This is the public page for our part of the "ALMA Phasing Project" (APP) at MPIfR.
If you are looking for the "official" APP pages go here.
The APP project was presented By W. Alef at the "11th European VLBI Network Symposium & Users Meeting"
The presentation can be found here, the proceedings will soon become available here.
Summary of the APP project
By phasing all ALMA dishes together into a single effective aperture, ALMA can operate as both an exceptionally sensitive mm/sub-mm VLBI element and a beamformed array suitable for high frequency pulsar work. A detailed design for implementing a system to phase up the array has been completed and funding to build and integrate this capability into ALMA has been secured. With this system in place, ALMA will become a key element in Global mm/sub-mm VLBI arrays that target a broad range of high sensitivity and high angular resolution science.
APP status
The APP has passed both the preliminary design review and the critical design review and is being implemented.
First tests are planned for early 2014, the project will end with the commissioning pf the phasing system early 2015.
