Web site for the EUSO-Ballon project

BALLOON-EUSO is a partnership project of the international consortium JEM-EUSO and CNES that aims to fly over several campaigns in 2013, a prototype fluorescence telescope aboard a stratospheric balloon CNES.
The objective of this type of mission is to test the validity of concepts and technical choices made today for the JEM-EUSO space mission scheduled for 2017 or any subsequent project aimed at achieving an observatory of giant air showers induced by energetic cosmic rays from space.
The design and the construction of this telescope is a real technical challenge, as it involves the use of new technologies from the laboratories of both industrial and research laboratories in areas as diverse as optical large and accurate Fresnel lenses, a technique of photodetection highly sensitivive and good resolution, and very innovative analog and digital electronics.
The aim of the project EUSO-BALLOON is threefold:

  • Test all the technologies developed for JEM-EUSO under very severe operating conditions(stratosphere), partly representative of some conditions that would have to meet any telescope fluorescence light space (accomodated on the ISS or in free flight on a satellite),
  • To measure the intensity of the atmospheric airglow with an appropriate angular resolution for JEM-EUSO, this continuous background requiring to be subtracted to any measured signal,
  • To highlight the ability of such an instrument to detect air showers from space (above the measured background level from the Airglow).

Now the JEM-EUSO Team is working in a developpement Phase B.

The information is centered on this web site for a better circulation of the information among the participant to the project.

People involved in that developpement have to log-in to access to the Project EUSO-Balloon section of this web site.
