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...
متن کامل-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...
متن کاملDevelopment of a laser ablation-hollow cathode glow discharge emission source and the application to the analysis of steel samples.
A novel atomic emission spectrometry comprising laser ablation as a sampling source and hollow cathode plasma for the excitation of ablated sample atoms is proposed. In this arrangement, a conventional Grimm-type discharge lamp is employed, but the polarity of the power supply is reversed so that the cylindrical hollow tube acts as a cathode and the glow discharge plasma is produced within this...
متن کاملLithium-Fed Hollow Cathode Theory
A theory for the single-channel hollow cathode (SCHC) that includes the relevant physical processes and predicts the operating parameters is presented. A SCHC consists of a cylindrical channel approximately ten diameters in length through which a working gas (taken as lithium vapor here) flows and exits as a plasma. A high current (1-100 A) is conducted into the channel by the plasma and to the...
