I have not seen new slides and I was not there for the lecture, but my impression is they have now set up the mass spectrometer in a loop, where the gas passes through the spectrometer into the cell, out again and around and around. The main reason that knowing (or appreciating) that the mass spectrometer was close to the device or built into the device now, as opposed to earlier - was because the operating results have been also greatly improved in the past few months . thus, we are thinking that there was the possibility of an added magnetic field being responsible or partly contributory to the bigger gain. The magnetic field seems to fit well into many recent offshoots of a Letts/Cravens effect where a small added field makes a large boost in LENR output. We cannot be sure that this is relevant to Mizuno without learning more details. However, in the MIT presentation - where they were using 300 meters of thin nickel wire, wrapped around a mandrel with many turns - instead of the much thicker and fewer turns of wire in other past experiments - that too could be where an added magnetic field originates - in the mandrel itself. However, this coil is ostensibly unpowered in the experiment IIRC. Not only that but the wire is uncoated, so an amp-turn equivalent situation is hard to imagine due to shorting. The question then would be something like this: could a small magnetic field of 500-800 gauss be created during operation of the Mizuno device by induction from the heating coil to the mandrel, or else by positive ion contact with the mandrel coil?
