Abstract

We present the inaugural results in the development of a dedicated medical imaging MSGC. Utilizing a standard 200μm pitch pattern (80μm cathodes, 10μm anodes) on 1 mm thick D263 glass and a 1 cm drift region, we obtained energy resolutions of 27.3% FWHM [full width at half maximum] and 17.7% FWHM in P-10 and Argon/Ethane/DME [78.5/20/1.5], respectively using an ⁵⁵Fe source. Gas gains of 399 in P-10 and 1,297 in Argon/Ethane/DME were achieved. Large energy depositions from ¹⁰⁹Cd, ⁵⁷Co, ¹²⁹I photons did not induce breakdown in Argon/Ethane/DME at moderate cathode strip voltage (Vc = -549 volts*).
