ALMA Band 2 covers 65 GHz to about 90 GHz (3.3 - 4.6 mm wavelength). This workshop is to discuss and develop the science case for Band 2 in preparation for the future funding of the design and development of receivers for this band.

In developing the science case there are two important considerations in addition to the new frequency range band 2 would make accessible with ALMA. First, the enhanced science possible if a single receiver could be developed to simultaneously cover from 65 GHz to 116 GHz, encompassing both  bands 2 and 3.  Second, the possibility of having a 16 GHz instantaneous bandwidth.

The aim of the workshop is

• to assess the science which Band 2 and a Band 2+3 system enable
• to identify a number of top-level science cases,
• to identify  the impact Band 2 can have across the full range of ALMA science areas.

This workshop is part of an ESO funded ALMA development project looking at the science case and  technical requirements for ALMA Band 2. There is no registration fee for the workshop and some funds are available to partially support some participants.
