Seminar topic: “Determination of the natural frequencies of ultralight sensor support trusses of silicon tracking systems”
Speaker: Maribel Herrera Barrera (University of Colima, Mexico)
Abstract:
In this work, a method is developed to determine the natural frequency of highly-irradiated ultralight carbon fiber trusses. This method is based both in experimental acoustic measurements and the ANSYS-based modeling of the trusses. The structures under study are sensor supporting trusses widely used in silicon inner trackers of large experimental setups at LHC, FAIR and NICA. The result of this work will be used for studying the change in the natural frequency of the trusses after being irradiated at IBR-2 reactor of the LNP, JINR.
