1. T. Le Flour LAPP OPERA Collaboration Meeting Gran-Sasso 1 TRACKING THE BRICK HANDLING From extraction to development

2. T. Le Flour LAPP OPERA Collaboration Meeting Gran-Sasso 2 Requirements Knowing the brick localization at any timeKnowing the brick localization at any time Knowing the entry/exit(?) of the brick in each work stationKnowing the entry/exit(?) of the brick in each work station Giving a way of accessing this set of information from anywhere :Giving a way of accessing this set of information from anywhere :  For each brick  For any work station Brick movement has to be tracked in “real time”Brick movement has to be tracked in “real time”  Matrix code reading will trigger a dedicated software component Software or network failure does not stop the process  Offline update will synchronize the brick movementSoftware or network failure does not stop the process  Offline update will synchronize the brick movement Procedures have to be clearly definedProcedures have to be clearly defined For the tracking, basic information as timestamp is neededFor the tracking, basic information as timestamp is needed  All sub-systems could enrich the basic information by linking is own set of information  Dedicated Graphical Displays could be proposed : Basic views for tracking only : Bricks or Work station viewsBasic views for tracking only : Bricks or Work station views More detailed views including the full informationMore detailed views including the full information Some logistic in some area (Shielded Area) will have to be foreseenSome logistic in some area (Shielded Area) will have to be foreseen

Le Flour LAPP OPERA Collaboration Meeting Gran-Sasso 3 From Extraction to Development/Re-Insertion Work Stations Brick Actions BMS/Supervisor/BMM current responsibility :BMS/Supervisor/BMM current responsibility :  Maintaining the detector content  Perform the brick extraction from the wall to the basket All steps during the extraction are time stamped : Extraction from wall, Insertion in the basketAll steps during the extraction are time stamped : Extraction from wall, Insertion in the basket All the bricks in the basket containing “candidates” are in well-known stateAll the bricks in the basket containing “candidates” are in well-known state  BMM knows exactly what are the bricks expected outside  A way to avoid the human error  only bricks in this list should be manipulated outside the basket.

4. T. Le Flour LAPP OPERA Collaboration Meeting Gran-Sasso 4 XRay Marking Work Stations Actions Bricks in the basket used for extraction have to be markedBricks in the basket used for extraction have to be marked Ideally, before each marking, reading the matrix code insure that only right brick will be markedIdeally, before each marking, reading the matrix code insure that only right brick will be marked Each matrix code reading set the brick in a new state with a timestampEach matrix code reading set the brick in a new state with a timestamp  Ie. : Brick received in XRay marking area at 00:00:00 00:00 This action should also fill in a electronic logbook associated to the XRay areaThis action should also fill in a electronic logbook associated to the XRay area In order to keep track of the brick path, a standard procedure has to be defined :In order to keep track of the brick path, a standard procedure has to be defined :  Manuals and automatic operations and the order have to be always the same.  REMARK : Do we need to know when the brick leaves this area ?

Le Flour LAPP OPERA Collaboration Meeting Gran-Sasso 6 Shielded Area Actions(2) A dedicated organization is needed :A dedicated organization is needed :  To locate precisely the brick location  To identify quickly the state of all the bricks  To avoid human errors,… Again, matrix code reader is the triggerAgain, matrix code reader is the trigger Some logistic is neededSome logistic is needed  Build around a shelves organization  Each place on shelves is uniquely identified  Each brick is associated to one and only one shelf place  Dedicated displays representing shelves, brick associated to shelve and brick state.

When a brick get out :When a brick get out :  Locating on a display the concerned brick location (matrix code typed by hand)  2 options : 1. Waiting the next trigger from the next work station 2.If knowing the release date is important from the current work station, operator will have to be done before the brick leaves the current area.
