RECOMMENDATIONS

The sections above describe the science drivers and the required polarization performance of the ALMA. Specific recommendations have been discussed in section 4. However, millimeter-wave polarimetry is not yet a mature field. We therefore strongly recommend that the systems for polarization observations with the ALMA be implemented and tested at the earliest possible time. Use of existing millimeter-wave interferometers is likely to be useful, but implementation of polarization capabilities from the beginning on the first ALMA test interferometer is essential if the ALMA is to fulfill its promise for polarization.
