[55.04] MAXIMA 1 & 2: Observations of the Cosmic Microwave Background

B. Rabii (UC Berkeley, Space Sciences Laboratory, Lawrence Berkeley National Laboratory), MAXIMA Collaboration

We discuss the status of the data obtained from the first two flights of the MAXIMA balloon-borne experiment. We have recently released a measurement of the power spectrum of the Cosmic Microwave Background from l=36 to l=785 from the data of the first flight, MAXIMA-1. The second flight (MAXIMA-2) was launched in June, 1999. During five hours of Cosmic Microwave Background observation, we mapped a 225 square degree region of the sky with extremely low galactic dust contamination. Approximately 50 square degrees of this region overlap with the observations of MAXIMA-1. The combination of MAXIMA's beam size and scan strategy make it sensitive to CMB fluctuations on angular scales from 10 arcmin to 5 degrees. The instrument consists of an off-axis Gregorian telescope with a 1.3 m primary mirror and a receiver housing a 16 element bolometer array cooled to 100 mK. Observations were made at 3 frequency bands centered at 150, 240, and 410 GHz.

The MAXIMA experiment is supported by NASA though grants NAG5-4454 and NAG5-3941, and by the Center for Particle Astrophyiscs, a National Science and Technology Center operated by the University of California, Berkeley, under Cooperative Agreement No. AST 9120005.
