Scope of this meeting:
The ALMA Development Roadmap has identified the multiplication of the IF bandwidth of ALMA (at least by a factor 2) as one of the main priorities for ALMA upgrades in the 2020s. This increase of the instantaneous bandwidth will be realized with the coordinated upgrade of receivers in the Front End, the correlators, and last but not least, all electronics between them: digitizers, backend and Data Transmission System (DTS). This meeting aims to bring together experts on the ALMA system and digitizer, backend and data transmission system technologies, from within ALMA and from the community, in order to:

(1) discuss the status of technology and performance prospects for the next decade for digitizers, backend and DTS,

(2) identify the impact on these subsystems due to the increase of the instantaneous bandwidth by a factor >2, 

(3) discuss the most suitable location of the 2nd generation ALMA correlators in relation with the status of DTS technologies,

(4) identify the possibility to use off-the-self technologies for the implementation of the 2nd generation of ALMA digitizers, backend and DTS, 

(5) discuss on possible system architectures to implement the multiplication of the IF bandwidth of ALMA by a factor >2.

We particularly encourage participation by young scientists, and we have a modest amount of travel support.
