Raimondi-Seryi Final Focus for e+e- Factories? Frank Zimmermann, Factories’03 Motivation Design History The Challenge

Some problems encountered in B factory upgrade designs: Stronger quadrupoles closer to the IP Limited dynamic aperture

In 2000 P. Raimondi and A. Seryi at SLAC proposed a new ‘Compact Final Focus System’ for Linear Colliders [Phys.Rev.Lett.86:3779-3782,2001] Since then most linear collider proposals (NLC, CLIC, and TESLA(?)) have adopted the Raimondi-Seryi scheme, which offers numerous advantages.

Nick Walker’s illustration at Nanobeam’02

Advantages compared with conventional system: Increased momentum bandwidth Much shorter length Fewer and weaker quadrupoles Larger free distance between last quad and IP Improved dynamic aperture Possible disadvantage: Slope of dispersion at IP could drive synchro-betatron resonances., but probably much less than a crossing angle

In April 2001, on only one day P. Raimondi designed a compact low-beta optics for a 30-TeV Muon collider with a large geometric beam emittance. Several optics experts had worked for a couple of months on a conventional system and failed miserably. The compact optics showed an excellent performance over multiple turns and a huge momentum acceptance !

“Similar designs could also be considered for high luminosity factories based on storage rings, where the dynamic aperture could be improved even with very small vertical beta functions at the IP.” P. Raimondi & A. Seryi, May 2000.

Design procedure for this type of optics was presented by Andrei Seryi and his colleagues at Nanobeam02 and PAC2003. Experimental tests are “not necessary” (Nanobeam’02 summary Tor Raubenheimer) My questions: Why still work with ancient schemes? Can this workshop come up with the first modern factory-IR optics design?
