Studies of the energy deposition by plasma jets incident on a material surface are of topical interest for both the fusion and plasma technology applications. In this paper the results are reported of a comparative study of plasma energy deposition on different material surfaces exposed to plasma jets of various duration and energy density, generated using the QSPA Kh-50 and the MPC devices. The spatial distribution of plasma energy density and the heat load on the surface were measured with a movable calorimeter. The measurements demonstrate that in the case of an exposure to QSPA plasma jets the absorbed heat load is approximately equal to 55-60% of the energy in the incident plasma jet. In the case of plasma jets generated using the MPC device the heat load on the target surface and was practically the same as for the QSPA jets, and additional shielding effects were found to be negligible due to the short duration of plasma jets.
