Abstract
Microtron MT 25 is an effective source of high energy photon radiation in photon activation analysis (PAA). Recent modernization of MT 25 was aimed at upgrading its parameters such as the mean accelerated electron current, quality of the beam and irradiation fields, and long-run operation stability and reliability. A fuzzy system for automated control of the current and energy of the accelerated electrons has been designed. Installation of an automated pneumatic tube delivery system for rapid sample transport between the beam position and detector will provide extension of the analytical range of PAA in the short time irradiation mode.
