The studentship is part of a funded project on refractive optics for X-ray wavefront correction being jointly undertaken by the University of Oxford (A.M. Korsunsky) and Diamond Light Source (K. Sawhney and D. Laundy).
Diamond Light Source (http://www.diamond.ac.uk) is the UK’s national synchrotron science facility. The facility provides intense beams of X-rays delivered along beamlines to diverse experiments. Specialised X-ray optical components are used to focus the X-rays into sub-micrometre focal spots 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. The Optics Group at Diamond are developing micro-fabricated refractive optical components to correct for the fabrication errors in X-ray focusing optical components with the potential to obtain X-ray focal spots sizes of less than 10 nanometre in size. This would be of great benefit to the cutting edge experiments performed at the synchrotron.
The successful applicant will participate in the design and fabrication of this novel X-ray optics; evaluation of the optics, in particular performing sensitive measurements to characterise the new optics on B16, the Test Beamline. At Oxford, the student will become a member of Prof. Korsunsky’s group (MBLEM).
Applications should be made directly to University of Oxford, details here.
Informal enquiries are encouraged and should be addressed to Professor Alexander Korsunsky (email@example.com).
To apply formally for this studentship, candidates should send the following documents to firstname.lastname@example.org:
- Covering letter (explaining your suitability for the study, what you hope to achieve from the DPhil and your research experience to date)
- Contact details for two academic or professional referees
Start in October 2017.
Application deadline: Friday 28th July, 2017, Interviews will be held in mid-August, 2017.

Subject: OkMC simulations of dislocation loop evolution in presence of dislocation lines in Fe/FeCr under irradiation.
The objective of this PhD is to simulate the evolution of defects in structural materials (stainless steels) such as Fe/FeCr under neutron and ion irradiation in order to evaluate the number and types of defects that interact with dislocation lines, which can lead to hardening of the material. Simulations will be mainly performed with the recently developed (at CIEMAT) code Object kinetic Monte Carlo based on GPU programming. This work will be carried out in the framework of the European H2020 project M4F (Multiscale modeling for fusion and fission materials), that will start in September 2017.
Required skills: Good background in C++ programming. Knowledge of CUDA programming will be highly appreciated. And a strong motivation!
If you are interested, please contact Dr. Christophe Ortiz (email@example.com).

The work will be focused on microstructural characterization and nanotribology experiments applying advanced micromechanical experiments (wear experiments, in-situ micro-mechanical testing) and characterization methods (scanning electron microscopy, focused ion beam microscopy and atom force microscopy).
Applications exclusively via email to firstname.lastname@example.org .
Please include a letter of motivation, a CV, if existing, a list of publications and up to two letters of recommendation. Applications will be accepted until a candidate is found.

PhD and Post-Doctoral positions in Nanomechanics (Atomistic simulations) at the Technion, Haifa, Israël.
The Nanomechanics Simulations Laboratory at the Technion (Israel) is seeking applicants for a computational study on nucleation controlled plasticity. Two immediate openings are available for doctoral and postdoctoral research associates.
The positions are available in two projects.
-One project focuses on developing nucleation criteria at the nanoscale at various geometries and conditions.
-The second project, which is within the framework of collaboration with an experimental German group, aims at understanding the importance of an existing microstructure on nucleation controlled plasticity.
-The postdoctoral position is offered for a period of two years with a possible extension for an additional year.
At the doctoral level, prior knowledge in atomistic simulations / dislocation dynamics simulations and in theory of dislocations is desirable (but not obligatory). At the postdoctoral level, a similar background is essential.
For further information or to apply, please contact Prof. Dan Mordehai at danmord[at]tx.technion.ac.il

The objective of this work will be to participate to the integration of copper filled TSV in Siphotonics platform and to investigate the effect of TSV induced strain on optical components such as wave-guides, photo-diodes, and modulators. The quantification of the stresses in photonic Si is vital for the optimization of design and for the development of reliable 3D stacked structures.
ThePhD student task will be to define and integrate 3D test structures including TSV-Middle and optical elements in collaboration with Si-Photonics design team. Advanced characterizations (μ-Raman, nano-diffraction at synchrotron) will be carried out to extract strain maps in optical components around TSV.
Partners: ST Microelectronics Crolles, CEA Leti, IM2NP (Aix Marseille Univ & CNRS).
For further information, please contact:
Olivier Thomas (Olivier.Thomas@im2np.fr) or Stéphanie Escoubas (Stephanie.email@example.com)
Applications including a CV and a motivation letter should be sent to Olivier.Thomas@im2np.fr.
Deadline: June 20th, 2017.
