In the present work, the determination of the electromagnetic radiation and shielding studies of a new designed and constructed portative plasma device have been reported. For this aim, the electromagnetic interference (EMI) measurements are performed. The device works with high voltage up to 2 kV depending on its filling gas pressure and contains a couple of terminals in the low pressurized chamber to form plasma structures confined in terms of electrical and magnetic confinement. The chamber as a simple torus geometry has been operated with He gas for the plasma stability explorations. The EMI measurements have been practiced for different distances from the setup and used different shielding materials to prevent the non-ionizing radiation. According to detailed tests with different shielding materials (Swatter, Square, Honeycomb) it is observed that the shape of the shielding material is very important for the optimum shielding results.

Yeni Bir DC Plazma Cihazında İyonize Olmayan Radyasyonun Belirlenmesi ve Ekranlama Çalışmaları

Öz

Bu çalışmada, yeni tasarlanan ve üretilen portatif plazma cihazının elektromanyetik alan ölçümleri ve ekranlama çalışmaları yapılmıştır. Cihaz, dolum gazı basıncına bağlı olarak 2 kV’a kadar yüksek voltajla çalışmaktadır ve düşük basınçlı haznede elektrik ve manyetik alanları hapsedilmiş plazma yapıları oluşturmak için bir çift terminal içermektedir. Basit bir torus geometrisi olan hazne, plazma kararlılığı araştırmaları için He gazı ile çalıştırılmaktadır. Cihazdan farklı mesafelerde elektromanyetik alan değerleri ölçümü yapılmış ve iyonlaştırıcı olmayan radyasyonu önlemek için farklı ekranlama malzemeleri (Swatter, Square, Honeycomb) kullanılmıştır. Farklı malzemelerle yapılan ölçüm sonuçlarına göre, optimum ekranlama değeri elde etmek için ekranlama malzemesinin şeklinin çok önemli olduğu görülmüştür.
