Battery-powered pulsed high density inductively coupled plasma source for pre-ionization in laboratory astrophysics experiments

Battery-powered pulsed high density inductively coupled plasma source for pre-ionization in laboratory astrophysics experiments.

An electrically floating radiofrequency (RF) pre-ionization plasma source has been developed to enable neutral gas breakdown at lower pressures and to access new experimental regimes in the Caltech laboratory astrophysics experiments. The source uses a customized 13.56 MHz class D RF power amplifier that is powered by AA batteries, allowing it to safely float at 3-6 kV with the electrodes of th...

High brightness inductively coupled plasma source for high current focused ion beam applications

A high brightness plasma ion source has been developed to address focused ion beam !FIB" applications not satisfied by the liquid metal ion source !LMIS" based FIB. The plasma FIB described here is capable of satisfying applications requiring high mill rates !!100 "m3/s" with non-gallium ions and has demonstrated imaging capabilities with sub100-nm resolution. The virtual source size, angular i...
