Description:

Advancements in CMB research has brought about not only a new age of precision cosmology, but also galactic astrophysics. WMAP has uncovered some tantalizing questions about the nature of dust emission in the galaxy, and has provided glimpses of a potentially new mechanism for energizing cosmic rays in the region around the center of the galaxy. The LATTE telescope has a single 9GHz receiver, Dicke switch radiometer operating at 30Hz, with a proven temperature uncertainty of under 10mK per switch cycle. The high sensitivity is due to a low noise cryogenic HEMT amplifier and a low loss cryogenic PIN diode switch. Using the optical design of the BEAST experiment, LATTE maps the microwave sky with an angular resolution of ∼ 1.5° degrees covering about half the sky in one 24 hour period. In this document the expected and actual performance are reviewed, and preliminary pseudo-maps are presented.
