  19. Difficulties We Met …… • However, there is a new regulation in Taiwan that the mountain area above 1500 m was assigned as protected area and only limit buildings are allowed. Astronomical observatory was not included. • Thank to assistant from Chairman Wang of Legislative Yuan to coordinate government ministries, astronomical observatory was finally put into the list in late 2007. • The building permit was issued on 11/15/2008 from Chiyi county government. • A local company won the contract for the building and was ready to start the construction in May 2009 …… 2011兩岸天文儀器會議

  20. Difficulties We Met …… • In May 2009, Environment Protection Administration (EPA) informed us the construction must be suspended because the 2M building is located inside an animal protection area. • Environmental impact assessment must be done in advanced. • In this animal protection area, four season’s animal inspection is essential. • The building permit was invalid • The building contract had to be rescinded • Environmental impact assessment was made from Oct 2009 to Nov 2010 and the report was approved by EPA in March 2011. The new budget was set and the construction will be started soon. 2011兩岸天文儀器會議

  21. Instrument 2011兩岸天文儀器會議

  22. Instrument • The first generation instrument for 2M telescope is the Simultaneous Multi-color Imager. • This 4-color simultaneous imager consists of • Dichroic mirrors and filters • split the light into 4 bands: 552-689nm(r), 691-815nm(i), 815-915nm(z) and 967-1024nm(y) • higher QE CCD cameras • 3 sets of 1100-series cameras were purchased from Spectral Instruments Inc.,USA, within E2V back illuminated deep depletion CCDs for r,i,z bands • The other one (NCU-Cam1), with within fully depleted CCDfrom Hamamatsu photonics K.K., Japan. and Polycold cryo-cooler, is developed by NCU instrument team 2011兩岸天文儀器會議

  23. 4-color Simultaneous Imager 2011兩岸天文儀器會議

  25. Instrument Lab at NCU • To make the multi-color imager for 2M telescope, as well as for future instrument developments, NCU set up an instrument lab in early 2009. • Key persons of NCU lab • Jason Wu: Electrical engineer • Duncun Chen: Project assistant • Azure Yang: Project assistant 2011兩岸天文儀器會議

  33. Summary • The manufacture of telescope has been completed and the telescope has shipped to Taiwan in 2010. • The environment impact assessment has been completed and the new budget has set. The construction will be started soon/ • The 4 cameras, including the one we develop (NCUcam1), and the optical system for the 4-color simultaneous imager have been complete. The integration test cannot be done due to the delay of telescope dome construction. • We are now looking for suitable telescope that allows us to test instrument’s performance, or, furthermore, start scientific observations. 2011兩岸天文儀器會議
