Özet:

 Although fluxgate sensors used for weak magnetic field measurements are highly affected by environmental factors in the space environment, they are widely preferred in space missions due to their proven performance and reliability. Environmental factors can cause major problems that may partially or completely hinder the mission of spacecraft. In this study, the effects of radiation, which is one of the environmental factors, only on the sensor core were investigated. Characterization measurements of the cores exposed to three different doses of Gamma radiation were made. It was observed that the scale factors obtained from the sensitivity measurements were close to each other with very little difference. In addition, it was observed from the noise analyzes that the noise level increased in the order of nT with increasing doses of radiation.

 Zayıf manyetik alan ölçümleri için kullanılan fluxgate sensörler uzay ortamındaki çevresel faktörlerden oldukça fazla etkileniyor olsa da uzay görevlerinde kanıtlanmış performansları ve güvenilirlikleri dolayısıyla oldukça yaygın tercih edilirler. Çevresel faktörler uzay araçlarının görevini kısmen ya da tamamen engelleyebilecek büyük sorunlara neden olacağından, bu çalışmada çevresel faktörlerden biri olan radyasyonun sadece sensör nüvesi üzerinde etkileri incelenmiştir. Üç farklı dozda Gama radyasyona maruz bırakılan nüvelerin karakterizasyon ölçümleri yapılmıştır. Hassasiyet ölçümlerinden elde edilen ölçek faktörlerinin çok az farkla birbirlerine yakın olduğu görülmüştür. Ayrıca yapılan gürültü analizlerinden artan radyasyon miktarıyla gürültü seviyesinin ise nT mertebesinde arttığı gözlenmiştir.
