BernScanServer Tool to debug the complex
Microscope Robot Controlled by TCP in a simple
way, executes methods of VertigoScan which are
executed by normal ScanServer Task to do
measure relative plate positioning precision

Scanning progress Vertex search CERN TB Nov 2004
CS dublet 105 x 85mm scanned 2603 tracks
found 860 are within beam angular distribution
(60mrad) Brick 20x20mm 32 emulsions are scanned
and aligned with old style FMs.

Z-distance Good alignment on beam tracks, But no
reliable coinsidence for large angle
particles. Work is in progress.
