11 ARD Test FacilitiesCarsten Hast - ARD Test Facilities Department11 ESTB Detector Test Area Beam spot:  < 1mm

12 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 Department12

13 ARD Test FacilitiesCarsten Hast - ARD Test Facilities Department13 ESTB Status New BSY kicker magnets, power supply and vacuum chambers –All items are in the design and purchasing stage (based on existing hardware) –Will be installed during the down March/April 2011 New small beam dump for ESA –Design is clear –Radiation protection calculations are ongoing –Will be installed early 2011 New Personnel Protection System (PPS) –Design has started and implementation plan is under development –Scheduled to be done by June 2011 There will be a User Workshop at SLAC Thursday, March in conjunction with 2011 Linear Collider Workshop of the Americas (ALCPG11), University of Oregon in Eugene, March 19-23, 2011 First beam summer 2011

21 ARD Test FacilitiesCarsten Hast - ARD Test Facilities Department21 Coherent Optical Transition Radiation Gerard Agostino Diktys

22 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

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 FacilitiesCarsten Hast - ARD Test Facilities Department23
