1. Linear polarization: wavelength dependence
... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...

3. Energetic Particles
... Energy . ... The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much, much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ... Typical energy of an electron in the polar aurora. 40,000 ev . ... 50,000 ev . ...

Title/Abstract Page: Resonant inverse Compton scattering . ... For a hot polar cap which emits soft photons, RICS can constrain the maximum energies of electrons (or positrons) accelerated in the polar gap in the following two ways: the energy loss competes with acceleration, or by limiting the acceleration length through pair production. ...

9. Removal of particle hits
Next: Background Definition Up: Echelle Spectra Previous: Order Definition . ... Their removal is a rather delicate step, because in high-contrast images (such as well-exposed echelle spectra) there is always a danger of damaging the scientific contents of the frame. Particle hits can be removed from scientific exposures by splitting the exposure and comparing spectra of the same target obtained under the same instrumental configuration. ... Note that the background has been subtracted already. ...

11. Particle Background Rejection
Next: Field of View Up: CCD Scientific Performance Previous: Back Illumination . The CCD acts as a storage medium, and with frame times of the order seconds, there is no obvious method of employing prompt co-incidence rejection of charged particle events. ... In conventional CCDs, a m track length results in an equivalent energy deposition of 5 - 6 keV, and significant confusion with X-ray events arises. ... A trade-off between rejection efficiency and spectroscopic efficiency is required. ...
