The Sunyaev Zel ’ dovich effect ( SZ effect ) is a complete probe of ionized baryons , the majority of which are likely hiding in the intergalactic medium .
We ran a 512 ^ { 3 } \Lambda CDM simulation using a moving mesh hydro code to compute the statistics of the thermal and kinetic SZ effect such as the power spectra and measures of non-Gaussianity .
The thermal SZ power spectrum has a very broad peak at multipole l \sim 2000 - 10 ^ { 4 } with temperature fluctuations \Delta T \sim 15 \mu K. The power spectrum is consistent with available observations and suggests a high \sigma _ { 8 } \simeq 1.0 and a possible role of non-gravitational heating .
The non-Gaussianity is significant and increases the cosmic variance of the power spectrum by a factor of \sim 5 for l < 6000 .

We explore optimal driftscan survey strategies for the AMIBA CMB interferometer and their dependence on cosmology .
For SZ power spectrum estimation , we find that the optimal sky coverage for a 1000 hours of integration time is several hundred square degrees .
One achieves an accuracy better than 40 \% in the SZ measurement of power spectrum and an accuracy better than 20 \% in the cross correlation with Sloan galaxies for 2000 < l < 5000 .
For cluster searches , the optimal scan rate is around 280 hours per square degree with a cluster detection rate 1 every 7 hours , allowing for a false positive rate of 20 \% and better than 30 \% accuracy in the cluster SZ distribution function measurement .
