Solicitation for non-radioisotopic insect sterilization systems

In a document published on October 30, 2018, the US Department of Energy is seeking proposals for the development of a self-shielded irradiator to be used for the sterilization of insects in support of the Sterile Insect Technique. The purpose is to use non-radioisotopic sources (e.g. x-ray or electron beam irradiators) in lieu of high-activity radioisotope sources. The technical description states:

The device needs to be capable of high throughput processing, preferably including a conveyer system. A device that can be installed in-line with the insect processing equipment would be ideal. The device must meet the dose delivery and dose uniformity requirements for SIT applications: typically 20 – 500 Gy and a Dose Uniformity Ratio below 1.5, preferably below 1.3. The device needs to be reliable, robust, and sustainable in challenging operating conditions including unpredictable electrical power, environmental control (temperature and humidity), and water supply systems. The device should be easy to operate and maintain, and be cost competitive with existing radioisotope source-based irradiators.

The selected projects can be funded as part of the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Program.
