摘要:
An ultrahigh vacuum compatible cooled ionizer suitable for use with a quadruple mass spectrometer has been constructed. It allows one to monitor rapidly changing signals of condensable gases as are commonly encountered in modulated molecular beam studies of surface reaction kinetics with minimal distortions due to adsorption/desorption phenomena within the ionizer. ©1996 American Institute of Physics.

摘要:
An extended application of the magnetron sputtering discharge is described. The discharge, called a magnetically confined discharge in the experiments, is pumped in a pulse mode to produce and excite copper vapor atoms for laser operation. Copper atom densities adequate for laser action (∼1014cm−3) are obtained in the discharge at temperatures below 400 K. Laser operation is expected in the experimental apparatus with fast‐rise pulse pumping. ©1996 American Institute of Physics.
