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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

Polyimide films are materials of choice as membrane shutters of the hohlraum that contains a plastic microshell in which nuclear products are located to carry out Inertial Confinement Fusion experiments. In addition to high mechanical properties, polymer membranes must exhibit a high transparency in the infrared (IR) wavelengths range between 2.86 and 4 m (3500 and 2500 cm-1) to allow the IR assisted deuterium-tritium ice layer redistribution. UpilexTM type polyimides exhibit the desired mechanical properties but are not transparent in this wavelengths range due to the aromatic C-H stretching bands. In order to provide the required optical properties, the hydrogen atoms must be substituted by deuterium atoms.In the present contribution, we wish to report the first synthesis of a fully deuterated UpilexTM type polyimide. Optimized ways of synthesis and purification for the two deuterated monomers 3,3',4,4'-biphenyltetracarboxylic dianhydride (BPDA-d6) and p-phenylene diamine (PDA-d4) have been developed. These monomers have been used to prepare deuterated poly(amic-acid) solutions in NMP. Thermal treatment of films obtained from these solutions gives rise to deuterated Upilex type polyimide films. These films show a high transparency in the 2.86-4 m region. The synthesis and the characterization of this new deuterated polymer will be discussed.
