A simple quasi-analytic model is developed for the dynamics of electron cloud generated by synchrotron radiation of the beam in the LHC beam pipe. The model allows to obtain a multipacting condition for the LHC parameters, takes into account the space charge effect and predicts an equilibrium density of the electrons. Based on this model, we find the electron lifetime and estimate the energy de...

We present the results of measurements ion composition plasma generated by an accelerated electron beam in forevacuum pressure range. It has been found that main contribution to ionization processes comes from electrons. shown that, during electron-beam evaporation metal or ceramic targets, number ions evaporated materials significantly exceeds produced residual atmosphere and admitted gases. T...

The recent interest in size-dependent deformation of micro- and nanoscale materials has paralleled both technological miniaturization and advancements in imaging and small-scale mechanical testing methods. Here we describe a quantitative in situ nanomechanical testing approach adapted to a dual-beam focused ion beam and scanning electron microscope. A transducer based on a three-plate capacitor...

We present hybrid PIC simulations of fast electron transport and energy deposition in pre-compressed fusion targets, taking full account of collective magnetic effects and the hydrodynamic response of the background plasma. Results on actual ignition of an imploded fast ignition configuration are shown accounting for the increased beam divergence found in recent experiments [J.S. Green et al., ...

Electron beam induced deposition can be applied as a direct write technique for the creation of 3 dimensional nano-scale structures. The technique does not require lift-off and mask based process steps and therefore has potential for application in rapid prototyping for nanotechnology, with a high degree of flexibility. The material quality and microstructure of the deposition however, is usual...
