Status of the Korean ALMA project JongsooKim Korea Astronomy and Space Science Institute
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
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
Classification of 17 proposals • Fields • Cosmology and the high redshift Universe:2 • Galaxies and galactic nuclei: 2 • Interstellar medium, star formation and astrochemistry: 11 • Circumstellardisks, exoplanets and the Solar System: 1 • Stellar evolution and the Sun: 1 • Institutions • KASI: Universities = 12:5
ALMA Korean Project ARC: Jongsoo Kim, A-Ran Lyo, Ji-Hyun Kang, Kyung-Hee Kim, ChandreyeeSengupta Development: Jungwon Lee, Do-Hung Je, Ji-Man Kang, Seung-LaeKim
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)
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)
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.
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
