2-minute Pellet Fueled LHCD Plasma
(155 pellets. Very stable speed of 0.5 km/s)
a new ITER-relevant PAM (Passive-Active Multijunction) launcher, complementing the FAM (Full Active Multijunction and replacing the 20 year old grill
a complete renewal of the power transmitter, including 16 new klystrons TH2103C (Thalès Electron Devices)The New Tore Supra LHCD system
R. Magne, P. Mollard et al.
FAM: not installed
PAM: fed with 8 “old” klystrons (Ptransmittermax~2.8MW)
end march 2010: short Tore Supra shutdown
FAM: reinstalled and connected to the first series of 8 “new” klystrons (Ptransmittermax~ 5.5MW > PFAMmax)
PAM no change (Ptransmittermax~ 2.8MW < PPAMmax)
end 2010: LHCD transmitter shutdown
FAM no change (Ptransmittermax~5.5MW > PFAMmax)
PAM connected to second series of 8 “new” klystrons (Ptransmittermax~5.5MW > PPAMmax)
Near term activities on transmitter
L. Delpech et al.
The PAM is presently the heaviest object on a Tore Supra port (~8 tons)
