Cool (C II and Si IV) and hot (Fe XVIII) components of jets. The SJI C II 1330 Å (top panel), Si IV 1400 Å (middle panel) and the Fe XVIII images (bottom panel) (reverse colour) during the recurrent jet activity. The black arrows (second column from the left) indicate the small loop-like structure inside the foopoint region of the jet. The third column sampled jet 2, the fourth to sixth column sampled jet 4.
