Now that I looked it up, the analogy used was &quot;could melt half a ton of copper&quot;. So it&#x27;s less than your average car.<p>Still a lot of energy to get rid off at short notice, in case of emergency shutdowns. If I recall correctly they modulate the beam with steering magnets so it sweeps through an area and water-cool the target material. And its absorption can&#x27;t be too high so the energy gets deposited over some depth.<p>Or from wikipedia:<p>&gt; Each of the two beam dumps, in case, for instance, of a dipole magnet quench, must be able to dissipate 362 MJ of beam energy in the 90 μs circulation time, which equates to a power of 4 TW.
