Interview with Allen Odian, Permanent Staff Physicist Emeritus at SLAC. Odian discusses his current work on the EXO 200 double beta decay search for xenon, and he recounts his Armenian heritage, his upbringing in Boston, and his early realization that he wanted to be a physicist. He describes his undergraduate work at MIT, and he explains his decision to remain there for graduate school to work at the synchrotron laboratory run by Louis Osborne. Odian discusses his thesis research on proton pairs under the direction of Al Wattenberg, and he describes his postdoctoral work in pulsed electronics at the University of Illinois. He explains his decision to pursue a Fulbright scholarship to work on the 1 GeV accelerator at Frascati, Italy, before returning to take a job at SLAC just as the lab was coming together. Odian conveys the frenetic pace of building and research during SLAC’s early years, and he describes Shelly Glashow’s direction to look for charmed mesons. He discusses his work on the streamer chamber, and he describes the interplay of theory and experiment for SPEAR. Odian describes his work for the SLC positron source and his advocacy for a streamer chamber at the SSC. He explains the significance of the Askaryen effect, his involvement in the development of the Fermi telescope and his research on the inverted polarized electron gun. Odian discusses the SLC’s value for millicharged particle research, he explains the origins of EXO 200 and his work on the heavy photon search at JLAB. At the end of the interview, Odian reflects on how his experimental work has provided guidance to theorists, he conveys the centrality of Panofsky’s vision and leadership at the center of SLAC’s success, and he explains his ongoing curiosity about the possible existence of Majorana neutrinos.
