Cosmic Microwave Background Radiation
Reviews of Modern Physics, 1999Most astronomers and physicists now believe that we live in an expanding universe that evolved from an early state of extremely high density and temperature. Measurements of the spectrum and anisotropy of the cosmic microwave background radiation (CMBR) provide strong evidence supporting this picture. Today, the spectrum of the CMBR matches that of a 2.

1976 International Conference on Submillimeter Waves and Their Applications, 1976
The existence of essentially isotropic homogeneous cosmic background radiation with the spectrum of a 3 K blackbody places important limits on cosmological speculations. This radiation has been the subject of intensive experimental investigation for more than a decade.

A Background to Background Radiation
The Physics Teacher, 2003The study of radiation at the introductory college level usually includes experiments to determine the half-life of a radioactive isotope and also a study of the absorption of nuclear radiation by metal foils. These experiments are straightforward to do using a Geiger-Müller tube and scaler, and allow for the determination of well-known constants.

The cosmic microwave background radiation
Reviews of Modern Physics, 1979Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe. This paper is about the discovery

DarkLight radiation backgrounds
AIP Conference Proceedings, 2013We report measurements of photon and neutron radiation levels observed while transmitting a 0.43 MW electron beam through millimeter-sized apertures and during beam-on, but accelerating gradient RF-on, operation. These measurements were conducted at the Free-Electron Laser (FEL) facility of the Jefferson National Accelerator Laboratory (JLab) using a ...
