    Graduate Trouble Making a Penning Ion Source

    The hydrogen gas is igniting (as in combustion) or arcing? If the former, it would seem one has an air (oxygen) leak, or free F through decomposition of teflon. H + F = HF is a fairly energetic reaction. Is the Penning source a negative H- ion supply?

    Some thoughts about self-education

    I should indicate that it was a music lesson in 4th grade class. As I recall, the lesson was part of a music appreciation in which we listened to 20 pieces of classical music over several weeks, and about mid-year there was a test in which we had to identify each piece. I scored 100%. I...

    Tungsten Cubes for STEM Education — Looking for Feedback

    I had the same thoughts. Without other cubes of different metals, e.g., Mo, Fe, Cu, Al, there a limited uses for a single cube. One could measure mass, volume (geometrically with a caliper and immersively with a fluid in a graduate beaker. The mass of a 1 cm x 1 cm x 1 cm ( = 1 cm3) cube...

    Undergrad Very high energy photons in space

    "Very high energy photons" is an interesting topic. The OP poses an interesting, although awkward, question with respect to PeV or GeV photons. In between there are TeV electrons. I would emphasize from 1 GeV to 1 PeV is 6 orders of magnitude: 109 to 1015. In terrestrial accelerators, we are...

    MCNP vs Serpent pin-cell burnup discrepancy in keff evolution

    Achieving 30 GWd/tU within 250 days is impressive. I must read the text files before asking further questions or making comments. It would be interesting to compare with other codes like CASMO, WIMS and OpenMC.
