He added mathematical morphology to the topics regularly covered; Jean Serra and Gerhard Ritter are among those who have contributed. In , he joined Professor Wollnik Giessen University and Karl Brown SLAC in organising the first international conference on charged-particle optics, designed to bring together opticians from the worlds of electron optics, accelerator optics and spectrometer optics.
This was so successful that similar meetings have been held at four-year intervals from to the present day. Peter Hawkes organised the meeting in Toulouse and has been a member of the organising committee of all the meetings. He has also participated in the organization of other microscopy-related congresses, notably EMAG in the UK and some of the International and European Congresses on electron microscopy as well as three Pfefferkorn conferences. He is very interested in the history of optics and microscopy, and recently wrote long historical articles on the correction of electron lens aberrations, the first based on a lecture delivered at a meeting of the Royal Society.

Examples are the Energy-dispersive X-ray spectroscopy EDS detectors used in elemental analysis and Cathodoluminescence microscope CL systems that analyse the intensity and spectrum of electron-induced luminescence in for example geological specimens.
In SEM systems using these detectors, it is common to color code the signals and superimpose them in a single color image, so that differences in the distribution of the various components of the specimen can be seen clearly and compared. Optionally, the standard secondary electron image can be merged with the one or more compositional channels, so that the specimen's structure and composition can be compared. Such images can be made while maintaining the full integrity of the original signal, which is not modified in any way. Materials to be viewed under an electron microscope may require processing to produce a suitable sample.
The technique required varies depending on the specimen and the analysis required:. Electron microscopes are expensive to build and maintain, but the capital and running costs of confocal light microscope systems now overlaps with those of basic electron microscopes. Microscopes designed to achieve high resolutions must be housed in stable buildings sometimes underground with special services such as magnetic field canceling systems.
The Living Thing / Notebooks : Signal sampling
The samples largely have to be viewed in vacuum , as the molecules that make up air would scatter the electrons. Various techniques for in situ electron microscopy of gaseous samples have been developed as well. The low-voltage mode of modern microscopes makes possible the observation of non-conductive specimens without coating. Non-conductive materials can be imaged also by a variable pressure or environmental scanning electron microscope.
Small, stable specimens such as carbon nanotubes , diatom frustules and small mineral crystals asbestos fibres, for example require no special treatment before being examined in the electron microscope.
Samples of hydrated materials, including almost all biological specimens have to be prepared in various ways to stabilize them, reduce their thickness ultrathin sectioning and increase their electron optical contrast staining. These processes may result in artifacts , but these can usually be identified by comparing the results obtained by using radically different specimen preparation methods. Since the s, analysis of cryofixed , vitrified specimens has also become increasingly used by scientists, further confirming the validity of this technique.
