The Boomerang North America instrument: a balloon-borne bolometric radiometer optimized for measurements of cosmic background radiation anisotropies from 0.3 • to 4 •. ABSTRACT We describe the Boomerang North America (BNA) instrument, a balloon-borne bolometric radiometer designed to map the Cosmic Microwave Background (CMB) radiation with 0.3 • resolution(More)
We report the design and performance of 300-mK composite bolometers that use micromesh absorbers and support structures patterned from thin films of low-stress silicon nitride. The small geometrical filling factor of the micromesh absorber provides 20x reduction in heat capacity and cosmic ray cross section relative to a solid absorber with no loss in(More)
This study focuses on the connections between young people's everyday experiences with video games and social networks, and the formal high school curriculum. We assume that digital literacy combines elements of traditional literacy and media education with other dimensions founded on the idea of a participatory culture. The research has been designed from(More)
