All the mechanical stands supporting the optical components have been designed and surveyed in order to achieve a preliminary safe alignment of the entire setup (laser off). Initial setup of laser and optical system will be done while the laser hut window is closed (such that no laser beam will come out the laser hut). Initial alignment will be done with a standard class 3 HeNe laser (class 3A after attenuation, 650 nm) or a laser pointer (class 3A). The final alignment will be done with the diode laser. The beam can be tracked by the use of either an IR viewing card or an IR viewer. The photosensitive card can be displaced along the beam, and the IR viewer allows the tracking by the light slightly diffused on the optical components. During this final alignment, the laser hut window will be opened and the laser beam will be directed to the target, while the laser beam pipes and the laser enclosure on top of the target will be taken off. Therefore the whole hall will be classified as laser area. We will use the CANS system to have controlled access. Before the laser alignment starts, a sweep will be performed to clear the Hall. Then the CANS system will be programmed to only allow authorized laser trained persons to have access to the hall. The door to the BSY tunnel will be magnetically locked with a toggle push-button switch. The ``laser danger'' warning sign will be posted at all the entrances. The doors will be checked by pulling the door handle. In addition, a red flashing light will be put at the BSY side of the door. Most of the final laser alignment will be performed during night time to minimize interference with other work going on in the hall. When the alignment stops, all signs will be take off and the CANS system will be disabled and the door to BSY will be unlocked.
