18 Instabilités et formation de patterns dans les électrons relativistes: observations directes et modélisation

In this work we presented the first 3D numerical model of an electron bunch detector based on coherent Smith- Purcell radiation, capable of profiling femtosecond long

Figure 2c presents the pitch angle ratio of electrons measured by the HOPE (oxygen, proton, and electron) instru- ment on the Van Allen Probes. The pitch angle ratio is de fined as

The incoherent radiation from a relativistic beam is also emitted but its intensity is only proportional to the number of electron per bunch while in the case of coherent

The values obtained with the form of the self-interaction correction giving better results are compared with very recent values obtained using the Hartree-Fock method and

Two sets of examples are given: first, how superparamagnetism can be fought by fabricating thick self-organized structures, and second, what new or improved functionalities can
