Schematic structure of the two-dimensional MSGC which was formed on a 17 µm thin polyimide substrate. On the polyimide layer, 7 µm-wide anodes and 63 µm-wide cathodes were formed with a 200 µm pitch (the width of the cathodes was changed to 100 µm in the imaging measurement as mentioned in §4). Between the ceramic base and the polyimide substrate are set back strips with a 200 µm pitch orthogonal to the anodes. All electrodes are made of gold with a thickness of 1 µm. To define the drift field, the drift plane was placed at 10 mm above the substrate. |
