Mechanical Engineer or Physicist for Vacuum Engineering at Elettra 2.0

Website elettrasincro Elettra Sincrotrone Trieste

Deadline: 31 May 2022
Ref: RA/22/9

Company description

Elettra Sincrotrone Trieste is an international multidisciplinary research center operated as a user facility, featuring a 2.0/2.4 GeV, third-generation synchrotron light source (Elettra), a new free-electron laser light source (FERMI) and a variety of support laboratories. The extremely high quality of the machines and beamlines has set new performance records and has been producing results of great scientific and technological interest. A new generation, diffraction-limited storage ring light source denoted as Elettra 2.0 is under development. See for more information. In order to allow the laboratory to remain competitive in the next 20 years, an entirely new source – Elettra 2.0 – belonging to the new generation of storage rings (DLSR or Diffraction Limited Storage Ring) is being developed. The new source will exhibit a major increase in the brilliance and coherence fraction of the photon beams. The Elettra 2.0 optics is based on our enhanced symmetric six bend achromat structure (S6BA-E) with a 12-fold symmetry and an emittance of 200 pm-rad at 2.4 GeV. The new structure creates also straight sections in the arcs permitting the installation of additional insertion devices, thus increasing the number of beamlines. Existing beamlines will have to be upgraded and new beamlines developed to take full advantage of the characteristics of Elettra 2.0. In addition, three in-vacuum undulators and two high-field superbends are going to be installed. The new machine is scheduled for commissioning in the second half of 2026.

Beamline / Project / Activity description

The vacuum engineering team is mainly dedicated to the development and maintenance of the large vacuum systems necessary for the Elettra and FERMI machines to function. They also advise and support scientists and technicians in their day-to-day beamline and laboratory vacuum needs.

Job description

The successful candidate will be part of the vacuum engineering team involved in designing  and testing vacuum systems and components dedicated to the front-ends of the Elettra 2.0 storage ring and beamlines. The successful candidate may also be involved, with the other members of the team, in the maintenance activities of the vacuum systems and components of the current machine to free other members of the team to increase their involvement in the developments related to the new machine.

The candidate will:

  • contribute to the definition of all vacuum requirements (e.g., material properties, cleaning procedures, instrumentation) for the development of the vacuum systems and special vacuum components of the front-ends and beamlines;
  • contribute to the design of the vacuum system and perform vacuum simulations to assess vacuum system performance;
  • define the vacuum interlock system rules and write the related documentation;
  • discuss and propose the mechanical integration of vacuum components, vacuum instrumentation and ancillary systems in the general layout of Elettra 2.0;
  • produce the technical documentation required for procurement and follow the manufacturing and construction stages of all vacuum components;
  • perform vacuum test on prototypes and final components at the vacuum laboratory, analysing data and issuing test reports;
  • review technical reports issued by contractors and participate in the factory acceptance tests;
  • collaborate to on-site installations and commissioning of front-ends and beamlines.

A Master Degree in Mechanical Engineering or Physics is required together with experience in writing and reviewing technical documentation and performing data analyisis to produce test reports.

Experience in the assembly of scientific apparatus or in the installation of large mechanical systems, along with experience in 3D mechanical design using CAD programs would be considered an asset. Experience in vacuum science and technology, as well as knowledge of Molflow+ and Synrad programs or other vacuum simulation softwares would be highly desiderable.

Good knowledge of Microsoft Office or similar software suites is required.

Good oral and written communication skills in Italian and English are essential.

Good time management skills and ability to prioritize are expected, together with the capacity to interact with staff and to work as part of a multi-disciplinary team.
