Enlisted Help! Mauro joined the ESTB team and will lead the effort to make ESA “usable” again –Need to reinstall BPMs which are on loan to Berkley –Complete the beam line –Install a dump –Improve the experimental infrastructure –Clean Up!!!!!!!!!!!

ARD Test FacilitiesCarsten Hast - ARD Test Facilities Department22 Coherent Optical Transition Radiation Goal of the experiment: Reconstruct transverse distribution of micro-bunching in amplitude and phase Far Field only Far Field and Near Field simultaneously Phase can be found with a phase retrieval iterative algorithm We have invited Diktys to give a seminar about that next year

Preliminary Results Decent signal from microbunching instability but few photons survive after bandpass filter Unexpected Interference pattern in the far field zone Pattern appears at two locations along NLCTA Etalon effect in the exit vacuum window? Near future plans: COTR imaging and ECHO experiments are compatible More data will be gathered during ECHO runs with motorized camera lenses ARD Test FacilitiesCarsten Hast - ARD Test Facilities Department23
