I notice there have been several provisional applications for an "X-Rays transparent reactor" throughout the years. I wonder if it's for an X-Ray activation system for the reaction, that could be important. It could have some implications for third party observations in the past: for instance Francesco Celani measured energetic gamma peaks (counts only) during the January 2011 demo. What if Rossi tried to use an X-ray generator?
