This is an expanded and revised second edition, presenting accurate
and comprehensive information about our leading thermal scientists
to current and future generations. In our globalized world, most
researchers in thermal analysis do not know each other in person
and are not familiar with each other's achievements. This volume
provides the reader with an up-to-date list of the prominent
members in this community. The publication contains only living
scientists. The selection is based partly on several decades of the
editors' personal professional experience and also partly on the
opinion of the Regional Editors of the Journal of Thermal Analysis
and Calorimetry.
The field of electron and ion optics is based on the analogy
between geometrical light optics and the motion of charged
particles in electromagnetic fields. The spectacular development of
the electron microscope clearly shows the possibilities of image
formation by charged particles of wavelength much shorter than that
of visible light. As new applications such as particle
accelerators, cathode ray tubes, mass and energy spectrometers,
microwave tubes, scanning-type analytical instruments, heavy beam
technologies, etc. emerged, the scope of particle beam optics has
been exten ded to the formation of fine probes. The goal is to
concentrate as many particles as possible in as small a volume as
possible. Fabrication of microcircuits is a good example of the
growing importance of this field. The current trend is towards
increased circuit complexity and pattern density. Because of the
diffraction limitation of processes using optical photons and the
technological difficulties connected with x-ray processes, charged
particle beams are becoming popular. With them it is possible to
write directly on a wafer under computer control, without using a
mask. Focused ion beams offer especially great possibilities in the
submicron region. Therefore, electron and ion beam technologies
will most probably playa very important role in the next twenty
years or so."
