Designing the TESLA interaction region with L* = 5 M |
O. Napoly, J. Payet |
We study the main implications of increasing the last drift length l* from 3 to 5 meters, in the TESLA interaction region: namely, the design of a new final focus system with a better chromatic correction, the extraction of the beam after the collision through the opposite doublet, and the new collimation requirements. |
