Introduction to Experimental Particle Physics
This book brings together the most important topics in experimental particle physics in the late twentieth century to give a brief but balanced overview of the subject. The author begins by reviewing particle physics and discussing electromagnetic and nuclear interactions. He then goes on to discuss three nearly universal aspects of particle physics experiments: beams, targets, and fast electronics. The second part of the book treats in detail the properties of various types of particle detector, such as scintillation counters, Cerenkov counters, proportional chambers, drift chambers, sampling calorimeters, and specialized detectors. Wherever possible the author attempts to enumerate the advantages and disadvantages of performance. Finally, he discusses aspects of specific experiments, such as properties of triggers, types of measurement, spectrometers, and the integration of detectors into coherent systems. First published in 1986, this title has been reissued as an Open Access publication
Ultrasonic transducer calibration
When a material is placed under stress, small
changes within the specimen release ultrasonic energy
in the form of stress waves. The change may, for
example, be a dislocation movement or the advancement
of a crack tip. These ultrasonic pulses are termed
Acoustic Emission and may be detected at the material
surface by ultrasonic transducers. The detected pulse
shape is related to the generating source, to the material
geometry through which the pulse propagates and to the
response of the ultrasonic transducer used to detect the
waves. Work has been carried out to measure both the
effect of wave propagation and to calibrate the response
of ultrasonic transducers.
Three types of ultrasonic wave may exist in a material
with a non-zero shear modulus; these are longitudinal waves,
shear waves and surface or Rayleigh waves. In a large
number of specimen geometries, the surface wave has the
largest amplitude. The response of a transducer to this
wave is therefore very important. Most transducers respond
to the out of plane motion of a material surface carrying
ultrasonic waves. Therefore, to successfully calibrate
a transducer, some absolute measurement of the out of plane
motion due to surface waves must be made. An interferometer
has been designed and constructed for this purpose.
The calibration of ultrasonic transducers has enabled
some development work to be carried oLt on high-fidelity
piezoelectric transducers and on piezomagnetic transducers.
It is not always possible to measure an ultrasonic pulse
directly with a calibrated interferometric detector and
therefore to enable a wider range of propagation problems
to be investigated, various methods of ultrasonic pulse
generation have been studied. These artificial sources
of acoustic emission have included brittle fracture, laser
impact and stimulation by piezoelectric transducers. This
work has enabled theoretical calculations on pulse
propagation to be verified
Particle Physics Reference Library
This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the “Particle Physics Reference Library” provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A,B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
LUX-ZEPLIN (LZ) Technical Design Report
In this Technical Design Report (TDR) we describe the LZ detector to be built at the Sanford Underground Research Facility (SURF). The LZ dark matter experiment is designed to achieve sensitivity to a WIMP-nucleon spin-independent cross section of three times ten to the negative forty-eighth square centimeters
