Abstract
The measurements of the ultraviolet response by some UV-enhanced CCDs have been realized. In particular, the quantum efficiency of coronene- and lumigen-coated and of back- illuminated ion-implanted CCDs have been measured in the 300 to 2500-angstroms spectral range. Very interesting performances have been found, mainly for one ion-implanted CCD with quantum efficiency values of more than 60% at 304 angstroms. Also some measurements of the CCD uniformity response and spatial resolution capability in this spectral region have been performed. The obtained results are very promising for the possibility of using these semiconductor detectors in the ultraviolet spectral region also with very good performance.
