The EBSN2019 will take place at the LPS, Orsay and is being organized by Mathieu Kociak (CNRS), Javier Garcia de Abajo (ICFO), Albert Polman (AMOLF), and Luiz Tizei (local committee, CNRS). More information at www.ebsn2019.org

Christian Colliex was awarded the medal “Vernon E. Cosslett” by the IFSM – International Federation for Societies of Microscopy, to honour his outstanding contributions in the field of microscopy and related techniques.

The medal was given at the closing session of the conference IMC 19, at the Sydney International Convention Centre, by the IFSM president Kazuo Furuya, and the Awards Committee Chair, Joachim Maier. The "Vernon E. Cosslett” medal is one of four medals given every four years at the international congress. Read more »

While setting up the 30 keV mode of CHROMATEM on site, we got a sub-5 meV zero-loss peak at 30 keV (40 meV at 1/1000). Great achievement!

The deadline for abstract submissions for JEELS 2018 is approaching fast. March 15th is just a few days away. For submissions, please use the template and procedure described here:

The meeting will take place in the beautiful island of Porquerolles, France on the IGESA Porquerolles center between June 11th and June 14th in 2018. We hope to see you there.

The NION machine is still hidden in wooden boxes, with a full team ready to make it deliver some meVs soon...

We just received the new STEM-CL Mönch 4107  from Attolight to fit our NION CHROMATEM machine. Compare our best VG version (left) to the Attolight one (right). Congrats for the excellent work, guys at Attolight!

First spectral resolution tests have been performed on the NION CHROMATEM machine. The machine features 8 meV resolution at 60 keV with 7 pA in the electron probe. This is more than 3 times better than foreseen at the launch of the project in 2011, 40 times better than with current technologies available in our lab, and close to the best performances ever published.
More performances reports soon!

The thesis work of Adrien Teurtrie has been recently awarded by the poster prize at the Louis Néel workshop 2017 for his contribution on "Towards spin-polarized transport in Ca-doped Bismuth Iron Garnet thin films". This work is currently carried out between the STEM group of the LPS and the FOX group of the GEMaC lab.

For its first edition, the Castaing Prize, Grand Prize of Sf?, was awarded to Marcel Tencé for his pioneering developments in instrumentation in electron microscopy, and in particular in spectral imaging and EELS detection.
Marcel Tencé is a research engineer in the STEM group of the LPS, where he was recruited in 1981 to develop a digital scanning electronics for the LPS VG microscope. Since then, Marcel Tencé has been constantly pushing the performances of scanning electronics towards unique performances. He was also very interested in the optimization of the energy loss spectroscopy (EELS) experiments, and it is quite natural that he was able to implement one of the very first spectral imaging systems. The performances of his inventions have enabled many scientific firsts, ranging from the first detection of single atoms by EELS to nanometric mapping of plasmons first by EELS and then in combination with cathodoluminescence. His inventions have spread throughout the world, be it through numerous academic or industrial collaborations, via for example Orsay Physics that he co-founded or the company Attolight that uses his scanning system.

The thesis work of Sophie Meuret focused on the study of the emission statistics of the photons created by the electron irradiation of nano-objects (cathodoluminescence). Sophie Meuret has in particular discovered a photon bunching effect specific to cathodoluminescence, an effect which she has exploited for the measurement of the lifetime of nanometric objects. This work was carried out in the STEM group of the LPS, under the direction of M. Kociak and L. Tizei, and financed by the DGA, CNRS and the TEMPOS Equipex. It has benefited from collaborations with J. Garcia de Abajo (ICFO, Barcelona, Spain), F. Treussart (LAC, Orsay, France), T. Auzelle, B. Daudin and B. Gayral (Institut Néel, Grenoble, France) HC Chang (Academia Sinica, Taipei, Taiwan). Read more »
