MAX CMB Research Results  

MAX Introduction

MAX measures CMB anisotropy on 0.5 degree angular scales. MAX has presented CMB results from nine sky regions from five flights from 1989 to 1994.



MAX Instrumentation

MAX is an off-axis Gregorian telescope and a bolometric photometer mounted on an attitude-controlled balloon platform. The telescope has a 1 m off-axis parabolic primary with an elliptical secondary which sinusoidally modulates the beam on the sky.

MAX Scanning Strategy and Observations

Each CMB observation (except MAX2 GUM) consists of constant velocity scans in azimuth while optically tracking a target star such that sky rotation pivots the observed area about the star. Stars used include:

Gamma Ursae Minoris (GUM)
Mu Pegasi
Sigma Herculis
Iota Draconis
Phi Herculis
