Calorimetry probe for runaway electron heat load measurement at COMPASS.

Runaway electrons, accelerated in a tokamak discharge to high energies (tens of MeV), can cause serious damage to plasma facing components. Therefore, it is important to develop effective mitigation strategies to reduce the risk of tokamak damage. To study the effects of various mitigation strategies, a dedicated diagnostic, the calorimetry probe, was developed at the COMPASS tokamak.

Respecifying social change: the obsolescence of practices and the transience of technology.

This article proposes that social change, a fundamental topic in sociological theory, can be productively revisited by attending to studies in ethnomethodology and conversation analysis (EM/CA). We argue that the corpus of EM/CA research, from the 1960s until the present day, provides details of the constitutive and identifying aspects of practices and activities that gradually transform into descriptions of practices and activities, and that this corpus can be revisited to learn about the ways people used to do things. Taking landline and mobile telephony as a case in point, we show that the subtle details of conversational practices are anchored in the technology used as part of the contemporary lifeworld, and that they stand for the particularities of routine social structures of their time period.

"For Example" Formulations and the Interactional Work of Exemplification.

Members in society make ubiquitous use of examples as a resource to engage in their everyday and specialized activities. This paper takes the resourcefulness of exemplification as a topic of inquiry by focusing on the formulative phrase "for example," investigating its interactional work within the analytic framework of ethnomethodology and conversation analysis. The data used consists of 11 h of video-recordings of English as a Foreign Language classroom lessons over a semester.

Harold Garfinkel and Edward Rose in the early years of ethnomethodology.

This article documents the beginning of the intellectual companionship between the founder of ethnomethodology, Harold Garfinkel, and Edward Rose, who is most often associated with his program of "ethno-inquiries." I present results from archival research focusing on the contacts and collaborations between Rose and Garfinkel in the years 1955-1965. First, I describe the review process for Rose and Felton's paper, submitted to the American Sociological Review in 1955, which Garfinkel reviewed and after Rose's rebuttal recommended for publication.

Radiometry for the vertical electron cyclotron emission from the runaway electrons at the COMPASS tokamak.

Due to an increased interest in runaway electron (RE) phenomena in tokamak research, the need for diagnostics of runaway electron population in plasma has emerged. A novel diagnostic of the nonthermal electron cyclotron emission from runaway electrons can be utilized for this purpose. It was designed and installed at the COMPASS tokamak based on the available heterodyne radiometer.
