Call for Proposal (2018-2019 term)

 We would like to call for proposals using TRAO (Taeduk Radio Astronomy Observatory) 14m telescope for the term of 2018 autumn to 2019 spring. Recently we successfully installed a multi-beam receiver system, SEQUOIA-TRAO, and renovated most part of the telescope system. The new receiver system is now equipped with high-performing 16-pixel MMIC preamplifiers in a 4x4 array, operating within 85-115.6 GHz frequency range. System temperature ranges from 170 K (86~110 GHz) to 400 K (115 GHz; 12CO). The 2nd IF modules with the narrow band and the 8 channels with 4 FFT spectrometers allow to observe 2 frequencies simultaneously within the 85~100 or 100~115 GHz bands for all 16 pixels of the receiver. OTF (On-The-Fly) mapping mode is the main observing mode, and a simple position switching mode is also available. OTF test observation shows that it takes 27 min for 6’x6’ region, and 37 min for 10’x10’. You may decide a regrid size and convolution parameter after completion of your observation. Pointing accuracy is about 6 acrsec. The backend system (FFT spectrometer) provides the 4096x2 channels with a fine velocity resolution of better than 0.05 km/s (15 kHz) per channel. Its effective spectra bandwidth is 60 MHz.
 There are three Key Science Programs (KSP) running for three years, abstracts of which are accessible at the TRAO home page.  Proposals which are not overlapped with KSPs are encouraged. Please refer the TRAO homepage for KSPs and other information.  There are lots of telescope time avaliable between LST 10 and 15hrs, thus proposals using this time slots would have more privilege.  Scientists, who did not have an observing experience at TRAO, are encouraged to have an internal collaborator(s) of KASI (Korea Astronomy and Space Science). The upper limit of telescope time per proposal is suggested as 100 hours. Two bedrooms and kitchen are available for outside observers. Deadline for proposal submission is August 31st  2018 (KST 23:59; UT+9).
