Job description
A PhD position is available at LT in a new project sponsored by the Dutch technology foundation STW. In this new project we want to develop multi-stage microcoolers that are able to reach even lower temperatures (~30K), and small sorption compressors [2] that can replace the pressurized gas bottles, and thus realize closed-cycle microcooling systems. The PhD should focus on the thermodynamics and design of multi-stage coolers, on the mechanism of clogging caused by water deposition, and measures to prevent this to occur [3], and on the development of a full package design
(including vacuum). In parallel, a post-doc researcher will be appointed in the project focusing on the utilization of results in two demonstrator pilots. In these pilots, LNAs will be cooled with a number of cooler tips fed by a single sorption compressor.

Job type: Research / Advising
Workfield(s) :
- Research trainees, non-tenured lecturers, researchers( Scientific discipline: Engineering)
Organization
University of Twente
Low-Temperature division
The Faculty of Science and Technology (700 faculty members, 1100 students) offers a range of bachelor and master courses (NanoTechnology, Applied Physics, Chemical Engineering and Technical Medicine). The faculty's research is organized in three of the university's interdisciplinary research institutes: MESA , BMTI, and IMPACT. These institutes increase the vitality of research by enabling collaboration between programs and disciplines, by providing shared facilities, and by attracting funding for joint projects. They also provide a conduit to industrial partners and help
in attracting new faculty.
In the Low-Temperature division (LT) of the University of Twente (UT) cryogenic cooling based on MEMS technology has been investigated for about a decade. In this research, we aim to realize extremely small coolers by means of micromachining technologies (MEMS) for reaching cryogenic temperatures, well below 120 K, i.e. 150 oC. There is a growing need for these microcoolers for cooling advanced electronics, such as low-noise amplifiers (LNAs), detectors, superconducting circuits, etc. In a previous project [1], we developed a miniature 100 K cooler in which gas is expanded that is supplied by a high-pressure gas bottle (see figure).
Conditions of employment
Estimated maximum salary per month: eur 2000 - 2500
Maximum salary amount in Euro's a month 2502
Employment basis: Temporary for specified period
Duration of the contract: 4 year
Maximum hours per week: 38
Additional conditions of employment:
We offer an interesting temporary research position . You will be appointed for a period of four year, with an assessment within one year. A positive assessment will secure the continuation of the appointment for another three years. The salary starts at €1.956,- gross per month increasing to € 2502.- gross per month in the fourth year.
PhD students are expected to complete their research with a thesis. Benefits and other conditions of employment are in accordance with the Collective Labour Agreement for Dutch Universities.
