Real-time transverse emittance diagnostics
With the increasing interest in high-brightness beams and the recent advances in photoemission guns capable of producing such high-charge, low-emittance beams, measuring transverse emittance has become a primary concern, especially in driver accelerators for free-electron lasers (FELs) where a degradation of this parameter could result in significant deterioration of the FEL gain. Hence, frequent and fast measurement are needed, particularly when detailed parametric studies are required. Commonly used methods include optical transition radiation (OTR) based methods and trace space sampling methods. The authors will discuss these methods and provide motivation for their method of on-line emittance measurement in the Jefferson Lab FEL.
