“…where A is the mean value of ADC counts A, and RMS(A) is the root mean square of A. The energy threshold for TUS was determined to be approximately 70 EeV during moonless nights, and the instrument should be able to register several EECRs above the threshold in 5 years of continuous operation [26] assuming the energy spectrum obtained with the Pierre Auger Observatory for highly inclined EAS [28]. The energy threshold only weakly depends on the value of adjacency length employed in the second level trigger [26].…”

Abstract. TUS (Tracking Ultraviolet Set-up), the first orbital detector of extreme energy cosmic rays (EECRs), those with energies above 50 EeV, was launched into orbit on April 28, 2016, as a part of the Lomonosov satellite scientific payload. The main aim of the mission is to test a technique of registering fluorescent and Cherenkov radiation of extensive air showers generated by EECRs in the atmosphere with a space telescope. We present preliminary results of its operation in a mode dedicated to registering extensive air showers in the period from August 16, 2016, to November 4, 2016. No EECRs have been conclusively identified in the data yet, but the diversity of ultraviolet emission in the atmosphere was found to be unexpectedly rich. We discuss typical examples of data obtained with TUS and their possible origin. The data is important for obtaining more accurate estimates of the nocturnal ultraviolet glow of the atmosphere, necessary for successful development of more advanced orbital EECR detectors including those of the KLYPVE (K-EUSO) and JEM-EUSO missions.

“…Various simulations were performed for TUS before the launch, and the energy threshold for effective registering of EECRs was determined to be approximately 70 EeV, so that the instrument should be able to register several events above the threshold in 5 years of continuous operation assuming the energy spectrum obtained with Auger for highly inclined EAS [19]. In what follows, we only discuss results obtained in the EAS mode.…”

TUS is the world's first orbital detector of extreme energy cosmic rays (EECRs), which operates as a part of the scientific payload of the Lomonosov satellite since May 19, 2016. TUS employs the nocturnal atmosphere of the Earth to register ultraviolet (UV) fluorescence and Cherenkov radiation from extensive air showers generated by EECRs as well as UV radiation from lightning strikes and transient luminous events, micro-meteors and space debris. The first months of its operation in orbit have demonstrated an unexpectedly rich variety of UV radiation in the atmosphere. We briefly review the design of TUS and present a few examples of events recorded in a mode dedicated to registering EECRs.

“…The total exposure is approximately 530 km 2 ·yr·sr. It is small in comparison with that of the largest ground-based arrays but sufficient to look for an EECR above the TUS threshold energy E 70 EeV [21].…”

“…The general design of TUS is determined by its main task of registering fluorescence and scattered (reflected) Cherenkov radiation of EASs in the near UV band with a time resolution of 0.8 µs in full temporal interval of 256 time steps. TUS has a two-level trigger [20,21]. The first-level trigger is a threshold one: the PDM board calculates a moving sum (MS) of PMT signals during 16 consecutive time steps in each channel and looks for an MS value above a threshold level (active pixel).…”

For the Lomonosov-UHECR/TLE CollaborationTUS (Tracking Ultraviolet Set-up) is the first orbital detector of extreme energy cosmic rays. It was launched into orbit on April 28, 2016, as a part of the scientific payload of the Lomonosov satellite. The main aim of the mission is to test the technique of measuring UV fluorescent and Cherenkov radiation of extensive air showers (EAS) generated by primary cosmic rays with energies above 50 EeV. The first year of operation has revealed an unexpectedly rich diversity of UV radiation. Among different types of registered events, we have identified those caused by thunderstorm activity and transient luminous events (TLEs), anthropogenic factors and by lowenergy cosmic rays passing through the UV glass filters covering the focal plane. Three modes of operation aimed at studying TLEs and meteors were also tested. A search and analyses of EAS candidates is in progress. We report the preliminary results obtained during the first year of TUS operating in orbit in all modes of operation with a special attention to the EAS mode.
