“…The situation can be improved using fast electronics to achieve a good precision on t i and for those showers with sufficient track length in the camera (over about 10 • ). This was first used by the HiRes collaboration with the HiRes-II detector ( (Abbasi et al, 2005a)). Alternatively the HiRes collaboration also developed a profile constrained time fit (PCF) for the part of its detector not equipped with fast electronic ((Abbasi et al, 2005a)).…”

This is a review of the most resent results from the investigation of the Ultrahigh Energy Cosmic Rays, particles of energy exceeding 10 18 eV. After a general introduction to the topic and a brief review of the lower energy cosmic rays and the detection methods, the two most recent experiments, the High Resolution Fly's Eye (HiRes) and the Southern Auger Observatory are described. We then concentrate on the results from these two experiments on the cosmic ray energy spectrum, the chemical composition of these cosmic rays and on the searches for their sources. We conclude with a brief analysis of the controversies in these results and the projects in development and construction that can help solve the remaining problems with these particles. CONTENTS

“…The fluorescence detectors (FDs) of the Auger [7], HiRes [8] and TA [9] experiments have a limited field of view (FOV) ranging from about 3 • to 30 • in elevation. This limited FOV introduces a detector bias depending on the shower geometry: For close by showers, the lack of a high elevation FOV prevents the observation of shallow showers and, therefore, deeper showers are favored in the event selection.…”

Abstract. We present a summary of the measurements of mass sensitive parameters at the highest cosmic ray energies done by several experiments. The X max distribution as a function of energy has been measured with fluorescence telescopes by the HiRes, TA and Auger experiments and with Cherenkov light detectors by Yakutsk. The X max or the average mass ( lnA ) has been also inferred using ground detectors, such as muon and water Cherenkov detectors. We discuss the different data analyses elaborated by each collaboration in order to extract the relevant information. Special attention is given to the different approaches used in the analysis of the data measured by fluorescence detectors in order to take into account detector biases. We present a careful analysis of the stability and performance of each analysis. The results of the different experiments will be compared and the discrepancies or agreements will be quantified.

“…First attempts by Japanese and US groups to detect fluorescence light from air showers were successful in the early 1970s [1]. This led to large scale experiments such as Fly's Eye [4] and HiRes [5] and eventually to the fluorescence detectors as part of the Pierre Auger Observatory [6] and the Telescope Array [7]. This technology shares a significant fraction in the successful measurements of ultra-high energy cosmic rays.…”

A compact and light-weight refractive telescope for the observation of extensive air showers

A : A general purpose instrument for imaging of Cherenkov light or fluorescence light emitted by extensive air showers is presented. Its refractive optics allows for a compact and lightweight design with a wide field-of-view of 12°. The optical system features a 0.5 m diameter Fresnel lens and a camera with 61 pixels composed of Winston cones and large-sized 6 × 6 mm 2 photo sensors. As photo sensors, semi conductor light sensors (SiPMs) are utilized. The camera provides a high photon detection efficiency together with robust operation. The enclosed optics permit operation in regions of harsh environmental conditions. The low price of the telescope allows the production of a large number of telescopes and the application of the instrument in various projects, such as FAMOUS for the Pierre Auger Observatory, HAWC's Eye for HAWC or IceAct for IceCube. In this paper the novel design of this telescope and first measurements are presented.
