The shape of the beam profile of a discharge excited XeCl excimer laser using a spiker-sustainer electrical circuit has been varied from a ‘bell’-, through a ‘top-hat’-, to a ‘camel-back’-profile by varying the delay between the spiker pulse and the maincurrent with the circuit operating in the charge-mode. Fine-tuning of the beam profile can be done by varying the charging voltage of the main ...

Commercial multi-channel energy spectrometers have good performance, they multiple input signal channels and analyzers, which can simultaneously acquire the spectrum of nuclear pulse signals. But channel this general spectrometer cannot be switched between internal an only fixed to corresponding analyzers. Hence, resolve issue, paper designed a array switching circuit. The core circuit is switc...
