Hodoskoopseadme töökindlus sõltub otseselt selle elektroonikakomponentide efektiivsest
jahutamisest, kuna seadme töö käigus tekkiv soojus võib põhjustada mõõtevigade
suurenemist või komponentide kahjustusi. Samuti sarnaste seadmete jahutuse küsimus on
varasemalt olnud vähe käsitletud ning puuduvad universaalsed lahendused, mis sobiksid
konkreetsetesse töötingimustesse. Töö eesmärgiks oli projekteerida hodoskoobile sobiv
jahutussüsteem, mis tagaks selle stabiilse töö erinevates keskkonnatingimustes. Töö
käigus analüüsiti seadme soojuskoormust, uuriti erinevaid jahutusmeetodeid ning koostati
ja testiti prototüüp. Metoodiliselt tugines töö kirjanduse analüüsile, soojuskoormuste
arvutustele ning jahutussüsteemi komponentide võrdlusele ja valikule, mille tulemusel
koostati praktiline jahutuslahendus. Töö tulemusel valiti sobivaks kombinatsioon
aktiivsest ja passiivsest jahutusest, mille prototüüp tagas kriitiliste komponentide stabiilse
temperatuuri ka maksimaalse koormuse korral. Lahendus on modulaarne ja sobib
rakendamiseks nii teadusuuringutes kui ka potentsiaalsetes väliinstallatsioonides. Töö
loob eeldused edasisteks arendusteks – näiteks temperatuuri automaatne reguleerimine või
alternatiivsete jahutuslahenduste (nt vedelikjahutus) katsetamine. Esitatud süsteem on
teostatav reaalse seadme osana ning aitab tõsta müüontomograafia seadmete töökindlust
ja täpsust.
The operational reliability of hodoscopes used in muon tomography devices directly depends on the effective cooling of their electronic components. During operation, the system generates heat that can lead to increased measurement errors or even damage to sensitive components. Moreover, the topic of thermal management in such devices has been insufficiently addressed in previous research, and there is a lack of universal solutions that suit specific working environments. The aim of this thesis was to design and build a suitable cooling system for a tomographic hodoscope that would ensure stable operation under various environmental conditions. The work involved analysing the system’s thermal load, exploring different cooling methods, and constructing and testing a working prototype. Methodologically, the study was based on literature review, thermal load calculations, and comparative analysis of cooling system components, resulting in a practical and implementable cooling solution. The final design combined both active and passive cooling methods, with the prototype successfully maintaining stable temperatures of critical components even under maximum load. The solution is modular and suitable for use in both scientific research and potential field deployments. This project lays the groundwork for further developments, such as automatic temperature control and the exploration of alternative cooling technologies (e.g., liquid cooling). The presented system is technically feasible as part of a real device and contributes to enhancing the reliability and precision of muon tomography equipment.
