As MgB2 is a new alternative superconducting strand for CIC conductor,the technology of cabling is important.As we know,the damage to the strand would happen during the cabling process,and the main kind of damage is the indentation on the cross section,caused by the adjacent strands.In this paper,the artificially indentations on the performance of MgB2 round wire will be studied.In the experiment,the MgB2 samples will be marked with various depths artificially before heat treated.Then,the performances such as critical current,n-value,residual resistance ratio and AC losses will be measured.The influence of indentation will be observed and discussed according to the experiment results.
