Be metastable st<strong>at</strong>e (MS) tracking in ERO<br />
The system <strong>of</strong> 2 balance equ<strong>at</strong>ions<br />
can be solved analytically . . .<br />
ADAS, T e =1eV, n e =2*10 12 cm -3<br />
Effective r<strong>at</strong>es:<br />
1,2) transitions between "GS" <strong>and</strong> "MS"<br />
3,4) ioniz<strong>at</strong>ion from "GS" <strong>and</strong> "MS"<br />
5,6) line intensity (PEC – photon emission<br />
coefficient), contributions from "GS" <strong>and</strong> "MS"<br />
MS resolved approach allows to tre<strong>at</strong> in ERO<br />
effectively the slow relax<strong>at</strong>ion between triplet<br />
<strong>and</strong> singlet levels – important if MS<br />
popul<strong>at</strong>ion affected by extra processes <strong>and</strong><br />
<strong>at</strong> high <strong>plasma</strong> parameter gradients<br />
