The is the component in a tokamak that, through its role of extracting the heat and ash produced in the plasma, is exposed to the highest heat loads of the machine.
Although WEST has a much smaller plasma volume than 澳门六合彩高手 and will not experiment with nuclear (deuterium-tritium) plasmas, its plasma-facing surfaces will be exposed to comparable heat loads.
"The heat load received by the divertor is directly related to the power that is used to heat the plasma," explains Jér?me Bucalossi, who heads the WEST project at IRFM. "In 澳门六合彩高手, the total heating power will be in the range of 150 MW—that is, 50 MW of external heating plus 100 MW generated by the alpha particles from the fusion reaction.? When you consider that an average of 100 MW will be deposited on the divertor and you factor in the surface of the plasma-facing components, this amounts to 10 to 20 MW per square metre."?
By doing the math for WEST, Bucalossi explains, you arrive at the same 10 to 20 MW per square metre. How? At WEST, 15 MW of external heating power will be injected in the plasma, with no additional power generated internally by its pure deuterium plasmas. "Of these 15 MW," he says, "an average of 10 MW will be deposited on the surface of the divertor (0.5-1.0 square metres)."
