5. Stainless steel attachment links
- Clockwise : collet, stainless steel tailpiece, Stainless steel band led twice through capstone and tightening the bond with the pliers.
The stainless steel attachment links (4) are stringed with an attachment grip (upper left corner in) around the aluminium beam (2) and concrete sidewalk profiles (1). The beam presses the two clamps (3) against the sidewalk profiles. The clamps stick out through the bottom of the ski box. The clamp locks/bolts on the clamps at the inside of the ski box ensure the tight mounting of the box onto the beam. The stainless steel toggle (bottom left) has joggles and ridges (upper right) with which the attachment link is kept under tension. With a hammer, the ridges are ‘bent’ around the attachment link. The attachment grip has a build-in cutting device with which the attachment link can be cut to length. 8 attachment links are mounted for each ski box.
- Fixing brackets and tubular section with stainless steel band.
Put the detector back into the box when the attachment links have been assembled. Note that the cable trays need to reach the ski box as far as possible and that the cables should exceed the minimum required length to the connectors of the PMTs.
The additional cable length is kept alongside the scintillator inside the ski box. Herewith, a simple strain relief for the cables and PMT is obtained. The cables are provided with two additional cable ties mounted close to the cable transit (they should not be cut short!). In this way an additional strain relief is created.
- The attachment links are fixed.
- The ski box is almost ready to be closed.
Each detection station possesses two sets of keys. One set is guarded by the school (blue label); the spare keys are collected and stored by the cluster coordinator (red label).
Finally, it is extremely important to properly close the lid of the ski box - the lid should match at all edges, while the key can be turned without applying any force. Ofcourse, no plastic foam should be left inside the ski box on top of either the scintillator or the light guide.
- Ready to measure cosmic particles!
DISCLAIMER: The anchoring method described in this document has been developed on the basis of information provided by the manufacturer of the ski boxes and has been verified by mechanical engineers. The method has proven itself over the past years. Modification in any way of this method will be your own responsibility and is strongly discouraged!
