摘　　要：The runaway electron phenomenon caused by dis- ruptions is one of the challenging conditions on the ITER Tokamak, which may destroy the vacuum ves- sel. To avoid runaway electrons hitting the fist wall, there must be some monitor systems which can pro- vide position information of the runaway electron beam. Hard x-ray camera is the most conventional di- agnostic system to monitor the runaway electrons. While there is no hard x-ray camera working for the entire ITER operation phase even for D-D phase of ITER, there must be some systems playing the role of observation of the runaway electrons. In this case, with some international experiences from other Toka- mak devices, the soft x-ray camera can share the role of runaway electron observation. On JET and some other Tokamak devices, the runaway electron current generated by disruption has been observed by the soft x-ray camera system.The runaway electron phenomenon caused by dis- ruptions is one of the challenging conditions on the ITER Tokamak, which may destroy the vacuum ves- sel.
