NOTE: The guaranteed life is defined by the product of the lamp current value (typ. Nowadays, they play a central role in applied. PLEASE SEE OUR ADDITIONAL IMAGES TAB FOR FURTHER TECHNICAL INFORMATION AND DIMENSIONAL OUTLINES. The electrodeless discharge lamp of Rb atoms containing Rb vapor and buffer gas is an important component of the microwave Rb atomic clock 1,2. So, operate at the lamp current specified for the instrument in use. The buffer gas ions will then be accelerated into the cathode, sputtering off atoms from the cathode. A large voltage across the anode and cathode will cause the buffer gas to ionize, creating a plasma. Spectral profile of the dye laser output in the wavelength region 615675 nm (top) and OG spectral lines from a Fe-Ne hollow cathode lamp for calibrating the observed spectra. Download : Download full-size image Figure 6.10. However, instruments using a pulse lighting system may indicate the lamp current value as the mean value. 1 An HCL usually consists of a glass tube containing a cathode, an anode, and a buffer gas (usually a noble gas ). Experimental arrangement for recording the optogalvanic spectra of noble gases from hollow cathode discharge. The lamp current values listed above are specified as a peak value.
