Description
Heavy utilisation of the access system during LHC hardware commissioning has uncovered shortcomings in the performance of the system. While generally available to operation as required, response of the system has sometimes been below expectations of its users and operators. Reasons for these problems are both technical and procedural. Issues have been found in both hardware and software as well as in the system's response to external factors, such as network problems. Real-world usage of the access system has also not always reflected its original design.
Possibilities for improvement exist: It should be possible to automate some of the administrative checks by the operators in the restricted mode. The access cycle may be streamlined, and new lighter-weight access modes for specific situations may be investigated. User interface improvements are possible to facilitate management of multiple access points at busy times.
The exact actions to be taken will need to be evaluated between the access and operational teams. The most important issues affecting the performance of the system should be addressed first to ensure the best possible service to the users during the next shutdown.
