Postdoctoral Research Assistant in Astronomical Instrumentation and Optical Design for Extra-Solar Planet Characterisation

Postdoctoral Research Assistant in Astronomical Instrumentation and Optical Design for Extra-Solar Planet Characterisation

University of Oxford - Department of Physics

Oxford, United Kingdom

Vacancy reference: 143602

The successful candidate will setup a laboratory experiment to quantify and determine the limitations on the contrast ratio achievable with both types of integral field spectrographs. The majority of the spectrograph optics is already available and partly pre-aligned, and the lensletarray and image-slicer integral field units require finalising their opt-mechanical design. It will be your responsibility to construct and align the remaining spectrograph optics, and setup the experiment including light sources, camera, and control software. In addition, you will conduct the measurements, and analyse the acquired data.

Following the completion of the current R&D phase of ELT-PCS, the project will have kick-off and start its design and build phase. Depending on the technological readiness level of other PCS sub-systems this could be as early as 2020/21. During the preliminary and final design phases of PCS you will play a leading role in the optical design of the integral-field spectrograph, analysing and documenting its performance for review within the PCS consortium and for ESO.

Additionally, the role could include supporting or taking a leading role in the optical design of other instruments being developed in the sub-department.

Responsibilities

During the ELT-PCS R&D and subsequent preliminary design phases

  • Play a leading role in the optical design of the spectrograph and integral field units, and engage actively in the mechanical design with the PI and mechanical design engineer;
  • Oversee the procurement and manufacturing of its components;
  • Assemble, integrate, align, test, and characterise the spectrograph and its components.;
  • Measure the maximum achievable contrast of the two types of integral field spectrographs;
  • Document research activity through technical reports and journal articles;
  • Contribute to the design and analysis of other instrumentation projects within the group;
  • Participate in group meetings and seminars within the department;
  • The post-holder will have the opportunity to teach. This may include lecturing, small group teaching, and tutoring of undergraduates and graduate students.

Hazard-specific/Safety-critical duties

This job includes use of an imaging interferometer for the wavefront error characterisation of the optical components and systems. The interferometer is operating using a Laser at a wavelength of 1064nm, which is classified as 3b. This poses the following hazards or safety-critical activities which will require successful pre-employment health screening through our Occupational Health Service before the successful candidate will be allowed to start work:

  • Working with category 3b lasers (laser safety class).

Selection criteria

The successful candidate will be chosen from amongst the applicants based on the fulfilment of the following criteria:

Essential

  • Doctoral degree in Astronomy, Physics, Engineering or related field;
  • Proven record of academic research including experimental work;
  • Writing skills (technical reports/research papers/instrument manuals/review documents);
  • Experience in at least one of: (1) optical design; (2) mechanical design; (3) assembly; (4) integration; (5) testing of a relevant astronomical instrumentation project, either at predoctoral or post-doctoral level;
  • Demonstrated abilities of data analysis/scientific computing.

Desirable

  • Decision-making, problem-solving, planning, and organising skills;
  • Experience with designing/building/analysing data from an integral field spectrograph at visible/near-IR wavelengths;
  • Experience with high-contrast observations, in particular the field of “Direct Imaging”, and their data analysis, in particular the field of “Speckle Suppression”;
  • Advanced experience in optical design and optical design software, e.g. ZEMAX, and familiarity with mechanical design software, e.g. Autodesk Inventor.
