20. X-Band Test Area Carsten Hast - ARD Test Facilities Department

21. Coherent Optical Transition Radiation Agostino Gerard Diktys ARD Test Facilities Carsten Hast - ARD Test Facilities Department 21

22. 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 ARD Test Facilities Carsten Hast - ARD Test Facilities Department 22

23. 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 Facilities Carsten Hast - ARD Test Facilities Department 23
