Tube qualification phase for end stage of amplifier using single chain of amplifiers (R&D programme) - 1.5 MW / 2000s / 35- 65 MHz at VSWR 2.0 with any phase of reflection coefficient.
Prototype phase (combined power test of two identical chains of amplifiers) for 3.0 MW / 3600s / 40 - 55 MHz at VSWR 1.5 with any phase of reflection coefficient. Two RF sources (Prototype & Unit-1) will be developed and commissioned at IO site.
Bulk production (Unit-2 & Unit-3 RF sources) for 3.0 MW / 3600s / 40 - 55 MHz at VSWR 1.5 with any phase of reflection coefficient. Two more RF sources will be manufactured and commissioned at IO site
Bulk production (Unit-4 to Unit-8 RF sources) for 3.0 MW / 3600s / 40 - 55 MHz at VSWR 1.5 with any phase of reflection coefficient. Five more RF Sources will be manufactured and commissioned at IO site if decided depending on the experimental performance on ITER machine, after Start of Research Operation (SRO).
