2019 Korea JCMT User’s Workshop2019 June 3, KASI, Daejeon, Korea

• 논의 사항- 일본이 투자를 크게 줄임. 중국이 투자를 늘릴 예정이며 우리나라

도 조금 더 투자하는 것을 고려 중임- 국내 사용자를 늘리고 보다 적극적으로 활용할 필요가 있음.

Submm telescope!- 사용자를 지원하는 일종의 JCMT “townhall meeting” 필요- Large programs led by Korea researchers in the 3rd call?- JCMT Korea contact person: 권우진
