Provide Description

The analysis performed on the Division of Physics and Astronomy encompasses a variety of physics matters, distributed over 9 divisions. The division is positioned within the Ångström laboratory and employs practically 400 folks, 100 of whom are doctoral college students. It gives a broad physics curriculum to undergraduate and graduate college students, participation in nationally and internationally main tasks for researchers, and alternatives for partnership with business and varied outreach actions.

Uppsala College hereby declares a PhD pupil place, on the Division of Physics and Astronomy, to be open for utility. The PhD-studies will concentrate on the investigation of the potential danger of radionuclides, particular to the European Spallation Supply (ESS), coming into the meals chain via crops generally cultivated within the farmlands surrounding the ESS website. 

In regards to the mission
Detailed research will likely be undertaken to evaluate the potential radioactive releases from the ESS, a big neutron analysis facility underneath development in Lund, Sweden. The ESS will produce neutrons utilizing a robust particle accelerator, impinging 2 GeV protons on a tungsten goal. The nuclear reactions can even produce many radioactive by-products, similar to isotopes of W, Hf, Ta, Gd and Lu. These radionuclides could also be launched within the setting after a extreme accident, and be transferred from soil to crops cultivated within the native farmlands, with doubtlessly dangerous well being results.

The mission will likely be collectively performed by the Ion-physics group at Uppsala College (Sweden), Medical Radiation Physics Malmö at Lund College (Sweden), the Biotechnical College on the College of Ljubljana (Slovenia), and the Division of Low and Medium Power Physics on the Jožef Stefan Institute (Slovenia). The profitable applicant will likely be primarily based on the College of Uppsala, however is predicted to spend time in any respect establishments concerned within the mission. The Ion-physics Group at Uppsala College employs beams of swift ions to review their interplay with supplies in stable and gaseous varieties at an atomic and molecular stage. These strategies allow the dedication of concentrations and depth profiles of atoms and molecules in a cloth with very excessive accuracy for samples from organic, environmental and technological contexts. A 5 MV tandem accelerator, a 350 kV excessive present ion implanter and a Low-Power Ion Scattering System type the experimental platform. The Environmental Radiology group at Medical Radiation Physics Malmö (Lund College) has in depth expertise within the monitoring of radioactivity within the setting through in-situ and laboratory measurements but in addition via modelling and simulations. The group’s infrastructures embody laboratories for the chemical preparation and the evaluation of environmental samples by radiometric strategies. The group additionally has ongoing collaboration on environmental monitoring with the ESS and hyperlinks to the Lund College analysis infrastructures (AMS, ICP-MS…). This group can even present modelling of the radiation doses incurred by the consumption of crops contaminated by chance launch from ESS. The Biotechnical College of the College of Ljubljana, the most important Slovenian College, is a public training and analysis organisation with 9 separate departments, collectively masking quite a few life sciences disciplines. Plant development facility and pattern preparation tools and experience required for the execution of the mission can be found on the Division of Agronomy and the Division of Biology, respectively, the place all plant materials will likely be processed and ready for additional analyses. The Division of Low and Medium Power Physics on the Jožef Stefan Institute, the main Slovenian scientific analysis institute, manages the Microanalytical Centre the place analysis with accelerated ion beams is performed. Amongst ion beam evaluation strategies accessible, micro-particle induced X-ray emission (micro-PIXE) end-station is routinely used to find out distribution of components in organic tissues in a quantitative method at micrometre decision.  As well as, a table-top micro-XRF is obtainable for bigger scan areas when poorer decision (>15 micrometre) suffices. Each equipment will likely be used for the detection of components and their allocation in plant tissues.

Work duties
The mission crosses the fields of physics, chemistry and biology in a extremely multidisciplinary and collaborative effort, combining sampling within the subject, experimental work within the laboratory and modelling.

• Experiments will likely be performed to find out the migration price of W, Hf, Ta, Gd and Lu via the soil column after floor deposition of those metals.
• Experiments will likely be performed to review the switch of W, Hf, Ta, Gd and Lu, from the soil to the plant species which can be generally cultivated within the native farmlands.
• Environmental fashions will likely be developed to foretell the dispersion of the EES-related W, Hf, Ta, Gd and Lu radioisotopes in case of unintentional releases.
• Estimates of the dose acquired from meals consumption by an uncovered inhabitants will likely be obtained for various accident eventualities.

Crops frequent to Southern Sweden (wheat, barley, rapeseed and sugarbeet), will likely be cultivated in contaminated soil close to to the ESS website and harvested for evaluation. Soil will likely be periodically collected from the contaminated website and analysed, to determine the migration of the contamination. The identical crops can even be cultivated in a laboratory setting in Slovenia and harvested for evaluation. The experimental knowledge will likely be obtained utilizing steady isotopes of W, Hf, Ta, Gd and Lu. Measurements on elemental concentrations in soil and plant samples will likely be carried out by quite a lot of strategies, together with nuclear-microprobe evaluation, X-ray fluorescence, synchrotron radiation nano-X-ray fluorescence, scanning electron microscopy and inductively-coupled plasma mass spectrometry. The modelling work will likely be carried out utilizing the software program Ecolego, that has already been used for the commissioning of nuclear installations in Sweden, together with the ESS.

Necessities
To fulfill the entry necessities for doctoral research, you have to

• maintain a Grasp’s (second-cycle) diploma in pure science self-discipline, or
• have accomplished not less than 240 credit in increased training, with not less than 60 credit at Grasp’s stage together with an unbiased mission value not less than 15 credit, or
• have acquired considerably equal data in another means.
• be capable of display wonderful communication expertise;

have wonderful research deserves; exhibit wonderful expertise in each oral and written English; have the ability and keen to journey, each nationally and internationally, regularly.

As a result of emphasis on knowledge assortment via each field- and laboratory-work, sensible expertise will likely be attributed the best precedence.

Fascinating / in any other case meritorious

• a background in both a Physics or an Environmental Science self-discipline;
• a robust curiosity in interdisciplinary analysis;
• sturdy knowledge evaluation expertise;
• previous experiences in modelling;

Guidelines governing PhD college students are set out within the Increased Training Ordinance chapter 5, §§ 1-7 and in Uppsala College’s guidelines and pointers .

In regards to the employment
The employment is a short lived place in line with the Increased Training Ordinance chapter 5 § 7. Scope of employment 100 %. Beginning date 8 January 2024 or as agreed. Placement: Uppsala
