... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

... The picture shows a 2-dimensional sketch of the outflowing wind of a quasar (Elvis 2000, Astrophysical Journal , vol.545, p.63-76). In the funnel-shaped disk wind Elvis (2000) model a wind arises from a restricted range of radii on the accretion disk around the central black hole. Initially the wind makes a large angle to the disk plane (and so is roughly cylindrical). ... Looking through the quasi-cylindrical part of the wind we see UV and X-ray warm absorbers. ...

We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...

Electron-Bombarded, Back-Illuminated CCD Sensors . For Low-Light-Level Imaging Applications . ... Damage to the gate structure oxide layers from keV level X-rays will likely result in increased dark current and decreased full-well capacity. ... Figure 14 shows the increase in dark current versus incident electron energies. ... The back-thinned CCD's 'lifetime' is defined, herein, to be a 50 electron per pixel increase in CCD dark current per 16.7 millisecond integration period. ...

... Denis Puy . ... More recently, Puy & Signore (1995), from this simple description, but with a more complete chemistry (primordial , HD and LiH molecules) considered the three phases of the protoclouds supposed to be initially spherical: i) a linear evolution which approximately follows the expansion, ii) a turn around epoch ( ) when the protocloud reaches its maximum value, and iii) a non-linear evolution or the collapse of the protocloud. ...

... Programme . ... Abstract: Chandra data taken as part of the Very Large Program (VLP) show that the X-ray spectrum in Centaurus A's jet steepens with increasing distance from the jet axis. ... Electrons with sufficient energy to emit synchrotron X-rays must be accelerated locally to the knots, since their energy loss timescale is short compared with any dynamical timescale associated with fluid motion. ...
