JET's in-vessel magnetic diagnostics measured the plasma current (Ip) in four toroidally orthogonal cross-sections with 5 kHz sampling rate. Toroidal asymmetries of Ip during plasma Current Quench (CQ) on JET and the associated sideways displacement of the vessel have been described in the papers [1-3]. Here we present observations of toroidal asymmetry in the Ip spikes. The analysis of the toroidal asymmetry in the Ip spike was performed based on a large JET disruption database containing more than 6000 disruptions covered the period from 03/11/2005 until the end of JET operation. It was found that the toroidal asymmetry in Ip spike can reach ~ 30% relative to the magnitude of Ip spike in the major disruptions. The toroidal asymmetry of the Ip spike usually begins with the start of the spike, which is corresponds to the end of Thermal Quench (TQ), and ends at the moment when Ip reaches its maximum value. Since the first observation in 1962 on the TM-2 tokamak [4], the interpretation of both voltage and Ip spikes has been controversial. The toroidal asymmetry in the Ip spike may shed light on the nature of disruptions in tokamaks, in particular on the MHD modes responsible for tokamak disruptions in the final TQ phase, ultimately leading to CQ. It can be suggested that the Wall Touching Kink Mode (WTKM) [5] underlies the disruption and is responsible for both voltage and Ip spikes.
