  We present accurate measurements of carrier-envelope phase effects on
ionisation of the noble gases with few-cycle laser pulses. The experimental
apparatus is calibrated by using atomic hydrogen data to remove any systematic
offsets and thereby obtain accurate CEP data on other generally used noble
gases such as Ar, Kr and Xe. Experimental results for H are well supported by
exact TDSE theoretical simulations however significant differences are observed
in case of noble gases.
