Description

Nuclearites that are hypothetical super-heavy exotic particles and may be important components of the dark matter in our Universe. The nuclearites may have a typical velocity of ~220 km/s, whereas interstellar meteoroids will have geocentric velocities larger than 72 km/s corresponding to a sum of escape velocity from the solar system and the velocity of the earth around the Sun. We are studying the possibility to search for such fast moving particles by using very high sensitivity CMOS cameras. We also propose co-observations with EUSO-TA to check the slow trigger application and to help the analysis of the observational data of EUSO-TA. Currently, we observed many meteor events by a single and a stereo camera system. We can estimate the observable mass range of the nuclearites and the interstellar meteoroids from the sensitivity of the camera system for these fast moving events using the observed meteor events. Observable flux limits are estimated for these mass ranges. Future plans will be also reported in this paper.
