In-situ, low dose rate, total ionising dose test of the cooling performance of a thermoelectric module
This work presents and discusses the design and fully automated total ionising dose test of a thermoelectric cooling module. The goal was to develop a reliable test method which can be used to measure potential total ionising dose induced degradation of the cooling performance and demonstrate this method in a long term, low dose rate experiment. Details of the tested hardware and fully automated test system are published in this work, including preliminary test results and lessons learned.
A total ionising dose, in-situ test campaign of DS18B20 temperature sensors
Comprehensive tests are being performed to identify if the Dallas DS18B20 smart digital temperature sensor is i) a potential solution for temperature monitoring during in-situ gamma irradiation tests and ii) a suitable candidate for commercial low cost space applications. This work presents and discusses an applied test methodology for total ionising dose (TID) irradiation using a cobalt-60 gamma source. Preliminary test results are also published in this paper.
The unfolded universe of elementary particles. A geometric explanation of the standard model structure
We propose a geometric explanation of the standard model of Glashow, Weinberg and Salam for the known elementary particles. Our model is a generic Quantum Field Theory in dimension four, obtained by developing along a Lorentz sub-manifold the lagrangian of Einstein and Dirac in dimension twelve. The main mechanism which gives birth to the standard model is a certain gauge fixing of triality, which permits to identify the multiplicity of fermions, as seen from the four dimensional world, with the eight unseen dimensions of the generating universe. In this way we get the known tables of particles, explaining the series of fermions and the gauge bosons. We suggest that the Higgs field dynamics could appear through a bosonization of the right handed neutrino and correspond to a displacement in the unseen dimensions. We also propose hypotheses for dark matter, and perhaps dark energy. Then we suggest predictions to go beyond the standard model.
