Wie is Arjan?
Arjan Boerma is vijfdejaars student technische natuurkunde en oud-secretaris van Francken. Dit jaar is hij student-lid van het opleidingsbestuur en geeft hij ons eens in de maand een kijkje in de keuken van de School of Science and Technology.
Ik heb het dit jaar al vaak gehad over de onvermijdelijke verandering van de onderwijsstructuur: de fusie van de ‘verticale’ opleidingsinstituten en daaropvolgende splitsing in ‘horizontale’ Graduate en Undergraduate Schools (GS en UGS).1 Per 1 september moet die structuur operationeel worden, maar een heleboel zaken zullen pas in de loop van het volgende collegejaar hun definitieve vorm krijgen – waaronder dingen die jou als student direct aangaan. Reden te meer om je hier mee te willen bemoeien!
Voor volgend collegejaar is de Bètastuf op zoek naar twee studenten die in het bestuur van de UGS (voor de bacheloropleidingen), en een student en een promovendus die in het bestuur van de GS (voor de masteropleidingen en PhD-trajecten) willen plaatsnemen. Ik kan het iedereen aanraden, want lidmaatschap van het OB is een ontzettend leerzame functie die prima met je studie te combineren valt.2
Als je meer info wil, kan je mij natuurlijk mailen. Direct solliciteren kan natuurlijk ook.
Applications Scientist

in Vacature
Applications Scientist (Diplom/Masters or PhD in sciences or engineering), f/m. Mannheim, Germany
Atomic Force F&E GmbH, the European distributor for Asylum Research, the technology leader in scanning probe/atomic force microscopy, is seeking an Applications Scientist to assist current and potential customers using AFMs in many diverse applications - from biology to semiconductors. The position will be based in Mannheim, Germany and will require frequent travel throughout Europe.
Job Responsibilities
Responsibilities include performing product demonstrations, running samples, and training/supporting customers on Asylum Research microscopes in the field and at the Mannheim office. The Applications Scientist will be responsible for applications and customer support on instrumentation and accessories. The position also requires scientific presentations at conferences, workshops and customer demonstrations. The candidate will also assist with new product development and applications as dictated by customer requirements.
Requirements
The successful candidate will have a solid academic background (PhD preferred) and will have a minimum of five years practical and theoretical AFM experience, preferably encompassing work in the fields of physics, materials, and/or life sciences. The candidate must be a fast, self-learner and have excellent communications skills, both written and oral, and must be able to understand customer needs, gain customer feedback and develop a strong understanding of competitive technology and products. Asylum Research microscope experience and IGOR Pro programming a plus. Fluent German and English oral/written skills are required.
About Us
Atomic Force F&E GmbH is a distribution company offering an informal work environment in a young and multinational team of AFM experts. The candidate will have the opportunity to work with the most talented scientists and engineers in the field of AFM with the potential to create a unique position in the company. Our office language is German, but fluent English communication is needed with many customers and suppliers. Due to frequent travel in Germany and Europe, a company car will be provided that can also be used privately.
Apply for the Job
Further information about the open position can be obtained from Roland Goschke (goschke@AtomicForce.de) or Stefan Vinzelberg (vinzelberg@AtomicForce.de. To apply for the position, please send your resume in a PDF file to jobs@AtomicForce.de and indicate the job position in the subject line. Please note that all Word docs will be rejected. Please also include a cover letter and salary expectations. Atomic Force F&E GmbH is an equal-opportunity employer.
Proton radiography: an imaging tool for medical applications
08-05-2012
in Onderzoek
Proton radiotherapy allows to reduce the radiation dose to the healthy tissues that are inevitably also irradiated during radiotherapy. Therefore proton radiotherapy should lead to a better treatment outcome (higher cure probability, less and/or less severe complications) than the conventional radiotherapy with photons for a significant fraction of the cancer patients treated with radiotherapy. The planning of a proton radiotherapy treatment is, however, significantly more complex than that of a conventional radiotherapy treatment. Also, the quality of the treatment plan is much more sensitive to the quality of the information on the properties of the tissues that the protons traverse on their way to the tumor. This information is mainly obtained from X-ray CT imaging and has to be interpreted using a model because the interaction of X-rays with tissue is different from that of protons.
In the framework of the research programme on proton radiotherapy that is associated with the planned clinical facility for proton radiotherapy at the UMCG campus, KVI has in collaboration with Nikhef and INCAS3 started a study on imaging with protons instead of X-rays to improve the quality of the information for the planning of proton radiotherapy treatments.
We will develop a proof of principle detector system that will be used to assess the capabilities of proton radiography imaging to provide better quality information than X-ray CT imaging. This detector system consists of two tracking detectors that measure the 3D-trajectory of individual protons before and after their passage through the patient’s body and a so-called calorimeter that measures the remaining energy of the protons.
For the design of the detector system and the development of the data analysis algorithm, extensive simulations of the detection of the protons and their interaction in the patient’s body are needed. The reconstruction of a 2D-map of the average tissue density from the measurements is relatively straightforward. However, it is also possible to obtain depth information using more sophisticated ray-tracing techniques, a kind of “software microscope” that can be focussed at different depths in the sample.
We are looking for an MSc-student in physics with an interest in computational physics and medical applications of physics to do her/his MSc-thesis research in this project. She/he will contribute to the design of the detector system, the development of the data analysis and the study of the optimum measurement conditions. The work will mainly consist of large scale simulations using GEANT4. In addition she/he will participate in prototype tests and their analysis.
