Mambo Bolometers at IRAM-30m

Description

The Mambo-1 and Mambo-2 bolometers have been developed at the Max-Planck-Institut fur Radiostronomie in Bonn by the group of Ernst Kreysa: MAMBO's 37 channel array has been successfully used by many observers since the end of 1998. Winter 2001/2002 was the first season of the new MAMBO-2 version with 117 pixels. The 37 channel MAMBO is used at the 30 m telescope as a backup system now. Both systems work at 1.2 mm wavelength and have a He-3 fridge to operate the bolometers at a temperature of 300 mK.

Status

He-Refilling

When in use, Mambo1 or Mambo2 are currently refilled with He4 every 48 hours. This procedure takes about 4-5 hours. It can be used for heterodyne observations.

Data Reduction

The data from the bolometer observations are recorded in IMBfits format. The data can be reduced using the Mopsic program (<zylka@iram.fr>) which is part of the GILDAS package.
