At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
Introduction
Are you looking for unprecedented challenges in the world’s largest and most amazing scientific instrument? Do you have experience in carrying out studies based on low-temperature physics? Then join CERN central cryogenic laboratory. Take Part!
You will join the Cryogenics Group, which is in charge of the design, construction, commissioning and operation of the cryogenic systems for CERN's accelerators and detectors, of the operation, maintenance and upgrade of cryogenic test facilities, as well as of the management of the industrial support contract for maintenance and operation of cryogenic systems. It also provides support for low-temperature developments and experiments at the Central Cryogenic Laboratory as well as consultancy and support in cryogenic design and cryogenic instrumentation.
Within this group, the Cryolab (CL) section is responsible for the CERN central cryogenic laboratory. This lab is a research facility for systems working in a temperature range down to 50 mK, equipped with about ten test stands. The research program is based on demands specified by the CERN community and is varying from short duration experiments (several days) up to subjects covered by complete PhD programs. The diversity of people working in the laboratory, from CERN employees to students, makes it a lively environment and an attractive place to work.
Functions
As an engineer in thermodynamics or applied physicist in the Cryolab section, you will be working on the design, fabrication, installation, and operation of cryogenic test stations for the CERN Quantum Technology Initiative. In a first instance a test station shall be constructed to run a RF cavity for Axion searches at temperatures down to about 800 mK, while in the second half of the contract period a test station shall be designed and constructed to be used in the development of Transition Edge Sensors operational down to the 100’s mK region.
The design and fabrication of these laboratory test stands shall be done in collaboration with the future users of these test stations, with Cryolab colleagues and with external experts and shall be based on thermodynamic calculations and simulations. The guiding of technical students, PhD students or fellows participating to your studies, will be part of your responsibility.
Your functions will include:
Collect the theoretical and experimental requirements to be translated in project and research activitiesConceive the low temperature tests stations in collaboration with their future users and design, build and commission the low-temperature test stations accordinglyOperate the test stations and analyze the low-temperature data to continuously improve the thermodynamic conditions for the experiments mounted on these stationsGuide, advice and teach the graduates working on the project on their cryogenic/thermodynamic topics and more globally support the Cryolab colleagues in your role as expertEnsure interfacing and reporting to various stakeholders from within the Quantum Technology Initiative and beyond if necessaryRepresent the Organization at conferences, workshops, or in other research laboratories and institutionsMaster's degree or PhD or equivalent relevant experience in the field of applied physics, thermodynamics, mechanical engineering or a related field.
