Undulator Radiation Observed March 10, 2010
Today at 3pm we observed clear undulator radiation from the first modulator in the Echo-7 beam line at NLCTA. The Pi-mode together with the sigma-mode of the undulator radiation gave us four-lobes, please see attached picture. The number of photons is estimated to be about 10 million which should be sufficient for the fast photodiode. We'll test laser and electron beam timing later this week. So stay tuned for more good news.
Congratulations to Dao, Janice, Doug, Stephen, Pierre-Louis, Mark and Michael, who were present in the control room, and all others who are working hard to make Echo-7 happen.
