Abstract
Description of computer code developed for processing images obtained in pepper-pot emittance measurement technique, which allows estimating emittance in single measurement. The code uses pepper-pot mask image on a scintillator screen obtained by means of laser-plasma radiation. This image is used to find positions of holes of the mask and its rotation angle. Pepper-pot techinique is applied to measure emittance of carbon ion beam extracted from laser produced plasma, generated by CO2-laser pulses with the focal power density on the target of about 1011 W/cm2. Results of image processing and calculating emittance are presented.
