AbstractWe study the effect of chromospheric bombardment by an electron beam during solar flares. Using a semi-empirical flare model, we investigate energy balance at temperature minimum level and in the upper photosphere. We show that non-thermal hydrogen ionization (i.e., due to the electrons of the beam) leads to an increase of chromospheric hydrogen continuum emission, H− population, and absorption of photo-spheric and chromospheric continuum radiation. So, the upper photosphere is radiatively heated by chromospheric continuum radiation produced by the beam. The effect of hydrogen ionization is an enhanced white-light emission both at chromospheric and photospheric level, due to Paschen and H− continua emission, respectively. We then obtain white-light contrasts compatible with observations, obviously showing the link between white-light flares and atmospheric bombardment by electron beams.

A method for measuring electron beam profiles is developed with the goal of evaluating the focus of color CRT displays. To increase measurement speed, a two-dimensional sensor is used and the electron beam profile is measured from the light emission intensity of phosphor dots. The portion blocked by the shadow-mask is measured by applying a magnetic field from the glass panel side. The electron beam profile obtained by this method and the results of visual focus evaluation by character pattern are compared. Good agreement with the visual evaluation results is obtained using two types of beam cross-section areas in the high and low intensity regions.
