Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Cold surface condensation characteristics of vibrationally excited gaseous chloroform (CHCl3) molecules have been investigated. Continuous-wave CO2 laser emission lines between 934.9 and 929.0 cm-1 were used for excitation of the carbon atom dependent binary vibration of the gaseous chloroform molecules mixed with He or N2 carrier gases. Gas mixtures were subsonically flowed through a coaxial cylindrical irradiation chamber (IC). The cold IC surface escaped fractions (cuts) of the vibrationally excited chloroform were increased more than 15% when natural chloroform molecules, whose 12C isotopic abundance is 98.9%, were used with a N2 carrier gas. With a He carrier gas, however, changes in the cut were not observed. Separations of isotopic chloroform by selective vibrational excitation were also observed with the enrichment factors between 1.01 and 1.15 under certain IC temperature conditions.
