The main focus of the Institute for SRF – Science and Technology (FG-ISRF) at the HZB is the development of new accelerator systems based on CW superconducting radiofrequency techno¬logies. Currently we are building just now together with the Institute of Accelerator Physics two new SRF-based accelerators at the HZB: bERLinPro and BESSY VSR. We are also conducting an intensive basic research program to better understand the RF power of niobium and other new superconductors suitable for SRF cavities.

•    Organization of testing campaigns for superconducting cavity systems in cryogenic test stands and cryomodule commisioning
•    Coordination of an interdisciplinary group to arrange SRF tests (cryogenics, mechanical engineering, electrical engineering, radiation protection, vacuum systems)
•    Participate in clean room preparation work
•    Write reports and scientific documentation

•    University degree in Physics or Engineering (electrical engineering, mechanical engineering or related field)
•    Hands on experience in testing of accelerator cavities
•    Basic experience in the operation of cryo-cooled components
•    Clean room experience is desired
•    Self initiative and ability to perform work independently
•    Interdisciplinary communication skills
•    Good written and oral English

Post title Mechanical Design Engineer- Cryogenic Systems
Grade 8: £41,526 – £49,553 per annum
Fixed term for 3 years
Applications are invited for the post of Mechanical Design Engineer in the Engineers group which provides design support for Physics research.
The post is available initially for a fixed-term duration of three years.

The Department of Physics is seeking a talented Mechanical engineer.

The successful candidate will design, analyse and arrange for the production of components, mechanical moving parts, test rigs and experimental equipment for Physics research. A large portion of the work is in the area of precision instrumentation for experimental physics, with a focus on the design and analysis of opto-mechanical systems operating at cryogenic temperatures (typically ~100K, ~4K).

You should be able to develop a concept into something practical and take ‘ownership’ of it. 

Applicants should possess a degree in Mechanical Engineering or have equivalent experience. In the latter case, two references are required which specifically details the applicant’s professional level and explains how these are considered equivalent to the required qualification. They should have a strong background in the use of 3-D mechanical CAD design software with sound knowledge of established drawing standards and design methods and with a good understanding of the mechanical behaviour of structures.
Previous experience in a research environment will be an advantage.

Candidates are expected to demonstrate that they can manage projects from conceptual design to the manufacturing and final assembly and testing.
Please direct enquiries about the role to

Application deadline is no later than 12:00 noon, Friday 25 October 201


Cryogenic ltd looks for candidates to take up a position of a Measurement system development and support engineer. The role involves design, test and overseeing production of measurement probes for low-temperature experiments, as well as interaction with international customers and after-sales product support. A successful candidate will have completed a project in experimental physics, preferably (but not exclusively) in solid state / materials / low temperature physics. Practical skills in operating electronic measurement equipment, collecting and analysing experimental data as well as problem solving are essential. Candidates at both Masters Degree and PhD levels are welcome - we need at least a Masters Degree with an experimental project.   Competitive salary according to experience.

We are making exceptional progress with HTS magnets at the moment and are recruiting.   Our web site lists the following vacancies – and there will be more to come… 

HTS Mechanical Engineer, HTS Magnet Systems and Instrumentation Technician, Technical/Engineering Senior Buyer, HTS Power Electronics Engineer, HTS Cryogenic Engineer, HTS Measurement Engineer


Do you have experience in cryogenic systems & technology?

Have you worked with liquid helium systems?

Would you like to be part of an innovative programme working at the cutting edge of fusion, making the UK the centre of tritium research?

Here at the UK Atomic Energy Authority (UKAEA), you will be involved in supporting research into the future of sustainable energy - Fusion Energy.

You could be working at the Hydrogen-3 Advanced Technology centre (H3AT) which will provide a unique opportunity for academia, industry and partners to benefit from a world-class tritium technology centre. H3AT represents an important step in the development of tritium technology, allowing vital research and development to keep pace with the growing demand for tritium expertise both in the UK and the rest of the world.

Your role will be to lead work on one of the existing cryogenic subsystems. This will initially involve fault finding, recommissioning and process optimisation, and will be followed by providing general cryogenic advice, as well as plant-specific training, to the group.

The H3AT facility will also include new cryogenic subsystems, and effort will be required to deliver these.

In your new role you will:

  • lead the technical delivery of a plant 4‑K liquid helium subsystem, including liaison with vendors and subcontractors
  • act as the intelligent customer on behalf of UKAEA
  • supervise vendors and subcontractors as well as UKAEA staff during installation and maintenance on the subsystem
  • operate the subsystem and train other operators as the need arises
  • carry out risk assessments for cryogen interventions
  • evaluate designs of new systems
  • provide advice on upgrade parts of subsystem or projects for the installation of new equipment up to £350k

You will need:

  • a degree in a relevant subject with several years of experience of liquid helium systems
  • strong cryogenics safety track record
  • experience of plant control systems including interlocks
  • experience of pressure systems regulations
  • experience of training others in cryogenic safety and operation of cryogenic equipment


So, if this sounds like you, and you are looking for that next challenging career move, then please send your applications using the link provided.

Please note, the role is only offered on PAYE or Umbrella basis. We are unable to engage with any Limited Company contractors.

All successful applicants must undertake a BPSS clearance (basic security clearance)
