We describe a new ground based telescope dedicated to millimetre cosmo
logical research: MITO, Millimetre and Infrared Testagrigia Observator
y. The site and all the instrumental subsystems of the telescope have
been chosen to perform high sensitivity measurements for wavelengths r
anging from 300 micron to 2 millimetre. The possibility of detecting f
luctuations of the Cosmic Microwave Background has been explored for s
ome observational strategies.
