Their RF regulation is performed by a single cavity controller, implemented by an FPGA firmware and operating at 125 MHz. With a variant of the Struck SIS8300-KU controller board that is equipped with 250 MSps ADCs we were able to increase the frequency of the complete digital processing chain to 250 MHz. This includes the ADCs, field detection, feedback controller and DAC. Doubling the frequency reduced the overall controller latency by almost a factor of two. In the poster we show which firmware components had to be optimized or rewritten to achieve the 250 MHz clock rate. 000479818 536__ $$0G:(DE-HGF)POF4-621$$a621 - Accelerator Research and Development (POF4-621)$$cPOF4-621$$fPOF IV$$x0 000479818 693__ $$0EXP:(DE-H253)REGAE-20150101$$5EXP:(DE-H253)REGAE-20150101$$eRelativistic Electron Gun for Atomic Exploration$$x0 000479818 7001_ $$0P:(DE-H253)PIP1006406$$aHoffmann, Matthias$$b1 000479818 7001_ $$0P:(DE-H253)PIP1033284$$aGümüs, Cagil$$b2 000479818 7001_ $$0P:(DE-H253)PIP1007075$$aButkowski, Lukasz$$b3 000479818 8564_ $$uhttps://indico.psi.ch/event/12911/contributions/38408/ 000479818 909CO $$ooai:bib-pubdb1.desy.de:479818$$pVDB 000479818 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1090146$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000479818 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1006406$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000479818 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1033284$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000479818 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1007075$$aDeutsches Elektronen-Synchrotron$$b3$$kDESY 000479818 9131_ $$0G:(DE-HGF)POF4-621$$1G:(DE-HGF)POF4-620$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMatter and Technologies$$vAccelerator Research and Development$$x0 000479818 9141_ $$y2022 000479818 9201_ $$0I:(DE-H253)MSK-20120731$$kMSK$$lStrahlkontrollen$$x0 000479818 980__ $$aabstract 000479818 980__ $$aVDB 000479818 980__ $$aI:(DE-H253)MSK-20120731 000479818 980__ $$aUNRESTRICTED
