  Controlled fusion with advanced fuels requires average electron and ion
energies above 100 keV (equivalent to 1.1 billion K) in a dense plasma. We have
met this requirement and demonstrated electron and ion energies over 100 keV in
a compact and inexpensive dense plasma focus device. We have achieved this in
plasma "hot spots" or plasmoids that, in our best results, had a
density-confinement-time-energy product of 5.0 x1015 keVsec/cm3, a record for
any fusion experiment. We measured the electron energies with an X-ray detector
instrument that demonstrated conclusively that the hard X-rays were generated
by the hot spots.
