## The TUS Detector of Extreme Energy Cosmic Rays on Board the Lomonosov Satellite

The origin and nature of extreme energy cosmic rays (EECRs), which have energies above the —the Greisen-Zatsepin-Kuzmin (GZK) energy limit, is one of the most interesting and complicated problems in modern cosmic-ray physics. Existing ground-based detectors have helped to obtain remarkable results in studying cosmic rays before and after the GZK limit, but have also produced some contradictions in our understanding of cosmic ray mass composition. Moreover, each of these detectors covers only a part of the celestial sphere, which poses problems for studying the arrival directions of EECRs and identifying their sources. As a new generation of EECR space detectors, TUS (Tracking Ultraviolet Set-up), KLYPVE and JEM-EUSO, are intended to study the most energetic cosmic-ray particles, providing larger, uniform exposures of the entire celestial sphere. The TUS detector, launched on board the Lomonosov satellite on April 28, 2016 from Vostochny Cosmodrome in Russia, is the first of these. It employs a single-mirror optical system and a photomultiplier tube matrix as a photo-detector and will test the fluorescent method of measuring EECRs from space. Utilizing the Earth’s atmosphere as a huge calorimeter, it is expected to detect EECRs with energies above ${}^{}$.

It will also be able to register slower atmospheric transient events: atmospheric fluorescence in electrical discharges of various types including precipitating electrons escaping the magnetosphere and from the radiation of meteors passing through the atmosphere. We describe the design of the TUS detector and present results of different ground-based tests and simulations.

International symposium on Ultra-High-Energy Cosmic Rays, UHECR2018

12.10.2018

This UHECR workshop will cover recent results from UHECR observations and theoretical developments as well as future plans.  The symposium will focus on the highest energy cosmic rays as well as cosmic rays at lower energies above 1 PeV, and on multi-messenger approaches.
Review talks by invited speakers and contributions including posters will be presented by experimentalists and theorists in plenary sessions.

UHECR 2018 will take place in the heart of Paris, at “Chimie Paris Tech” Campus (formerly know as the "Ecole Nationale de Chimie Supérieure de Paris ").

Event information is already available on the conference website at
