PSD for 1600 element microstrip detector D20 at ILL Grenoble
(Fast medium-high resolution machine) Pierre Convert et al.
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
