Circular accelerators will always produce gyromagnetic radiation as the particles are deflected in the magnetic field.  However, the quantity and properties of the radiation are highly dependent on the nature of the acceleration taking place.  For example, due to the difference in mass, the factor of <math>\gamma^4</math> in the formula for the emitted power means that electrons radiate energy at approximately 10<sup>13</sup> times the rate of protons.<ref>{{cite book |last1=Conte |first1=Mario |last2=MacKay |first2=William |title=An introduction to the physics of particle accelerators |date=2008 |publisher=World Scientific |location=Hackensack, N.J. |isbn=978-981-277-960-1 |page=166 |edition=2nd}}</ref>

Energy loss from synchrotron radiation in circular accelerators was originally considered a nuisance, as additional energy must be supplied to the beam in order to offset the losses.  However, beginning in the 1980s, circular electron accelerators known as [[synchrotron light source|light sources]] have been constructed to deliberately produce intense beams of synchrotron radiation for research.<ref>{{cite web |title=History: Of X-rays and synchrotrons |url=https://lightsources.org/history/ |website=lightsources.org |date=21 September 2017 |access-date=13 December 2021}}</ref>
