The Low Energy Transmission Grating Spectrometer (LETGS) on board CHANDRA (AXAF)

    Press releases (Dutch only)

    The Advanced X-ray Astrophysics Facility (AXAF, recently renamed CHANDRA) is the third observatory in the series of Great Observatories in the NASA programme after the Hubble Space Telescope and the Compton Gamma-Ray Observatory. CHANDRA is planned for launch in July 1999. CHANDRA contains a Wolter-Type I high-resolution telescope, two insertable gratings, the Low-Energy Transmission Grating (LETG) and the High-Energy Transmission Grating (HETG) as well as two imaging detector systems. The LETG is being developed by SRON in cooperation with the Max Planck Institute fuer Extraterrestrische Physik (MPE) in Garching. 

    A good starting point for learning about AXAF and how to use it is the homepage of the CHANDRA X-ray Center (CXC)
