1. TecnoCut PlateChanger Set Up /1 2009.01.09 videoconferenceG.Sirri - INFN Bologna1 HARDWARE (complete):  both glued / not glued emulsion setup  cabling of the interface [PlateChanger - LNGS level adapter board – NI7344]  cabling and pneumatic connection of the air/vacuum device for the glass window  cabling and pneumatic connection of the oil dispenser  oil dispenser mechanical support (new design by LNGS) additional tools:  frame press to help vacuum on the glass window (new design by LNGS)  compressed air nozzle to help emulsion detachment from the glass window (electrovalve, cabling, pneumatic connection and mechanical support)  compressed air to help emulsion detachment from the cleaning tool surface (electrovalve, cabling, pneumatic connection)  proximity switch to inhibit microscope movements when platechanger arm is over the glass window (switch, cabling, mechanical support) Red: what’s new after last comunication (2008.10.29)

2. TecnoCut PlateChanger Set Up /2 2008.10.28 LNGSG.Sirri - INFN Bologna2 FIRMWARE (complete - version 4):  platechanger state can be read outside for synchronization with the software  emulsion counter is removed  an additional input signal is provided to manage the (un)load of the last emulsion plate  provide compressed air to help the emulsion detachment from the cleaning tool surface  provide vacuum when the arm put the emulsion on the cleaning tool surface SOFTWARE (minimal software available):  Basic Digital IO interface complete (through new module FlexStage5)  Scanning process integrated with oil distribution (customized VertigoScan7)  Fiducial Mark Finding integrated with oil distribution (new FlexMapX)  macros to manage the Load/Unload/OilDispense jobs (new module TCPlateChanger) Synchronization with the platechanger to improve reliability at startup, after failures, … (manage problems like: “load” command received when “unload” is expected, restart after software or platechanger crashes, … )

3. TecnoCut PlateChanger Set Up /3 2008.10.28 LNGSG.Sirri - INFN Bologna3 TEST AND MEASURE:  Full brick load/unload skipping oil (mark finding, area scanning, …) : ok (glued/not glued)  Scanback and totalscan of some bricks (oil distribution included) : (after tuning of mark finding and platechanger alignment tools) not glued: too lateral mark finding failures (focus problems outside the vacuum channel due to oil) glued: ok … but frequent cleaning of separators, suckers, surfaces, …

4. Conclusions 2009.01.09 videoconferenceG.Sirri - INFN Bologna4 The hardware and firmware set up can be considered closed for what concerns the requested functionalities. Mark finding improvements useful for not glued emulsions (in progress): manage and/or trace the lateral mark “clone problem” focusing before lateral mark search Now, standard measures are necessary to verify the reliability and stability of the system.
