TL;DR
The JEM-EUSO mission aims to study the origins and physics of extreme energy cosmic rays using a space-based telescope to detect UV photons from air showers, potentially revealing their sources and fundamental physics insights.
Contribution
This paper introduces the JEM-EUSO mission, a novel space-based observatory designed to detect ultra-high-energy cosmic rays with unprecedented exposure and resolution.
Findings
Designed to achieve over 1 million km^2 sr year exposure
Will map arrival directions of over 500 EECR events
Aims to identify cosmic ray sources and test fundamental physics
Abstract
The JEM-EUSO mission explores the origin of the extreme energy cosmic rays (EECRs) above 100 EeV and explores the limits of the fundamental physics through the observations of their arrival directions and energies. It is designed to achieve an exposure larger than 1 million km^2 sr year to open a new particle astronomy channel. This super-wide-field (60 degrees) telescope with a diameter of about 2.5 m looks down from space onto the night sky to detect near UV photons (330-400nm, both fluorescent and Cherenkov photons) emitted from the giant air showers produced by EECRs. The arrival direction map with more than five hundred events will tell us the origin of the EECRs and allow us to identify the nearest EECR sources with known astronomical objects. It will allow them to be examined in other astronomical channels. This is likely to lead to an understanding of the acceleration…
