Scientific paper

We request 15ks exposure of the luminous quasar Ton 34. The UV spectra shows an extreme UV break near 1100 A and the tail of a possible flux recovery towards the X-rays. This UV-deprived unique AGN may well hold the key to the origin of the UV break present in luminous quasars. The X-ray observations would serve to put constraint on the SED behavior in the extreme UV and on how the UV might connect with the soft X-rays. A secondary continuum peak is required to occur in the soft X-rays, if photoionization theory of quasars is to be saved. The presence of cold or warm gas of NH ~5-E21 cm-2 is expected if crystalline dust grains were the cause of the UV break. Such columns are detectable with the proposed programme, allowing to confirm or discard the crystalline dust scenario.
