Talk:Explosively pumped flux compression generator
=Popular?
Clearly lots of discussion, but what this article needs is some *facts* on
- real research projects
- real countermeasures
- depolyed examples
- incidents of use (experiments, alledged or confirmed)
EPFCG: translation from french page
Because the french page has much more detail, various interesting diagrams, etc, I thought the english page could be improved by merging the (translated) French page with the current info here. I will start doing this at some point soon. My translation is at Talk:Explosively pumped flux compression generator/Translation from french page. --Dashpool 02:17, 7 December 2006 (UTC)
Richard 88.96.19.102 02:50, 11 December 2006 (UTC) Reality Check: While it's interesting that Uranium Rhondium Germanium goes superconducting at 280mK and 8 Tesla, bear in mind that 280 milli kelvin is incredibly cold, eg. below the boiling point of the common isotope of Helium, and only accessible using Helium-3 or a dilution refrigerator.
A superconductor has a critical current density as well as a critical field, it does not follow that a superconductor that is stable at 8 Tesla will also carry 1 million amps.
The magnetic field in NMR must be applied for a reasonable length of time (eg. 5 x T1) in order that the nuclear spins relax into equilibrium. A superconducting magnet that provides a constant field allows the nuclear spins to be polarised by coming into thermal equilibrium.
A pulse that is only microseconds long is probably of insufficient duration to allow the nuclei to reach equilibirum, so there will be no nuclear magnetisation to detec NMR from.
