R&D support employee – beamline operator

HollandPTC is looking for a beamline operator to assist with experiments on the R&D proton beamline. A unique opportunity to gain work experience in proton research!

The research team at HollandPTC conducts and supports preclinical research, ranging from radiobiology and physics experiments to radiation hardness testing of electronics for the aerospace industry. These tests are performed for both academic research groups and commercial clients, who test electronics for satellite communication and other applications. The focus is on studying Single-Event Effects (SEEs) as well as cumulative dose effects.

Do you have an affinity for precision, technology, and customer-oriented work? Do you enjoy contributing to the smooth and professional execution of measurement evenings for international clients? Then we would like to meet you.

Your role

As a beamline operator, you will support researchers and clients during beamline experiments, mainly for radiation hardness testing. Your tasks and responsibilities include:

• Setting up, modifying, and dismantling standardized experimental setups
• Discussing, monitoring and adapting the measurement plan for the evening
• Performing irradiations alone together with the researchers or clients
• Supervising radiation safety during experiments
• Actively communicating throughout the experiment (English is the working language)
• Flexibly adapting to changes in the measurement plan
• Solving technical or practical issues, also under time pressure

Experiments are mainly conducted in the evening. Working hours are typically between 6 pm and midnight. Irradiation blocks last approximately 4 hours, excluding setup and dismantling time. The schedule is determined shortly in advance, which is why this position requires flexibility.

Training will be provided by shadowing an experienced beamline operator during multiple experiments. Once you are sufficiently trained, you will gradually start conducting experiments independently.

For students with an affinity and interest in proton research, this is a unique opportunity to gain work experience. This position can also be easily combined with a study.

About HollandPTC

HollandPTC is an independent outpatient center for proton therapy, located in Delft. With a team of over 100 colleagues, we work in healthcare, physics, research & development, and operations. We collaborate closely with physicians, physicists, and researchers from other organizations to deliver patient care and innovative research. One of the research facilities is the ‘R&D beamline’, consisting of an R&D bunker with a fixed horizontal proton beamline and labs for preparing physics, technical and biological experiments.

About the department

You will work within the research & education department and closely collaborate with R&E staff.

Education and profile

We are looking for a candidate who matches (part of) the following profile:

• bachelor (minimal third year) or master student in Applied Physics or bachelor (minimal third year) or master student in Aerospace Engineering
• affinity with experimental research and technology
• accurate, responsible, and communicative
• fluent in English (English is the working language)

A radiation protection officer D (TMS-D) certificate is a plus. If you do not yet have this certificate, you must be willing to obtain it in the short term

What we offer

In addition to a challenging and educational position, we offer:

• a one-year contract (flexible contract), with possible extension
