The first operation of GEM gas gain elements in negative ion gas mixtures is reported. Gains up to several thousand were obtained from single-stage GEMs in CS vapor at low pressure, and in mixtures of CS2 with Argon and Helium, some near I bar total pressure. (C) 2004 Elsevier B.V.

Comment: 17\'eme Congr\'es Fran\c{c}ais de M\'ecanique, troyes : France (2005)
Axion-like particles produced in the sun with masses in the keV range have been proposed to explain several long-standing anomalies in astrophysical X-ray observations. The gravitationally bound massive axions could be observed decaying to two X-ray photons in an instrumented underground detector volume. We propose to use a 1.5m(3) Negative-Ion TPC instrumented with GEM/Micromegas pad readout to perform a sensitive search for keV range axions. The sensitivity of the proposed experiment will be five orders of magnitude below existing limits after one year of running.
Comment: 5 pages, 2 Figures Talk given by M. Artuso at 8th Pisa Meeting on Advanced Detectors, May 2000
The CLEO-III Detector upgrade for charged particle identification is discussed. The RICH design uses solid LiF crystal radiators coupled with multi-wire chamber photon detectors, using TEA as the photosensor, and low-noise Viking readout electronics. Results from our beam test at Fermilab are presented.
