    The one we used did not have the external probe. The spec may claim "sensitive down to 7 keV" but in my experience a GMC with such a small internal tube won't respond to anything below around 50 keV, and the peak response will be…

    Correct. It is a GMC-320+ coupled to a LND7317 pancake tube. This combination is sensitive down to ~20 keV, with peak sensitivity at 80-150 keV. Typical background count has been around 40-50 CPM at a variety of locations. At the…

    This is an extraordinarily comprehensive and well-documented paper. The details included of the instrumentation and calibration procedures are especially impressive. I haven't read past the first 20 pages, but I expect the findings will be equally well…

    That seems too high. MFMP got ~70 mg of 62Ni for around $1k, IIRC. That would be less than $15k/g, compared to $20k/g for your quote. Maybe there's a reverse discount for quantity...

    I have measured the coil around the reactor. The result is that the inductance is somewhat higher than calculated (1.94 mH), the capacitance is somewhat smaller than labeled (0.82 uF). The resulting resonance frequency is 3.99 kHz and the effective…

    Nice work Dan. You're probably aware of the MFMP "Bang" experiment a couple of years ago. We didn't yet have pressure measurement in place, and we did exceed the yield strength of a similar Alumina cell, with dramatic results.

    Regarding pressure vs. temperature (coil power really), below is a plot of an early test run I made. The x axis is time. Used an alumina tube. 2.5g of fuel and 15% of it is LAH. No pure Li metal included. No external H2 gas feed used. Pressure reached…

    I think what is stated in the paper (as quoted by Axil) is that they measured a drop of 0.105 volts across a 1 ohm series resistor. This corresponds to a current of 0.105 amperes. If the steady-state voltage across the cell is…

    In France law about insults and libeling seems quite sensible, even if practice is very tricky.

    First you have to complain if the attack was an insult, or a libel.
    an insult is just a nasty word without claims, cannot be verified, and it is forbidden…

    At last, Weaver has said something with useful semantic content.
    That is a quote from Frank Zappa, from the album "Apostrophe". The hit song in there was "Don't Eat The Yellow Snow".

    I used some left over solution from a PC short run I did about 20 years ago. It was originally about 1 liter of solution made up from a bag of crystals bought at Jameco or Frye's . The unused portion was stored for at least 15 years in a soda…

    I had good results in surface cleaning of Ni foam in FeCl3 (PC etching solution). See the images at:

    Ni Foam hacking II

    Compare that surface morphology to the First image at Substrate Micro Structure, to see the effect of surface etching.

    From what we were told and shown, SKINR did not use any radiation detection, nor did they replicate our protocol, despite my sharing my lab notes and all details of the experiment.

    My impression is that it was a poorly designed…

    Well done Bob! Your design is really showing its promise now, payback for all the hard work.
