I studied Physics Engineering at Politecnico di Milano (Milano, Italy), where I earned a bachelor’s degree followed by a master’s degree. Both of them consisted mainly of solid state physics classes, with a particular focus on semiconductors (for electronics and photonics application) and magnetic nanostructures. My first experience in research was at the European Synchrotron Radiation Facility (Grenoble, France), where I spent 10 months working as a trainee for my master thesis project.

Applications are invited for a 4-year PhD studentship, based jointly at the University of Oxford and Diamond Light Source Ltd.
This PhD research project aims to develop the next generation of X-ray optical components for obtaining nanometre scale X-ray focal spots.
The Diamond Light Source provides intense beams of X-rays delivered along beamlines to about 30 diverse experiments. Specialised X-ray optical components are used to focus the X-rays into sub micrometre focal spots in order to obtain high photon flux density and high spatial resolution at the sample. Currently the smallest X-ray spots achievable at Diamond are sub 100 nanometre.
Achieving such small focused X-ray beams places great demands on the quality of the X-ray focusing optics for example reflective optics (X-ray mirrors) should have figure errors below 1 nanometre. The imperfection in the optics become visible at the focal plane where the spot size is increased and the imperfections can also be measured in-situ using sensitive techniques (at wavelength X-ray metrology). In a recent break through [Sawhney, Laundy et al, Appl. Phys. Lett.(2016), http://dx.doi.org/10.1063/1.4960593], the Optics Group at Diamond showed that by making accurate measurements of the distortion imposed by an X-ray mirror, it was possible to design a refractive X-ray optical component that could be used to cancel out the distortion. This technique has the potential to obtain X-ray focal spots sizes of less than 10 nanometre in size which would be of great benefit to the cutting edge experiments performed at the synchrotron.
The successful applicant will participate in the design and microfabrication of the novel X-ray optics; evaluation of the optics, in particular performing sensitive measurements to characterise the new optics on the B16 Test Beamline at Diamond.
Start date: October 2017
Entry requirements and Funding:
Applicants should have or expect to obtain a first class honours degree (or equivalent) in Physics, Engineering or a related subject with a strong interest in doing experimental research using complex tools.
Prospective candidates will be judged according to how well they meet the following criteria:
The following skills are desirable but not essential:
The studentship is open to UK, EU and international students but the University fees are covered only at the UK/EU rate. Therefore overseas students would have to provide the difference between the UK/EU and the overseas student rates for University fees from some other source, such as a scholarship or personal funds. This studentship includes a stipend (tax-free maintenance grant) of £16,300 p.a. for the first year, and at least this amount for a further two years. The studentship does cover the payment of college fees (c. £3021 p.a.).
How to Apply:
Applications should be made directly to University of Oxford, details here.
Informal enquiries are encouraged and should be addressed to Professor Alexander Korsunsky (firstname.lastname@example.org).
To apply formally for this studentship, candidates should send the following documents to email@example.com:
Candidates must also submit a graduate application form and are expected to meet the graduate admissions criteria. Details are available on the course page of the University website at www.ox.ac.uk/admissions/graduate/courses/mpls/engineering-science.
Please quote NOXSB_AK_2017 in all correspondence to the Department and in your graduate application.
Application deadline: Friday 28th July, 2017, Interviews will be held in mid-August, 2017.
