X-Ray Telescope (XRT) Aboard Hinode: Key Instrumental Features and Scientific Highlights

Chapter
Part of the Astrophysics and Space Science Library book series (ASSL, volume 449)

Abstract

The X-ray Telescope (XRT) aboard Hinode was designed to observe the solar corona in its entire temperature range, spanning from below 1 million Kelvin (MK) to beyond 20 MK. In particular, the capability of observing low-temperature (below 2 MK) plasmas that were not accessible with the Yohkoh Soft X-ray Telescope (SXT), coupled with an order of magnitude higher cadence than SXT, has enabled XRT to make various discoveries on coronal activities. Furthermore, XRT has the unique strength of observing high-temperature plasmas in the corona that are not necessarily well observed with other coronal imagers. The scientific considerations made while designing the XRT and the key points of the instrumental features are reviewed, followed by some highlights of the scientific results obtained with XRT.

Hinode is a Japanese mission developed and launched by ISAS/JAXA, collaborating with NAOJ as a domestic partner and NASA and STFC (UK) as international partners. Scientific operation of the Hinode mission is conducted by the Hinode science team organized at ISAS/JAXA. This team mainly consists of scientists from institutes in the partner countries. Support for the postlaunch operation is provided by JAXA and NAOJ (Japan), STFC (UK), NASA, ESA, and NSC (Norway).

In addition, throughout the development and operation stage of Hinode, indispensable support was given by engineering researchers of JAXA and by our industrial partners, which made XRT observations possible for these 10 years with the expected observational performance. I hereby express my sincere gratitude and would appreciate continuous support to the Hinode mission.
