Abstract We intend to carry out a first exploraory survey of the redshifted Lyman continuum spectra of high redshift quasars. The main objective is to investigate the opacity of the intergalactic medium in the Lyman continuum and to carry out the He+ equivalent of the Gunn-Peterson test for once ionized intergalactic helium. ------------------------------------------------------------------------------------ 8.

Chris Blades ESA, SPACE TELESCOPE SCIENCE USA X INSTITUTE Francesco Paresce ESA, SPACE TELESCOPE SCIENCE USA X INSTITUTE ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The objective prism mode of the FOC is the fastest and operationally simplest far-ultraviolet spectroscopic mode available onboard ST. Hence it is ideally suited to carry out a first exploratory survey of the redshift Lyman continuum spectra of the highest redshift quasars. ------------------------------------------------------------------------------------ 13. A first exploratory survey of the redshifted Lyman continuum spectra of the hghest redshift quasars will be carried out using the objective prism mode of the FOC. The main objective is to investigate the opacity of the intergalactic medium in the Lyman continuum and to carry out the He + equivalent of the Gunn-Peterson test. ------------------------------------------------------------------------------------ 11.
