Abstract: We describe the PIPER balloon born instrument for observing the polarization of the cosmic microwave background. The experiment uses two co-aligned cold optic telescopes with variable-delay polarization modulators as their first optical element. Each telescope has two 32 x 40 arrays of backshort-under-grid(BUG) TES bolometers
