1. Status of the Korean ALMA project Jongsoo Kim Korea Astronomy and Space Science Institute

2. ALMA activities before 2014 in Korea 2012-03-19 –MOU bew. NAOJ and KASI 2012-09-13,14 –ALMA EA Science Workshop 2012, 2013 –Reports of Planning Study for the ALMA project were submitted to the KASI –Last December, a report was finally approved in the KASI

3. Preparation of Cycle 2 CfP Survey Science Group, KIAS –2013-10-04, Cycle 2 CfP Town Meeting at KASI –2013-10-28, 64 participants –Cycle 2 Capability, OT, CASA Simulator SNU Colloquium –2013-11-21, Cycle 2 CfP ALMA proposals from Korea: 17

4. Classification of 17 proposals Fields –Cosmology and the high redshift Universe: 2 –Galaxies and galactic nuclei: 2 –Interstellar medium, star formation and astrochemistry: 11 –Circumstellar disks, exoplanets and the Solar System: 1 –Stellar evolution and the Sun: 1 Institutions –KASI: Universities = 12:5

5. ALMA Korean Project ARC: Jongsoo Kim, A-Ran Lyo, Ji-Hyun Kang, Kyung-Hee Kim, Chandreyee Sengupta Development: Jungwon Lee, Do-Hung Je, Ji-Man Kang, Seung-Lae Kim

6. ALMA Korean Project budget: 15MUSD/11years + 20MUSD (2020~2023years) ARC –Proposals, observing scripts, reductions, sciences Development plan –Multi-Beam Receivers (ASTE  ALMA TP) –Spectrometer/Correlator (ASTE  ALMA TP)

7. Multi-beam Receiver for ASTE Frequency band: 345 GHz or 460 GHz (or wide band to cover both bands) Number of beams: 9~64 beams RF/IF Specifications: follow the ALMA specification (except polarization)

8. Software Spectrometer for an ASTE Multi-beam Receiver goal specification for a multi-beam receiver (ALMA specification): 4 basebands with 2GHz bandwidth, dual polarisation, 16 beams performance requirement: ~ 20 Tflops input and output data rates: 1.6Tb/s, 200MB/sec A software spectrometer based on a 16-node cluster with 64 40GE ports and 32 GPU cards is proposed.

9. 2-band quasi-optics for ASTE Simultaneous observations using two receivers –CATS345, 324-372 GHz –ALMA B8QM, 400-500GHz Need modifications of the current spectrometers, –MAC –WHSF
