| Outline of Final Research Achievements |
Charging experiments on powder particles was conducted using deep ultraviolet light. First, a powder supply system using an ultrasonic sieve was developed to prevent agglomeration of particles due to adhesive force. Next, deep ultraviolet light was irradiated on free falling particles and an electric field was applied to estimate the charge amount from the distance of particles. As a result, although the charging and acceleration of the particles were successful, the charge amount was lower than the theoretical value by about two orders of magnitude. Since particles move also to the positive electrode side, this result might be considered to be the effect of static electricity generated by friction at the time of particle supply.
