Description

The accident in J-PARC hadron experimental hall was triggered by the target damage due to an unanticipated short beam pulse from J-PARC main ring. The short beam pulse was generated by the rapid current increase, which was caused by malfunction of a spill feedback quadrupole (EQ) power supply system. The simulation with the slow extraction process can explain the short beam pulse generation. An investigation for the malfunction of the EQ power supply system is under way. We have considered measures to prevent recurrence. (author)
