Vertical space will be available if the pulser boxes are definitively placed on the midlevel racks this decision awaits understanding of light attenuation in the pulser fibers. There was a strong sense of the meeting that the horizontal configuration was preferable, and that we should make them as wide as can be achieved with the final pulser positioning, rack mini-monitoring, etc. Far Detector frontend electronics mounting John Oliver John presented a model of mounting which has a front end board with 3 small connectors and holes for 4 light-tight screws. There is another board on the inside which must also have a few screw holes. The assembly model is to assume that a light-tightened unit is presented to him to attach to, so that no leaks will be generated.
Access is needed to both ends of the boards.
Given the space constraints mentioned above, it was the consensus of the group that side-mounting should be pursued. We are assuming that there is no cooling issue in the far detector the tube bases are very low power and there is little electronics heat. This should be watched however. At this time we took a decision on horizontal MUX boxes, deciding to use this option. Although this unit was made of aluminum, steel ones could be fabricated.
