. Fields of activitiesresearch Overview of the field of research proposed Introduction EEE components flown on ESA spacecraft have to operate in the inhospitable space environment. An important part of this environment of concern to electronic components is the space radiation environment. The space radiation environment is composed of a large variety of particles with a complex energy spectrum. Particles of concern are electrons, protons and heavier ions. These particles may adversely affect electronic components via cumulative effects or transient effects. In the worst case, an electronic component may exhibit a catastrophic failure when exposed to the space radiation environment. Various Radiation Hardness Assurance processes are applied to ensure suitability of EEE components for flight on ESA spacecraft. These include Radiation screening characterisation Radiation evaluation qualification Radiation hardening work Development of irradiation test methods Development of Radiation Hardness Assurance standards Radiation Hardness Assurance also includes work in the field of dosimetry, inflight EEE component radiation experiments, inflight anomaly investigation, work at particle accelerator irradiation test facilities, etc. Research area Specific research area concerns improvement of the understanding of the Radiation Hardness Assurance processes for CommercialOffTheShelf COTS EEE Components for Total ionizing Dose, Displacement Damage and Single Event Effects. This involves the characterisation of various EEE components during and after irradiation tests with the objective to improve existing methodologies and possibly to demonstrate new approaches. The research area also includes development of InFlight Cubesat payload experiments in the area of Radiation Hardness Assurance Verification. These experiments aim at measuring EEE Component performance when exposed to the natural space radiation environment. Technical competencies Ability to conduct research autonomously Breadth of exposure coming from past andor current researchactivities Researchpublication record Knowledge relevant to the field of research Interest in space and space research Ability to gather and share relevant information Behavioural competencies Innovation Creativity Continuous Learning Relationship Management Self Motivation Communication Problem Solving CrossCultural Sensitivity Education Applicants should have recently completed, or be close to completion of a PhD studies in electronics or physics. Preference will be given to applications submitted by candidates within five years of receiving their PhD. Additional requirements The applicant shall have a good knowledge of electronics hands on experience with test setup and electrical parameter measurements. An understanding of radiation effects in semiconductors and solid state physics is advantageous. Applicants should have good analytical skills and be able to work in a multicultural environment, both independently and as part of a team. The working languages of the Agency are English and French. A good knowledge of one of these is required. Knowledge of another Member State language would be an asset. Other information For behavioural competencies expected from ESA staff in general, please refer to the ESA Competency Framework. The Agency may require applicants to undergo selection tests. The closing date for applications is 18 October 2017. In addition to your CV and your motivation letter, please add your proposal of no more than 5 pages outlining your proposed research. Candidates must also arrange for three letters of reference to be sent by email, before the deadline, to temp.htresa.int. The letters must be sent by the referees themselves. The candidates name must be mentioned in the subject of the email. If you require support with your application due to a disability, please email contact.human.resourcesesa.int.
