Monochromatization Option for NLC Collisions(LCC-0134)
- SLAC
In this note, we consider an option for NLC operation where the Interaction Point beam parameters are adjusted in order to increase the energy resolution. This is achieved by squeezing the horizontal betatron function at the IP and simultaneously introducing a horizontal dispersion (with a different sign for electron and positron beams). While the total horizontal beam size remains constant, the beam is now spread in energy in the horizontal plane so that lower energy particles collide preferentially with higher energy particles. The resulting luminosity spectrum becomes sharper and any possible ''energy bia'' is reduced by more than a factor of two. This option is viable as long as the energy jitter is smaller than the energy spread, as expected.
