Adding TDI mode to PRISM Li Zeng Advisor: Brian Taylor Jan.25, 2008

Outline  What is TDI mode?  72” Perkins Telescope and PRISM  Photon Transfer Curve of PRISM Read Noise, Gain, Full Well Capacity of PRISM  CCD images taken in TDI mode on Perkins: M77, M78, IC 434, NGC 2301  Acknowledgements

What is TDI mode?  Time Delay Integration on CCD  CCD reads out at the same speed the image of the sky sweeps on the focal plane of telescope Star Mirror CCD

72” Perkins Telescope and PRISM

M77 (Seyfert Galaxy)

M78 (Star forming Nebula)

IC 434 (Horsehead Nebula)

NGC 2301 (Open Cluster)
