The IFMIF-DONES (International Fusion Material Irradiation Facility-DEMO Oriented NEutron Source) facility is being designed with the general objective of providing irradiation of representative samples of power fusion machine materials under prototypical conditions. A linear accelerator will deliver deuterons at high intensity to circulating lithium in a loop, which will produce neutrons capable of obtaining the required damage conditions. As a result of this process, radionuclides will be produced as a by-product, which is characterized by several degrees of mobility. Shielding and radiation protection measures will be required in the facility. IFMIF-DONES will be classified as a first class radioactive facility according to national regulations, with Spain being the European candidate to site the facility. Several aspects of the main safety instructions affecting the facility's design are explained and discussed in this paper.
This paper presents a circularly polarized patch array in 37 GHz frequency, integrated in a narrow band application (BW < 1%) for signal detection. The designed array has to fulfill some specific requirements related to its radiation pattern (monopulse in the horizontal pattern and cosecant shape in the vertical one); other significant requirements are: circular polarization (RHCP with axial ratio under 3 dB), low side lobes (-20 dB below the main lobe) in the sum pattern of the monopulse, and high gain (greater than 32.5 dB).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
