1. : adding and removing zones from Federal University of Rio de Janeiro CHEP’09 International Conference on Computing in High Energy and Nuclear Physics 21-27 March 2009 Prague, Czech Republic Introduction The running of the Large Hadron Collider exposes the ATLAS detector to radiation. Therefore, CERN shall follow specific regulation from French and Swiss authorities for equipment removal, transport, repair, and disposal. During the operation, maintenance, and dismantling periods of the ATLAS Experiment, the traceability of all detector equipment must be guaranteed for logistic and safety matters. The system described has been developed to track location, monitor radiation, and store property data of thousands of equipment within the detector facilities.

The ID can be entered through a barcode reader that reads the label sticked to the equipment. When created, the part is associated to an ATLAS system, a type of equipment related to that system, and a responsible. If the equipment doesn’t have a label, a new meaningful ID can be generated Setting the radiation background Automatic or manual input The value of the local radiation background gets stored using the radiation monitor. The threshold used for the equipment dose is one and a half the average of the background value during the measuring time. Only radioprotection experts are allowed to access this functionality. Actors The ATLAS equipment management inside and outside the cavern is handled by people with different roles in the experiment, which are managed by specifics privileges on the system and they are listed below: Radioprotection Expert - person trained to handle radioactive parts and nuclear waste. Material Responsible - has the responsibility to ensure the correct handling of his material Workshop/Institute Manager - in charge of the equipment management in its workshop or institute ATLAS systems user – responsible for equipment in the conventional non radioactive zone of a specific sub- detector, or general infrastructure and services. Glance Retrieval Tool The Glance Traceability system is based on a Glance API developed in C++ that makes possible to retrieve data from heterogeneous data repositories. The API provides the data queried in a XML description, that is parsed and interpreted by the system. Architeture Measuring dose, modifying data and printing labels Multiple equipment management History for location traceability and radiation measurements are displayed on the interface. Radiation control of equipment is performed using a radiation monitor connected to the system. If the dose measure exceeds the background, an alert message is displayed. If a person, the responsible must be registered at CERN Managing locationsthe list Software fully operational Adapted to the LHCb experiment Next steps - Integrate with the CERN ISRAM waste database - Manage storage of equipment/tooling in specific area workshop/buffer zone. Storage of radioctive equipment should also be foreseen. Conclusion Schematic views of the detector 3D view of a Larg Barrel Online search for available boards in creates ATLASlocation3D View of HS/HO levels and racks Allows radioprotection experts and systems users to associate equipment parts to functional positions inside the ATLAS cavern Offers a schematic view of the ATLAS detector, identifying the nuclear zone, and splitting the sub-detectors. A three dimension view of the detector is also provided for the location choice. 3D view Small wheel Interface / Peripherals The label printer and the radiation monitor communication is achieved through java applets. Another value-added-service is ATLASlocation3D, a GUI in java / java3D, which synthesizes a 3D view of ATLAS starting from geometry data stored in the database.
