It is therefore desirable to have an ECEI system on the ITER tokamak. However, the large size of optical components in presently used ECEI systems have, up to now, precluded the implementation of an ECEI system on ITER. This paper describes a new optical ECEI concept that employs a single spherical mirror as the only optical component and exploits the astigmatism of such a mirror to produce an image with one-dimensional spatial resolution on the detector. Since this alternative approach would only require a thin slit as the viewing port to the plasma, it would make the implementation of an ECEI system on ITER feasible. The results obtained from proof-of-principle experiments with a 125 GHz microwave system are presented.<\/jats:p>","DOI":"10.1063\/1.4884902","type":"journal-article","created":{"date-parts":[[2014,7,1]],"date-time":"2014-07-01T19:13:27Z","timestamp":1404242007000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Alternative optical concept for electron cyclotron emission imaging"],"prefix":"10.1063","volume":"85","author":[{"given":"J.
