Spectrographical Analysis of U235 with a Hollow Cathode Discharge Tube

Hollow Cathode Discharge Initiation and Fast Starting Cathode

Conditioning of the insert inside a hollow cathode is believed to be important to ensure reliable discharge initiation and subsequent cathode operation. The desorption of contaminates is reported from hollow cathodes as a function of heater power to quantify cathode conditioning characteristics and identify factors that might prevent the fast initiation of a discharge. In addition to conditioni...

Pressure effect on a tandem hollow cathode discharge in argon

-BΣu band spectra in a hollow-cathode glow discharge

An excitation-emission model for the H2 IΠ +/− g −BΣu transition has been developed based on the coronal equilibrium. Within the framework of the adiabatic theory, the vibronic transition probability is calculated instead of the Franck-Condon factor. The ro-vibrational temperatures are evaluated through the experiment carried out in a low-density hollow-cathode plasma. The evaluated temperature...

Surface Modification of Titanium Alloys in a Non-Uniform Glow Discharge with Hollow Cathode

The characteristics of the non-uniform glow discharge with the effect of the hollow cathode (EHC), on which the chosen regimes of nitriding the surface of titanium alloy VT6 are considered. Experimental results of the influence of inhomogeneous plasma in a pulsed regime of processing on the structure and microhardness of the treated surface are resulted.
