Engineering and Developmental Projects- completed •East-Asia Front End Integration Center•22 (out of 69) Front End Assemblies delivered by EA-FEIC•

Two Front End Service Vehicles delivered in 2011

•Nutator Development

Engineering and Developmental Projects- in progress ••Band 1 Receivers (30 - 50 (52) GHz)•in collaboration with NAOJ, NRAO, HIA, and Univ. of Chile.

•Approved officially by ALMA board in mid 2016•

1st prototype tested at site in 2017 spring•

1st cartridge delivered to site in mid-2017•

Production of 73 cartridges completed by end of 2019

Multi-Pixel Receiver at 1.5 THz band

ASIAA CASA Development Center•

ASIAA CASA Development Center (ACDC)•

established on 2016 August 1st.

•in collaboration with NRAO, with the funds of the Ministry ofScience and Technology (MoST)•Chin-Fei Lee is the ACDC manager••

Currently 4 full time staffs work for ACDC, including two software
engineers, one system manager, and one support scientist.

•The number of software engineers is expected to increase to 5 in 2019

ASIAA CASA Development Center•

Technical Work Areas•

Development at the ACDC will be fully integrated and coordinated with
the CASA team.

•For the initial year, the ASIAA team will augment the effort of NRAO on
the next generation CASA image viewer; CARTA (Cube Analysis andRendering Tool for Astronomy).

••

expected to deliver core features in the first year time scale, andenhanced features (e.g., PV diagrams, 3D rendering) in the 2nd yeartime scale.

•The goal is to replace CASA viewer in CASA.

During the second year (depending on our CARTA progress andhiring), the ASIAA center will add a component of highperformance computing (HPC) to the development targets.

Taiwan ARC Node•established in November 2009, connecting to EA ARC and NA ARC•working with EA ARC for user support core functions (i.e., P2G,QA2, CS, Helpdesk, TA, AoD)•

working with NA for enhanced functions•

currently 9 ARC members•organizing workshops / tutorials on-island in Taiwan, togetherwith universities in Taiwan
