摘要： The foil-excited the spectrum of highly stripped titanium ions between 12--40~nm has been studied. Titanium ions of 80 and 120~MeV were provided by the HI-13 tandem accelerator at the China Institute of Atomic Energy. GIM-957 XUV-VUV monochromator was refocused to get highly-resolved spectra. Our experimental results and the published spectral data of laser-produced plasma show agreement in nearly all cases within \pm 0.03nm. The spectra contained some weak or strong lines previously unclassified. These spectral lines mainly belong to 2s2p^{2 } for TiXVIII, 2p^{3} for TiXVIII, 2s2p^{3} for TiXVII, 2p^{6}4p for Ti XII and 2p^{6}3d for Ti XII transitions.
