  Nuclear fusion in ultra-dense deuterium D(-1) induced by 0.2 J pulses with 5
ns pulse length ejects ions with energies in the MeV range. The ns-resolved
signal to a collector can be observed directly on an oscilloscope, showing ions
arriving with energies in the range 2-14 MeV u-1 at flight times 12-100 ns,
mainly protons from the fusion process and deuterons ejected by proton
collisions. Electrons and photons give almost no contribution to the fast
signal. The observed signal at several mA peak current corresponds to 1x10^13
particles released per laser shot and to an energy release > 1 J assuming
isotropic formation and average particle energy of 3 MeV as observed. A movable
slit close to the laser target gives spatial resolution of the signal
generation, showing almost only fast ions from the point of laser impact and
penetrating photons from the plasma outside the laser impact point. The initial
photon pulse from the fusion process is observed by a photomultiplier detector
on-line.
