A key challenge to producing the fusion energy is preventing the runaway electrons that can bore holes in tokamaks. To see the electrons so that they can find ways to stop them before their population can grow into an avalanche an international team of researchers (USA – Princeton University, University of Wisconsin, Edgewood College, Japan, Switzerland) used a multi-energy pinhole camera which has the unique ability to record not only the properties of the plasma in time and space but its energy distribution as well. Use of the novel camera moves technology forward. Comparing their diagnosis to modeling will be the next step. A better understanding may lead to new mitigation techniques in the future…read more.
