Аннотация:For the first time it is experimentally demonstrated on the JET tokamak that a combination of a low
impurity concentration bulk plasma and large magnetohydrodynamic instabilities is able to suppress
relativistic electron beams without measurable heat loads onto the plasma facing components. Magnetohydrodynamic simulations of the instability and modeling of the postinstability plasma confirm the prompt
loss of runaways and the absence of regeneration during the final current collapse. These surprising
findings motivate a new approach to dissipate runaway electrons generated during tokamak plasma
