I.Kreslo / LHEP BERN1 Status of scanning in Bern HW status SW status pi/mu separation ( PSI 2004 ) vertex search (CERN 2004)

I.Kreslo / LHEP BERN2 Hardware status 2 Microscopes are still working MC1310 problem (image flicker – temp. solved) Robot: plate taking problem and solutions -> see below Server : – on since 4 monthshttp://lheppc46.unibe.ch

I.Kreslo / LHEP BERN3 Robot performance Plate taking problem is solved!! Change time 30s + FM scan time => ~90s X position, microns Y position, microns Limited by : - storage bank geometry - arm rigidity – negl. - encoder problems!!!

I.Kreslo / LHEP BERN7 Software status Contributions to SySal developement FlexMap3 is under development Tasks: automated FM scan - debugging new style FM with ID coding – in progress

I.Kreslo / LHEP BERN8 Software status Contributions to SySal developement 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

I.Kreslo / LHEP BERN9 Software status Contributions to SySal developement VertigoScan3: Added slot for PlateChanger Added method template for automated FM scan No backward compatibility -> New Version 4? (Preliminary – auto FM scan is invoked indirectly: not a transparent solution) To be discussed…..
