  3. MSGC : a fragile structure MSGC DISCHARGE PROBLEMS: FULL BREAKDOWN MICRODISCHARGES

  4. MSGC at ILL ILL Grenoble Microstrip Detectors Diffraction Group � The wires are replaced by a printed circuit on a glass substrate � A high electric field is produced around the thin anodes. � The glass substrate is electrically conducting to remove charge build-up Oed et al. � PSD for 1600 element microstrip detector D20 at ILL Grenoble (Fast medium-high resolution machine) Pierre Convert et al. A. Hewat, China Nov/Dec 2000
