This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of the fluorescence telescopes of the Pierre Auger Observatory is monitored with the optical relative calibration setup. Optical fibers distribute light pulses to three different diffuser groups within the optical system. The total charge per pulse is measured for each pixel and compared with reference calibration measurements. This allows monitoring the short and long term stability with respect of the relative timing between pixels and the relative gain for each pixel. The designs of the LED calibration unit (LCU) and of the Xenon flash lamp used for relative calibration, are described and their capabilities to monitor the stability of the telescope performances are studied. We report the analysis of relative calibration data recorded during 2004. Fluctuations in the relative calibration constants provide a measure of the stability of the FD.

This book was released on 2007 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absolute calibration of the Pierre Auger Observatory fluorescence detectors uses a 375 nm light source at the telescope aperture. This end-to-end technique accounts for the combined effects of all detector components in a single measurement. The relative response has been measured at wavelengths of 320, 337, 355, 380 and 405 nm, defining a spectral response curve which has been normalized to the absolute calibration. Before and after each night of data taking a relative calibration of the phototubes is performed. This relative calibration is used to track both short and long term changes in the detector's response. A cross check of the calibration in some phototubes is performed using an independent laser technique. Overall uncertainties, current results and future plans are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The aperture of the Fluorescence Detector (FD) of the Pierre Auger Observatory is evaluated from simulated events using different detector configurations: mono, stereo, 3-FD and 4-FD. The trigger efficiency has been modeled using shower profiles with ground impacts in the field of view of a single telescope and studying the trigger response (at the different levels) by that telescope and by its neighbors. In addition, analysis cuts imposed by event reconstruction have been applied. The hybrid aperture is then derived for the Auger final extension. Taking into account the actual Surface Detector (SD) array configuration and its trigger response, the aperture is also calculated for a typical configuration of the present phase.

Available in PDF, EPUB and Kindle. Book excerpt: It is generally felt in the cosmology and particle astrophysics community that we have just entered an era which later can only be looked back upon as a golden age. Thanks to the rapid technical development, with powerful new telescopes and other detectors taken into operation at an impressive rate, and the accompanying advancement of theoretical ideas, the picture of the past, present and future Universe is getting ever clearer. Some of the most exciting new findings and expected future developments are discussed in this invaluable volume. The topics covered include the physics of the early Universe and ultra-high energy processes. Emphasis is also put on neutrino physics and astrophysics, with the evidence for non-zero neutrino masses emerging from both solar neutrinos and atmospheric neutrinos covered in great depth. Another field with interesting new results concerns the basic cosmological parameters, where both traditional methods and the potential of new ones, like deep supernova surveys and acoustic peak detections in the cosmic microwave background, are thoroughly discussed. Various aspects of the dark matter problem, such as gravitational lensing estimates of galaxy masses, cluster evolution and hot cluster electron distortions of the thermal microwave background spectrum, are also discussed, as are particle physics candidates of dark matter and methods to detect them. Cosmic rays of matter and antimatter are included as a topic, and so is the problem of the enigmatic dark energy of the vacuum.

This book was released on 2003-01-16 with total page 921 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation The International Conference on Calorimetry in Particle Physics has become the major forum for state-of-the-art developments of calorimetry techniques. The tenth conference was attended by about 150 physicists from 20 countries and covered all aspects of calorimetric particle detection and measurements, with emphasis on high energy physics experiments as well as experiments in nuclear physics and astrophysics.The proceedings contain three parts: introductory papers, contributed papers and a summary. The introductory papers start with a historical review of the development of calorimetry technology, and continue with overviews of the current status of calorimetry in high energy physics and astrophysics, which are followed by discussions on calorimetry in future accelerator facilities, such as linear colliders and the Super B Factory.

Book excerpt: The International Conference on Calorimetry in Particle Physics is the major forum for the state-of-the-art developments of calorimetry technologies. The Tenth Conference was attended by more than 150 physicists from 16 countries and covered all aspects of calorimetric particle detection and measurements, with emphasis on high energy physics and astrophysics experiments.The proceedings contain three parts: introductory papers, contributed papers and perspective papers. The introduction starts with a historical review of calorimetry developments, and continues with overviews of the current status of calorimetry in high energy physics and astrophysics, which are followed by discussions on calorimetry in future accelerator facilities, such as linear colliders and the Super B factories. A “hot” technology regarding the “energy flow concept” is also discussed. The contributed papers are organized in 11 sessions. The perspective papers summarize the physics and limitation of calorimeter applications in high energy physics, astrophysics and medical industries.
