Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The use of an easily reproducible neutron source reaction that produces a well-known continuous spectrum of neutrons over a range of energies is an ideal solution for some neutron detector efficiency calibrations. Fission chamber measurements of the 27Al(d,n) reaction have proven valuable for detector calibration for energies between 0.2 and 14 MeV. To complement the aluminum data, measurements were made with a fission chamber at 60 deg of the neutron spectrum produced from the 7.5-MeV deuteron bombardment of a thick natural boron target. This should enable accurate and efficient calibration of neutron detectors for the energy range between 0.09 and 19.6 MeV. Tenth-order polynomial fits to the data are provided for the region with energies between 88 keV and 2.33 MeV and the region with energies between 1.76 and 19.6 MeV.
