electron cyclotron resonance source[i′lek‚trän ′sī·klə‚trän ′rez·ən·əns ‚sȯrs]
A source of multiply charged heavy ions that uses microwave power to heat electrons to energies of tens of kilovolts in two magnetic mirror confinement chambers in series; ions formed in the first chamber drift into the second chamber, where they become highly charged. Abbreviated ECR source. Also known as electron cyclotron resonance ion source (ECRIS).
