RMS Meeting: EBSD 2020


Scientifi c Organiser: Professor Bradley Wynne, University of Sheffi eld

A ground breaking technique that could produce an electron beam up to 10,000 times brighter than the most powerful beams today, has been developed by researchers from the UK and US. The fi ndings* could be particularly applicable for use in the next generation of more compact, more powerful particle accelerators, enhancing scientifi c applications.


Led by the University of Strathclyde’s Professor Bernhard Hidding, who is also a member of the STFC’s Cockcroft Institute, the E-21-: Trojan Horse experiment which was carried out at the US Department of Energy’s Stanford Linear Accelerator Center (SLAC) in California, involved releasing electrons from neutral atoms inside plasma, to produce a potentially much brighter, plasma-based electron source. Professor Hidding said:


“Our


experiment demonstrates the feasibility of one of the most promising methods for future electron sources and could push the boundaries of today’s technology by orders of magnitude.”


The researchers also developed several auxiliary techniques, which would improve the quality and stability of their output beams and to harness the technique for applications.


In a forward-looking, complementary project funded by STFC, Professor Hidding and colleagues from UK and US are already exploring the benefi ts to be expected from ultrabright and ultrashort electron beams for X-ray free electron lasers and other light sources at CLARA, a particle accelerator designed to develop, test and advance new technologies for the next generation of particle accelerators and free-electron-lasers, at STFC’s Daresbury Laboratory. In conjunction with further R&D at SLAC’s FACET-II facility, the Scottish Centre for the Application of Plasma-based Accelerators (SCAPA) and the Central Laser Facility (CLF), these ultrabright beams may eventually allow production of X-ray pulses short and bright enough to allow observation of electronic motion inside atoms and molecules on their natural timescale.

The 2020 EBSD meeting will take place at The Edge, Endcliffe Village, at the University of Sheffi eld, 21st - 22nd April. The annual meeting draws together the whole Electron Backscatter Diffraction (EBSD) community, including leading international research scientists and engineers, early career researchers and students to highlight the latest developments, from technique development through to applications.


We are anticipating contributions that range in scope spanning the geoscience, materials science & engineering and mechanical engineering disciplines, as well as emerging applications from the biological communities. Talks will likely include state-of-the- art developments in instrumentation, new software algorithms and new techniques developments, as well as the use of EBSD, transmission Kikuchi diffraction, electron channelling contrast imaging (ECCI) and related microscopy modalities. Additionally, we anticipate hearing applications driven talks which engage these approaches to reveal new insight into the microstructure of materials systems in emerging scientifi c applications and industrial challenges, particularly the use of EBSD data in Industry 4.0.


This year’s meeting will be preceded on Monday 20 April, by one of two optional workshops, for both advanced and novice users. The advanced course, delivered by Professor Joao Fonseca’s group at the University of Manchester, focusses on the use and understanding of High-Resolution Digital Image Correlation (HRDIC) combined with EBSD, centred on technical requirements and the underlying principles of post-processing data analysis.


The novice course, delivered by Professor Brad Wynne, focusses on understanding what is under the hood of your EBSD software, with particular emphasis on maximising the potential of your EBSD data both before acquiring your data and during its analysis.

RMS Summer Studentships 2020


Apply now for the RMS’s Summer Studentship scheme, as the deadline is fast approaching. Up to six studentships of £2,000 are offered every year, split evenly between physical sciences, biological sciences and interdisciplinary projects. Applications for our Summer Studentships must include a signifi cant microscopy component and should be submitted by a suitable host academic on behalf of a student. The deadline for applications will be the end of February.


The Studentship is offered on the understanding that a 500-word project report is completed by the student by the end of the period of study and submitted to the RMS. The report should be in the form of an abstract with Introduction, Materials and Methods, Results and Discussion. It should also include images/data.


Awards will be made to students at the end of their second year of study for a three-year degree, or at the end of their second or third years for four-year degree courses. Master’s students are not eligible. £1500 should be allocated by the supervisor to the student as a bursary to cover living expenses and £500 can be used to cover experimental and laboratory expenses.


The person making the application must be a Member or Fellow of the Royal Microscopical Society. To fi nd out more visit www.rms.org

Funding for


Young Researchers Attending emc2020


To support young researchers, members of the European Microscopy Society can apply for a scholarship to participate at the next EMS series: The 17th European Microscopy Congress, emc2020, taking place in Copenhagen, Denmark this August.


The application deadline is fi xed as the original conference abstract submission deadline for emc2020 (1st March 2020). Each applicant must submit at least one abstract and has to be registered at the meeting.


A copy of the abstract(s), registration details (a screen shot or printout of the confi rmation mail is accepted), and a proof of student or early stage researcher when applicable, have to be added to the application. Depending on demand, the EMS will also try to serve early career researchers, who will qualify if their PhD thesis was completed within fi ve years of the Congress start date.


Applications, including a short CV, should be submitted online via the following link: www.eurmicsoc.org/en/scholarship-form/

In-house acoustic calibration laboratory offers five day lead time as standard


To be included in our next issue, send all your News stories to:

In a move to safeguard the quality of measurements and eliminate the costs associated with unreliable monitoring equipment, AcSoft is offering traceable calibration of a wide range of noise and vibration instrumentation with a fi ve-day lead time as standard.


AcSoft’s state-of-the-art acoustic calibration laboratory


is capable of calibrating a variety of noise and vibration equipment from its subsidiaries, Svantek UK and GRAS UK, as well as instruments from other manufacturers. The laboratory calibrates sound level meters, microphones, preamplifi ers, calibrators and pistonphones, accelerometers (frequency response and sensitivity), analysers and dosimeters. The company uses the goCA calibration systems from GRAS for calibration of microphones, sound level calibrators and pistonphones.


For calibration of sound and vibration meters, AcSoft uses


a bespoke calibration system from Svantek Poland. A full factory calibration is performed on Svantek products ensuring all new instruments have a fresh calibration certifi cate every time. A bespoke shaker system from Data Physics is used for sensitivity calibration of accelerometers over a range of frequencies. A Dytran 3123AK reference accelerometer set is used.


AcSoft’s equipment is located in an air conditioned, purpose- built laboratory and is calibrated to nationally traceable standards. Return shipping is free of charge – within the UK – and the company can also arrange collection of kit, if required.
