This document summarizes a solution target radioisotope generator technology for producing the medical isotope molybdenum-99 (Mo-99). The technology uses a subcritical system with uranium salts dissolved in heavy water as the target, and a photon source driven by an electron beam accelerator. When photons interact with the deuterons in heavy water, photoneutrons are produced causing fission in the uranium salts. This generates Mo-99 which can then be extracted. Prototypes have confirmed photoneutron production in heavy water and the technology aims to provide a domestic alternative for producing Mo-99 with less regulatory hurdles and waste compared to existing reactors.

Dr. Antonio Correia Editor - Phantoms Foundation
This document discusses methods for reducing coupling between antennas located near each other. It focuses on using periodic structures, such as corrugated metal surfaces, to provide electromagnetic shielding between antennas. Periodic structures can give the surface an inductive or capacitive impedance that attenuates electromagnetic fields and reduces coupling. Structures with quarter-wavelength deep slots can reflect plane waves with no phase reversal, further reducing coupling. While useful, periodic structures work best at wavelengths much smaller than the period. More research is still needed to develop new designs and models to improve electromagnetic compatibility between antennas.

Different Multilayer Substrate Approaches to Improve Array Antenna Characteri...TELKOMNIKA JOURNAL
The aim of this paper is to investigate deeply in multi-layer substrate technique as a way of improving the characteristics of patch array antenna for electronic scanning radar application. The basic array antenna consists of 8 patches mounted on a FR-4 substrate and operating at 3 GHz frequency. The feeding technique is microstrip technology. This structure has some disadvantages as a poor gain and a narrow bandwidth. In fact, the obtained gain value does not exceed 7 dB which could be explained by the lossy nature of the FR4 substrate. On the other side, the narrow bandwidth is caused by the microstrip limitations. For this reason, the technique of multi-layer substrate is proposed in this paper. Many approaches are investigated and the distance between the layers is studied. The design and simulations of each approach are performed under the tool Advanced Design System of Keysight Company. A comparison between simulation results of all approaches including simulation results of the basic array antenna will be analyzed.

Innovation project name:
Nanostructured coating to suppress
the effect of secondary electrons emission
on metal surfaces in communication satellites
Sk
Skolkovo Name of organization:
Plazma-Sk Ltd.
Moscow, 2016
2. At the creation and operation of communications satellites one of the key issues that determine the
technical and operational data (number of working channels, maximum power transmission path, the time of
working without crashing, total lifetime) is the process of occurrence of secondary high frequency electron
discharge in receiving and transmitting paths of satellite.
Secondary electron ultrahigh frequency vacuum discharges (UHF-SED) or in English literature "multipactor"
occur in a vacuum on the walls of the microwave waveguides and UHF resonators on dielectric windows
and inserts.
The phenomenon of UHF-SED is manifested in avalanche growth of the electron concentration at the single
surface (unilateral discharge) or between two surfaces (two-tailed discharge). UHF-SED develops rapidly
since several randomly emerged electrons or electrons formed in the residual gas and also on the surface
of the metallic or dielectric elements of UHF path as a result of exposure of cosmic radiation.
The high concentration of electrons in the system of waveguide path of the spacecraft leads to the
absorption of UHF power and distortion of the transmitted signals, as well as to the emergence of radio
interference capable to suppress the receiving UHF channel of the spacecraft. UHF-SED limits the power of
radiation of UHF generators, developing in the volume of the UHF device, at its output windows or elements
of UHF radiation transporting path.
UHF-SED leads to a limitation the maximum power that may be transmitted through the receiving and
transmission path of spacecraft, and thus it limits the number of operating channels, the maximum UHF
power of transmitting path, reduces the operation time of the UHF transmission system without crashing,
thereby disrupts the work of the all spacecraft systems and reduces the overall service life.
Another key problem - a sudden failure of the satellite, the cause of which, according to the version of the
Stanford University (2013), is electromagnetic impulse, emitted by the plasma generated from the impact of
the particles of dark space dust. Plazma-Sk Ltd. technology can be applied to solve this problem (reducing
be 2 times the satellite vulnerability to this factor).

aimed to:
3. Technology of suppression of the multipactor effect, which is a covering of surface of metal elements of the microwave
transmission system of spacecraft by a thin film thickness of ~ 1mcm of nanostructured carbon particles by a specially developed
technique.
2. The description of proposed problem solution and its advantages:
Project technology is a radical solution of problem:
Suppression of secondary electron emission without significant change of radio physical
properties of processed parts and assemblies;
Possibility to increase by more than 100% of the power of the UHF transmission path
for each satellite;
Suppression of high-frequency electromagnetic noises.
Experimental confirmation of the effectiveness of the method:
Nanocoatings obtained using ethanol gel and developed original method of processing of
metal samples by Plazma-Sk Ltd.’s technology significantly reduce the maximum values of
the coefficient of secondary electron emission (SEEC) (up to 2 times) and increase at 5-10
time the value of the first critical potential E1 (electron energy at which SEEC ≥ 1). These
results allows increase at 5 - 10 times the multipactor threshold concerning microwave
power density on the nanocarbonfilm-coated samples.

The results of testing of onboard satellite equipment element (microwave valve) covered with nanocoating, conducted by
FERRITE DOMEN Co. (St. Petersburg), have confirmed the absence of the negative impact of coating on the radio physical
properties of treated surfaces.
Project solution advantages:
Nanocarbon films have high adhesion ability and retain their properties on the suppression of secondary electron emission
over a long residence time in the air atmosphere;
Method of applying allows to cover the surface by protective films in open conditions in an air atmosphere, which greatly
simplifies and reduces the cost of technology, removes the restrictions of the size of covering parts;
Method of applying of nanostructured films does not require heating parts, which significantly expands the nomenclature of
susceptible to processing products;
Problem of covering parts of complex configuration by nanostructured films can be solved by relatively simple means.
4. Technology includes the following stages:
Obtaining of colloidal solution of nano-sized carbon.
The manufacturing technology of nanostructured
carbon particles is based on the excitation multispark
discharge in ethanol using a specially developed
technique and technical equipment. For
manufacturing and production of colloidal solution of
nano-sized carbon the original model of device has
been created.
Preprocessing of metal surfaces based on a specially
developed method to provide technical possibility of
applying of nanocoatings with acceptable adhesion.
Applying of colloidal solution of nano-sized carbon on
metal surfaces of the UHF transmission system of
spacecraft by the evaporation method or
electrophoresis.

5. Reducing the maximum values of the secondary
electron emission coefficient by to 2 times
Process of applying a nano-carbon film does not
require the use of expensive raw materials and
equipment, it is less expensive than adopted by the
authors of analogs ($0.8-1.2 million against €3-6
million at competitors)
Application of substance may be carried out in open
conditions of air atmosphere
Size of coating Is practically unlimited (applied on the
sample 8*15 cm)
Nanocoating retains its properties during a long
residence time in an air atmosphere
