European Development Studies

In order to keep ALMA at the forefront of technology, ESO invites its member state institutes to participate in the European ALMA development programme. Every three years, ESO issues a call for development studies. Below, we provide an overview of the studies approved in 2010, 2013, 2016 and 2019.

ALMA Development studies aim at informing and developing technologies to implement the long term ALMA Development Roadmap. The majority of studies since 2016 are focused on the themes identified in the ALMA 2030 Reports.

The North American ALMA partner has a similar development study programme. The overview of these studies can be found here: NRAO Studies.

In addition to the external studies, ESO also runs several small internal development studies which require inside knowledge of the ALMA systems. These generally use only limited FTE and are supported financially only for a small travel budget.
