- Abstract
It is measured a dependence of amplitude of alternating component of radiating discharge in helium in conic tube on discharge current. Comparison of obtained results with analogous measurements in cylinder tube is given. It is detected that striations existence area is narrower in case of conic geometry, and modulation depth of discharge radiation in conic tube is essentially less than cylinder one in case of identical other conditions. There are estimated numbers of linear and stepwise ionizations in case of different discharge current direction. It is stated that in case of discharge narrowing to anode direction main mechanism of charged particles appearing is direct helium atoms ionization by means of electron impact on general state atoms. In case of reverse current direction stepwise ionization prevails. On a basis of obtained results we considered discharge dynamic properties. It is detected that dynamic resistance behavior is inductive, in stepwise ionization mode discharge is characterized by negatron property. We pointed a possibility of noiseless light source obtain by means of conic discharge tube application.
