Personnel Safety/ Working in the Hall

When the installation of the full target setup is finished, working in the hall shall be safe from laser light hazards or target explosion hazards, because laser light as well as the target cell will be safely enclosed. Therefore when considering the overall aspects of the safety of personnel working in the Hall two distinct periods are to be considered.

1. One period is during the laser beam alignment because the laser beam pipes from the laser hut to the target need to be removed. During this time period we will ensure that no other person except those people who are laser trained and qualified for laser beam alignment are in the hall. This will be arranged by using a controlled access to the Hall provided by the CANS system. This alignment will be performed only during the night time and weekend. Clear warning signs will be posted at the entrance of the Hall when the alignment is under progress.

2. One period is during the setup of the high pressure target cell in its final position. In this case the ``target platform'' which is a natural perimeter around the target area will be marked and signs posted requiring the wearing of ear protection and faceshield. Beyond that defined perimeter all personnel working in the hall will not be affected in case of explosion of the cell if they are not wearing a faceshield. Nevertheless, it is strongly recommended to have ear protection when working anywhere in the Hall.
