Solar Eclipse Pictured by e2v Image Sensors Onboard JAXA Hinode Satellite

e2v image sensors helped capture images of a solar eclipse which occurred on the 14th of November, 2012. e2v provides technology for high performance systems and equipment used in medical science, aerospace, defense and industrial markets. The image sensors were installed on board JAXA’s Hinode Satellite.
JAXA is the Japanese Aerospace Exploration Agency, and its Hinode satellite captured an image of the moon travelling across the front of the Sun. Hinode was launched in 2006 and was formerly known as Solar-B.
Hinode is on a mission to explore the magnetic fields of the Sun. The data collected from the Sun’s magnetic field will help scientists study explosive solar activity and decipher how it can affect satellite communications and electric power transmission grids on Earth, explained officials.
Taro Sakao, Hinode Project Manager for ISAS/JAXA said, “I am very pleased to see the XRT image sensors from e2v continuing to operate perfectly after over 6 years in orbit and delivering such fine x-ray pictures of the solar corona.”
The three science instruments on board Hinode, namely the Solar Optical Telescope (SOT), X-ray Telescope (XRT) and the Extreme Ultraviolet Imaging Spectrometer (EIS) featured the e2v Charge Coupled Device (CCD) image sensors. The sensors are based on e2v’s CCD42 range suitable for space missions.
“The successful delivery of the CCDs and their excellent flight performance was made possible because of the close collaboration between e2v and the Solar-B project team over a period of nearly 20 years. I look forward to e2v’s scientific CCDs aboard Hinode continuing to provide high-quality scientific data and helping us to further understand the physics of the Sun,” Sakao added.
Jon Kemp, marketing and applications manager at e2v said, “e2v is proud to have supplied the image sensors used by all three instruments on JAXA’s Hinode mission. As well as capturing this amazing image of the recent solar eclipse, their findings help to increase our understanding of our Sun and its impact on our world.”
In December 2012 e2v aerospace and defense, Inc. announced the completion and shipping of production units of the first device in the Maxim Life Extension Program, the DG406AK/883B. This is the first in a series of products that will be qualified and re-introduced into the market to extend the life of a wide variety of Maxim ICs, which are used in an array of military and aerospace programs.
