Claim Text:
1. A method of controlling incoherent synchrotron radiation (ISR) and coherent synchrotron radiation (CSR) in a high brightness electron beam comprising: a. providing a super-periodic second order achromat line comprising a plurality of superperiods, wherein each superperiod in said plurality of superperiods includes a plurality of dipoles and quadrupoles and each superperiod is linearly achromatic and isochronous, the electron beam including a bend angle and a bend radius at each of said dipoles; b. providing a tune for each superperiod, wherein each of the tunes provides the frequency of the transverse oscillation for the corresponding superperiod; c. setting the tune for each superperiod to a rational fraction of an integer; d. setting small individual bend angles to reduce driving terms due to dispersion and dispersive angle; and e. setting the bend radius of the electron beam at each of said dipoles to a value that will suppress ISR and will limit the radial dependence of CSR.
