AbstraktAbstract

An electron imaging system has been developed for spatial information in coincidence Instrumental Neutron Activation Analysis. In our technique, a beta-radioactive sample is scanned at once where the electrons are detected in the position-sensitive Timepix detector in coincidence with γ-rays. Following our previous work where the detector was used in close-contact sample geometry, we have built a devoted non-contact electron optic system to focus coincidence electrons for imaging measurements with enhanced spatial resolution and reduced blurring. This contribution describes the electron focusing system and its evaluation.
