Early on, one of the big issues that Rossi was said to have had to deal with was the control of his reactor. His early reactors were not stable.
The Cat and Mouse architecture is an attempt to make his reactor more stable. This two tiered system might use the Mouse as a stabilization and control mechanism to keep the optimum heat range of the Mouse at about 400C. That is achieved by sizing the micro-particles at a resonant black body temperature at 5 microns. When the heat of the reactor exceeds that 400C temperature, the Mouse becomes increasingly inefficient as the Hot-Cat reactor temperature increases toward 1000C where the Cat’s heat range is optimized with a particle size of 2 microns. At 1000C, the mouse is completely detuned and the pumping from the Mouse is minimized or effectively disabled. This dead Mouse puts a damping conduction on the Cat so that the Cat’s temperature is mostly limited to something under 1000C.
