LSPE Project (Large Scale Polarization Explorer)

LSPE is a stratospheric balloon mission funded by ASI, dedicated to measuring the polarization of the cosmic microwave background radiation (CMB) on large angular scales. The objective is to achieve a high sensitivity thanks to the use of mosaics of detectors of new concept, by exploiting the possibility to perform circumpolar long duration flights over the Arctic night.

The spacecraft will host two instruments: a high frequency, SWIPE, a mosaic of three-channel bolometers (100, 150 and 220 GHz) under the responsibility of the University of Rome La Sapienza and STRIP, a coherent low-frequency instrument, an array of polarimeters at 40 GHz with an additional channel at 90 GHz with a limited sensitivity, mainly used for the control of systematic errors. This frequency coverage will allow to observe and remove the emissions of the foreground, from the dust (high frequency) to the synchrotron and free-free (low frequency). Once built, STRIP will be the most sensitive and complex mosaic of coherent polarimeters ever developed for a flight science.

INAF is involved in the development of low-frequency instrument STRIP in collaboration with the Universities of Milan (Bicocca and State), the IEIIT-CNR of Torino and the University of Trieste. The structure INAF-Observatory of Trieste has the responsibility for the design and implementation of the data acquisition system, of the EGSE (Electrical Ground Support Equipment) and of the on-board software.
