EBOLII:
Listen, you can't use a noise map for a tractor beam using a volume light - it would seem logical yes but a noise map is procedural and that means it's 3d not 2d so when you apply a noise map to the volume light you'll get a visible cone with noise in it instead of beams. But if you render out the map on a plane (animated would be best) you'll then be able to use this map on the volume light to cast that particular map and get the beams you want. Make sure shadow casting is on!
