The versatility of laser accelerators in generating particle beams of various types is often promoted as a key applicative advantage. These multiple types of particles, however, are generated on vastly different irradiation setups, so that switching from one type to another involves substantial mechanical changes. In this letter, we report on a laser-based accelerator that generates beams of either multi-MeV electrons or ions from the same thin-foil irradiation setup. Switching from generation of ions to electrons is achieved by introducing an auxiliary laser pulse, which pre-explodes the foil tens of ns before irradiation by the main pulse. We present an experimental characterization of the emitted beams in terms of energy, charge, divergence, and repeatability, and conclude with several examples of prospective applications for industry and research.

In the framework of the MICADO (Measurement and Instrumentation for Cleaning And Decommissioning Operations) European Union (EU) project, aimed at the full digitization of low- and intermediate-level radioactive waste management, a set of 32 solid state thermal neutron detectors named SiLiF has been built and characterized. MICADO encompasses a complete active and passive characterization of the radwaste drums with neutrons and gamma rays, followed by a longer-term monitoring phase. The SiLiF detectors are suitable for the monitoring of nuclear materials and can be used around radioactive waste drums possibly containing small quantities of actinides, as well as around spent fuel casks in interim storage or during transportation. Suitable polyethylene moderators can be exploited to better shape the detector response to the expected neutron spectrum, according to Monte Carlo simulations that were performed. These detectors were extensively tested with an AmBe neutron source, and the results show a quite uniform and reproducible behavior.

Actual Computer

A computer method has been developed which facilitates the rapid use of the Philips 300 goniometer stage for quantitative diffraction contrast analyses of lattice imperfections in thin-foil specimens. Using this method it is a straightforward matter to obtain 20 (or even more) different two beam conditions on a single randomly oriented grain in a polycrystalline specimen. Furthermore, the method avoids ambiguity in determining the sense of the atomic displacement of planar defects. Thus it is particularly useful for the precise characterization of stacking faults and anti-phase boundaries. The generality of the method enables it to be used for thin-foil specimens with any crystallographic structure. Basic steps involved in the actual computer program are briefly summarized.
