TI - Beam Jitter Spectra Measurements of the APEX Photoinjector
J2 - Proc. of IBIC2014
AB - High repetition rate photoinjectors such as the APEX at LBNL are one of the enabling technologies for next generation MHz XFELs. Due to the higher repetition rate, a wider bandwidth is available for feedback systems to achieve ultra-stable beam performance. In a first step to improve APEX beam stability, the noise power spectra of the APEX laser beam and electron beam are characterized in terms of intensity and timing. Possible feedback systems are also discussed.
