  2. Activity report /Year 2005: scientific staff • 3 permanent scientific collaborators ( 2 on EPFL granting) • o Philippe-A. Buffat (still!!!) director • o Pierre A. Stadelmann vice-director • (1 on projects granting+temporarily on B. Garoni position) oMarco Cantoni • 1 non-permanent (still not!) scientific collaborators • (on projects granting+temporarily on B. Garoni position) • o Aïcha Hessler-Wyser • PhD students • o Yadira Arroyo (P. Stadelmann)(FNRS granting) • + Antonin Faes (A. Hessler) (collaboration with LENI/J. van Herle in 2006) • -P. Stadelmann: second student coming soon? • -P.A. Buffat: no more PhD students, but with EMPA (D. Etissa)

  3. Activity report /Year 2005: scientific staff • Kind support from other teams: • o Emmanuelle Boehm (STI/LSMX) XL30 EBSD (25% position) • Klaus Leifer (SB/IPEQ) micro-analyse (appointed Professor in Experimental Physics/Electron Microscopy Uppsala Univ. • Visiting Professor • o A. Prof. Czyrska-Filemonowicz(AGH Krakow, 4 weeks) CTI project on superalloys (A. Hessler) and hard coatings on Ti (P.A. Buffat) • Academic visitors • oDr Elena I. Suvorova(Inst. Cryst. Acad. Sci. Moscow, 6 months) P.A. Buffat collaborations, (bio-)nanoparticles • oDr Fréderic Cosandey (Uni. Rutgers USA, 1 month) collab. P. Stadelmann

  4. Activity report /Year 2005: technical / administrative staff • 3 permanent technical collaborators ( 2 on EPFL granting, 2 on projects ) - Brian Senior SEM operator retired in May 05 -Bernard Garoni mechanics and vacuum maintenance+… retired in August 05 o Danièle Laub sample prep, TEM (+SEM) operator oFabienne Bobard sample prep, FIB+SEM(+TEM), security officer oGuido Milanesi electronics, informatics, general technical support • 1 non-permanent technical collaborator(on projects granting) oColette Valotton sample preparation 30% position +new collaborator sample preparation 50% position spring 2006 Retiring collaborators will not be replaced until the new CIME's director is elected, reduced customer support and maintenance efficiency from mid 2005 up to... • 2 collab. administratifs oRuth Rouquier secretary permanent (75% Ecole+5% projets) oSalomé Favre-Tatsis secretary apprentice • 4 part time students to help to secretary, informatics backup and LN2+fluids supply The staff has decreased by 1/3 compared to the end of 2005

  5. Activity report /Year 2005: Equipment • Instruments: • No major changes despite recent progress, mainly in optics (Cs correction) and spectrometry (monochromators for EELS) • Investments expected to start again late 2006 (TEM for low contrast materials: polymers, biological samples) • last TEM brought in 1995 (CM300) • HF-2000 analytical TEM entirely serviced Dec. 2005: OK • EM430 1996 close to die, out of service since October 2005 (THT) • S-360 and cathodoluminescence still survive • no more spares • no more expertise in CIME (B. Senior and K. Leifer have left, thanks to J.-D. Ganière (IPEQ) for his support)

  6. OK, old,overloaded large breakdown overloaded Activity report /Year 2005: Equipment SEM: 4132 hours TEM: 4459 hours serviceand demos: 1223 hours total: 9814 hours research:EPFL+Uni20.-/h!

  7. Activity report /Year 2005: Equipment total: 9814 hours

  8. Activity report /Year 2005: Investments • 2005 Investments / New means: • Upgrade of XL30F SEM from Windows 3.11 to Windows 2000 • OK since March 2005 • Installation of new (powerful) EDS Noran 6 • Upgrade EDS on CM20 TEM (Noran 6): • new software and hardware (2004) works fine • will be extended to get true composition maps instead of X-ray counts maps that are sensitive to thickness and composition together • Imaging plates • replacement of the photographic plates by imaging plates • no more photographic labs, room for new TEM(s)

  9. Activity report /Year 2005: Investments • 2005 Investments / New means: • Installation of Spinning Star for electron diffraction with precession (see introduction) • Osmium plasma coater will be installed early 2006 for high resolution metal coating

  10. Activity report /Year 2005: Buildings • 2005: repair of ground coating in other units introduced noise and vibrations (light effect on microscopes, but large on nerves! • summer 2005: renewing all CIME's rooms on 1st floor (2nd floor US) not yet recoated has been postponed: 2006??? • moving of offices, secretariat and PC/Macs out of the building • sample preparation facility will be reduced to an emergency service at a location still to be defined (CIME's "rez-de chaussée" (1st floor US) or other building?) • noise, vibrations (and possibly dust) for everybody! • 2006: intense vibration level due to the new Life Science building • 2006 upon: permanent vibrations due to the underground parking of the new Life science building?

  11. Activity report /Year 2005: Teaching • "2nd cycle" lectures • P.A. Buffat • Introduction à la Microscopie électronique (experimental approach) SMX+SPh 5th sem. • P.A. Stadelmann • Introduction à la Microscopie électronique (physical approach) SMX+SPh 5th sem. • Analyse et modélisation des résultats expérimentauxSMX+SPh 7th+8th)

  12. Activity report /Year 2005: Teaching • Post-doctoral course on Electron Microscopy • session in February/March 2005, autumn session cancelled because of lack of time/manpower • 2 full weeks each with morning lectures and afternoon demonstrations • requires the full CIME's staff and invited speakers/instructors: • V. Laporte IMX/LMM/, EPFL, • R. Schaublin (CRPP/EPFL), • P.H. Jouneau (INSA-Lyon) and also… • 2nd course extended to non crystalline materials researchers in collaboration with Prof. J. Dubochet and co-workers from UNIL/LAU (parallel sessions) • too many students (30 for each course) for hands-on, waiting list • TEM and SEM users training • SEM: 40 new users, large effort to improve the training quality (4-8hrs personal hands-on with F. Bobard) • TEM: 8 new users on CM20, ? users on CM300 and HF200, estimated 20 at total • EDS: 27 users

  13. Activity report /Year 2005: Collaborations agreements • "Socrates/Erasmus" collaboration with AGH (Prof. A. Czyrska-Filemonowicz): • teaching with AGH (Electron Microscopy Center / Faculty of Mining and Materials Science / University of Science and Technology, Krakow) • part of the EM lecture given in AGH by P.A. Buffat • partial financing of student exchange betweenEPFL/CIME and AGH is open 2006...: "Socrates/Erasmus" collaboration with Uppsala Univ. (Prof. K. Leifer) • Joint research agreement with Inst. of Crystallography of the Russian Academy of SciencesICRAS (Prof. M. V. Kovalchuk / Prof. V. Klechkovskaia) • At present, collaboration with Dr. E.I. Suvorova (nonoparticles, (bio-)calcium phosphates and hydroxyapatite from bones • foreseen: installation of an EM laboratory at ICRAS

  14. Activity report /Year 2005: Infrastructure and budget • New TEM for low contrast materials and BF/DF contrast quantitative interpretation • main applications: • low contrast biological samples and polymers • quantitative contrast analysis in BF, Df and WB images of crystallized materials • Main characteristics • 100-200 kV (300 kV) • long focal length and objective aperture accurately in OL focal plane • low dose • New TEM for biological sample • acquisition in collaboration with the FSV (Prof. H. Lashuel) of a second hand TEM (FEI CM10, 100kV, long focal length) for routine work in life science • Sample preparation • replacement of the cryo ultramicrotome (2006) • FIB dedicated to TEM (2006-7) • Ion milling (2006-7?)
