Abstract
The expected polarized component of the CMB signal is extremely faint. On degree angular scales and above it can be in the range of one part to 106 or 107. To detect such an elusive signal a dedicated instrument must be designed. In this contribution we present the new Milano polarimeter, a 33 GHz correlation system able to detect both linear and circular polarization. It has been designed to operate at large angular scale (7° — 14°) from the ground. In the light of the last observing campaign conducted from Antarctica we have partially redesigned the radiometer to improve its long term stability and sensitivity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
