OK, I hope I got the idea of what you wanting.

The generators I used for the beam in effect are:

The Hanger Building.
Generator - Civilian 01 #1 (#157)
Generator - Civliian 01 #2 (#158)

The Tents
Generator - Civilian 01 #5 (#222)
Generator - Civilian 01 #6 (#223)


I hope this is what you want.

Hope this get fixed soon, with since I based this of the major floods 2 years ago the went through Queensland, Australia. And if you been keeping up with the news, I might need to beam down the generators again for Floods at Home Part 3.
