This paper reports the laboratory measurements of extreme ultraviolet spectra of highly charged copper ions. In this work, 82 lines from Cu xv to Cu xxiii in the 160–360 Å wavelength range are identified as the transitions of the 2p{sup 2}3p–2p{sup 2}3d, 2p{sup 4}3s–2p{sup 4}3p, 2p{sup 4}3p–2p{sup 4}3d, 2p{sup 5}3s–2p{sup 5}3p, 2p{sup 5}3s–2p{sup 5}3p, 3s3p–3p{sup 2}, 3s{sup 2}3p{sup 3}-3s3p{sup 4}, 3s{sup 2}3p–3s3p{sup 2}, 3s{sup 2}3p{sup 3}–3s3p{sup 4}, and 2p{sup 4} ({sup 3}P)3s–2p{sup 4} ({sup 3}P) 3p, in which 40 spectral lines have been newly and accurately measured. Their identification is based on comparisons with available experimental and theoretical values and the calculations with Cowan codes.
