Synchrotron radiation loss in a kissing ep geometry

The desirability of the kissing geometry to bring about collisions between electrons in the Main Ring and protons in the Doubler is examined. Because of the large energy asymmetry between the electrons (12 GeV) and the protons (1000 Gev) the kissing geometry seems at first attractive. The electron beam can be brought down and up from its original height to the proton beam height with little difficulty. The proton beam would require no change in its original direction. The power consumption due to synchrotron radiation losses are considered, and ways to reduce these losses through magnet design are mentioned
