As initial remark to this opening talk of EPAC2000 it can cursorily be said that particle accelerators are certainly important because the salaries and pension funds of the participants to this Conference depend on the existence, the running and the construction of accelerators. More seriously, it is useful to consider the three main uses of the primary and secondary beams produced by particle ...
The discovery of pyroelectric X-ray generation in 1992 by Brownridge has led to a recent surge of interest in the use of the pyroelectric effect as a means of producing useful radiation. By heating or cooling a pyroelectric crystal such as lithium tantalate (LiTaO3) in a vacuum, a potential on the order of 100 kV can be generated. This potential is great enough to eject electrons from the cryst...
Selecting the instruments to determine the operational quantities in the neutron fields produced by particle accelerators involves a combination of aspects, which is peculiar to these environments: the energy distribution of the neutron field, the continuous or pulsed time structure of the beam, the presence of other radiations to which the neutron instruments could have significant response an...
The past half century has seen an explosive growth of the discipline that is characterized by the deposition of localized high energy densities in solid matter, by means of energetic ions produced e.g. in particle accelerators. First the fundamentals of Ion-Solid Interaction are outlined. A brief overview is given about the basic energy transfer mechanisms and the consequences of ion impact int...
Superconducting thin films have the potential to overcome fundamental limitations of bulk niobium technology that is currently implemented in linear particle accelerators. Before these thin films can successfully be implemented, systematic studies on structureproperty correlations are necessary. Here, we present the characterization of niobium nitride thin films and multilayers. We explore the ...
In this paper, we review recent developments in our efforts to get complete control over the velocity of a molecular beam. Central in these experiments is the use of a Stark decelerator, with which the velocity of a beam of neutral polar molecules can be continuously varied, using techniques akin to methods used in charged particle accelerator physics. These techniques allow for confining isola...
Particle pulses generated by laser-plasma interaction are characterized by ultrashort duration, high particle density, and sometimes a very strong accompanying electromagnetic pulse (EMP). Therefore, beam diagnostics different from those known from classical particle accelerators such as synchrotrons or linacs are required. Easy to use single-shot techniques are favored, which must be insensiti...
