Publication of new CRES measurements
March 6, 2017
We announce the publication of a review of recent results from the Project 8 expriment, including a new measurement of 83mKr conversion electrons.. We measured the 30 and 32 keV conversion electrons with resolutions of 3.3 and 3.6 eV (FWHM), respectively. The paper was published in Journal of Physics G (J.Phys. G44 (2017) no.5, 054004), and can be found on the arXiv (1703.02037).
Publication of the CRES Discovery
April 20, 2015
The paper announcing the first detection of single-electron cyclotron radiation and the first application of the CRES technique has now been published in Physical Review Letters: Phys. Rev. Lett. 114, 1162501 (2015). The article was highlighted as an Editors' Suggestion. You can also read the Viewpoint commentary on the article written by Patrick Huber.
First Observation of Single Electron Cyclotron Radiation
August 25, 2014
The Project 8 collaboration is proud to announce the first observation of relativistic cyclotron radiation from single electrons! We detect individual electrons from a gasseous 83mKr source. Since the frequency of the relativistic cyclotron radiation is inversely proportional to the kinetic energy of the electrons, we use this technique to make a spectroscopic measurement of the 83mKr internal conversion electron lines. This new spectroscopic technique is called Cyclotron Radiation Emission Spectroscopy (CRES). Please see the preprint of our paper announcing these results for more details.
