We compare the intensity contrast at 630 nm, observed using the Spectro-Polarimeter (SP) aboard the Hinode satellite, with the 3D radiative MHD simulations of V¨ogler & Sch¨ussler (2007).
The intensity contrast of solar granulation: comparing Hinode SP results with MHD simulations
The good performance and low straylight level of the spectro-polarimeter (SP, Lites et al. 2001)and complete absence of atmospheric effects, enable a far more reliable determination of the granulation contrast at 630 nm, the wavelength at which the SP operates.
The intensity contrast of solar granulation: comparing Hinode SP results with MHD simulations
Spatial sampling: Since the data considered here are obtained using the spectro-polarimeter, we have to consider the sampling and integration effects of the slit and the CCD detector.

The overall polarimetry scheme at the ILC therefore combines the measurements of two Compton polarimeters, located upstream and downstream of the e+ e− interaction point, with data from the e+ e− annihilations themselves.
Improvements to the ILC Upstream Polarimeter
For optimized Compton polarimeters, a factor of two improvement over the SLD is expected.

Improvements to the ILC Upstream Polarimeter
Thus, the laser wire and polarimeter could only be operated on alternating bunches.
Improvements to the ILC Upstream Polarimeter
This approach seems promissing, especially since it doesn’t create additional backgrounds for the polarimeter.
Improvements to the ILC Upstream Polarimeter
The upstream polarimeter as it is forseen in the ILC RDR has several short comings, which make it impossible to reach the high precision goals.
