A long standing enigma in plasma transport has been resolved by modeling of cold-pulse experiments conducted on the Alcator C-Mod tokamak. Controlled edge cooling of fusion plasmas triggers core electron heating on timescales faster than an energy confinement time, which has long been interpreted as strong evidence of non-local transport. This work shows that the steady state profiles, the cold-pulse rise time and disappearance at higher density as measured in these experiments are successfullydoi:10.1103/physrevlett.120.075001 pmid:29542943 fatcat:kya3vjfdzzcfxbofoer6piu5zy
