HARİCİ UYGULANAN MANYETİK ALANIN MİLİMETRE DALGA/TERAHERTZ DEDEKTÖRÜ OLARAK KULLANILAN PARILTILI DEŞARJ LAMBALARINDAKİ PLAZMA IŞIMA OPTİK SPEKTRUMUNA OLAN ETKİSİNİN DENEYSEL GÖSTERİMİ
Öz
Bu çalışmada, Parıltılı deşarj lambaları (GDD) içindeki plazma bölgesinde meydana gelen optik
ışımada meydana gelen, milimetre dalga radyasyon ve harici elektromanyetik alana bağlı değişimler
gözlemlenmiş ve ölçülmüştür. Milimetre dalganın (MD) tek başına uygulandığı zaman optik ışımada
görülen etkinin göreceli olarak %3 civarı olduğu görülmektedir. Elektromanyetik alanın (EM) etkisi ile
ışınımda %5’lik bir artış oluşmaktadır. 600 Gauss şiddetinde bir manyetik alanın uygulanması, plazma
bölgesi optik ışımasının milimetre dalga radyasyona karşı hassasiyetini 0.4 dB kadar arttırmıştır. Daha
yüksek manyetik alan değerlerinin denenmesi planlanmıştır.

Experimental Demonstration of the Effect of the Externally Applied Magnetic Field on the Plasma Optical Radiation Spectrum of the Glow Discharge Lamps which are used as milimeter wave/Terahertz dedectors
Öz
In this study, the optical emission from a Glow Discharge Device (GDD) lamp plasma that
is affected by both magnetic and milimeter wave electric field is observed and recorded. Milimeter wave
radiation has increased the optical emission by %3. Electromagnetic field has also increased the emission
by %5. A magnetic field of 600 Gauss has increased the optical emission sensitivity to milimeter wave by
0.4 dB. In the future, higher magnetic field values will be studied.
