Jack Harris, Associate Professor of Physics
Professor Harris studies the quantum aspects of motion in mechanical, optical, and electronic systems. His experiments use ultrasensitive force detectors to measure the ground state properties of electrical circuits, the quantum back-action of displacement measurements, and eventually the quantum properties of the mechanical force sensors themselves.
JPE has provided us with two valuable services. The first is their Piezoknob motor, which has greatly improved the stability, rigidity, and reliability of our cryogenic translation stages. Our experiment uses nine of these motors, and they have all worked on multiple cooldowns. The second service is JPE’s input on the mechanical design of our experiment. They improved the design of our flexure mounts and of the overall assembly of the cryogenic stage, leading to a more robust experiment. Interacting with them has been very easy and productive.

Dr. Francisco Garzón López, Researcher
Principal Investigator EMIR Consortium at the Instituto Astrofísica de Canarias (Tenerife, Spain)
Professor at the Astrophysics department of the University La Laguna (Tenerife, Spain)
JPE developed an extremely complex cryogenic robotic mask unit to be installed in a last generation astronomical instrument for a 10m class telescope. This system has over one hundred cryogenic linear moving parts with positioning accuracies of a few microns to be attained in an environment at around -200ºC.
The unit is now complete and fully functional. Throughout the different phases of the project, we have worked increasingly closely with the staff of JPE and can attest to their dedication and professional ability. We have been very happy with the choice of JPE as the main contractor for the project.
Dr. Bernhard Brandl, Professor of Infrared Astronomy, Principle Investigator of METIS, an astronomical instrument on the E-ELT.
Bernhard’s scientific interests are:
For the METIS instrument on the future 39m European Extremely Large Telescope (E-ELT), JPE has been developing a challenging optical beam chopping mirror for NOVA (Dutch university astronomy departments). Not only has the mirror to move extremely fast and accurate in all directions, but it has to operate at -200 degrees Celsius and perform more than a hundred million cycles. In order to reach its very tight performance requirements, the compact design had to accommodate interferometric sensors. JPE took care of the design, construction, testing, and documentation. Throughout the development, the interaction was pleasant, constructive and efficient, and we will certainly consider JPE for future projects.
HVE develops and produces particle accelerator systems for scientific and industrial applications. Faced with a complex and relatively new project with a challenging deadline, JPE was contracted for the design of an end-station for industrial wafer implantation. The people at JPE quickly understood the specific requirements for our machines and came up with the right concept from the start. All specifications were realized, and the project was successfully completed.
Our working relationship has been pleasant and very constructive. JPE’s practical approach and technical know-how are much appreciated at HVE.
Movement of a sample during a neutron scattering experiment at low temperatures and very high magnetic fields is an unusual and difficult task. High mechanical precision is needed and the measurement should not be perturbed by heat input for example during movement. The development of this tool was possible in collaboration with JPE because they were able to work very closely together with our team and understand all our requirements in detail. So we did not only profit of JPE’s products and JPE’s expertise in general, we received a specially adapted design for our very special experimental situation. The collaboration was always constructive and therefore perfectly efficient

JPE offers interesting technical challenges. At JPE, you participate in a multidisciplinary development team and work on different projects. Due to the intensive cooperation with the project team, the company provides a perfect environment to expand our and your technical knowledge and experience to a higher level.
We are looking for new colleagues who share our passion for the development of systems for high precision applications. We work in small and dedicated project teams which requires a broad skill set to be effective, as the field of work ranges from creating architecture concepts for new systems down to tackling integration issues when building a cutting edge, first-of-a-kind system.
Candidates should preferably have an academic degree in mechanical engineering. Both excellent communication skills as well as multidisciplinary and creative thinking are demanded to be an effective member of our development team.
Experience in the high-tech industry of scientific instrument development is a strong pro, but not an essential constraint. Being a leading center of expertise in precision engineering, and having a open and flat organisation structure with plenty of room to improve your personal and technical skills that are needed for the development of high-tech systems.
We are looking forward to get in contact with interested candidates. Please go to our website and reply via the standard contact form. We strongly prefer to get in direct contact with potential applicants and we discourage recruitment consultants or other intermediaries to contact us.
