- Abstract
- In the Reversed Field Pinch RFX-mod at the highest
plasma current of 2MA, when error fields are not
effectively feedback controlled, localized thermal
loads up to tens of MW/m
2
can be produced. The graphite tiles
withstand such high power loads, but their high H r
etention makes the density control extremely diffic
ult.
Several wall conditioning techniques have been opti
mized in the last campaigns, including helium glow
discharge cleaning, with dedicated experiments to i
dentify the conditions of better uniformity and eff
ectiveness,
and wall boronization by diborane glow discharges o
f different duration with samples exposed and analy
zed to
study the uniformity, thickness, erosion and redepo
sition of Boron. More recently, Lithium conditionin
g has
been applied for the first time in a Reversed Field
Pinch. The main results are discussed in this cont
ribution.
Lithization leads to important operative advantages
: a significant improvement of the density control
is obtained.
Densities up to n/n
G
?
0.5 can be produced in a controlled way. At the sa
me value of input power, plasmas at
higher densities can be sustained. However, due to
the short particle confinement time, such densities
are
reached with high rates of gas puffing. The resulti
ng profiles at high density are edge peaked. A Lit
hium
multipellet injector, aiming at a more uniform depo
sition, has been also tested. (literal)
