Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

We present a novel nuclear activation-based method for the investigation of high-energy photons and electron dynamics within the laser-plasma interaction zone. This method is based on high density activation targets which are a pseudoalloy of several selected isotopes with different photo-neutron disintegration reaction thresholds. The gamma decay spectrum emitted by the activated target is used for the reconstruction of the bremsstrahlung spectrum generated by the electrons. This allows for the reconstruction of the spectrum of bremsstrahlung photons without any anticipated fit procedures. Furthermore, the characterization of the electrons in the interaction zone is accessible immediately.The consolidated findings about the interaction mechanisms could be used to realize, control and characterize laser driven particle generation, such as a pulsed neutron source for nuclear and material sciences using special target designs and materials in a pseudoalloic compound of isotopes. An additional application is the laser assisted nuclear transmutation to produce short-lived isotopes with activities suitable for medical diagnostics and therapy.
