Beam Central Vacuum Systems, make beam vacuums. There is nothing particularly special about Beam vacuums. They are central systems which can be installed in any home. Typical central vacuums consist of a motor, waste filter, and several tubes running throughout the walls of the home where you attach the hose. Beam is a brand.
Hopefully this is what you mean.
It is possible to purchase a Beam central vacuum from the following places: Amazon, eBay, ShopBot, Nextag, McHardy Vac, Superior Vacuums, Think Vacuums, Beam and at Beam Vac.
This beam of electrons is emited by the cathode under voltage difference.
Theoretically, a vacuum is the absence of matter. The word "vacuum" comes from the Latin adjective "vaccus", which means "vacant". If a beam were to be pointed towards a vacuum, it would no longer exist due to the definition of what a vacuum is. Nothing exists once it enters the "vacuum".
The Beam Central Vacuum system would occasionally require replacement of parts for continued use as these parts do wear out. Some parts and accessories would be a vacuum hoses, as well as replacement attachments for the system.
Both beams travel at the same speed.

This point, the place where the electron beam strikes the anode, is generally called the target.
The base cost of a Beam vacuum system is $1,000. The cost then goes to the complications of the existing home structure, the number of outlets, the length, etc. If you are building a new home, this is the best and cheapest time to have one installed.
Depends on the amount of scattering. In fog, or in slightly cloudy water, it's easy to see a beam of light. In a vacuum, no scattering effects are seen.

It is not very clear what the question means. Light is an electromagnetic field and it can propagate in a vacuum. Propagation of a beam of light is unaffected by any other electromagnetic fields in its path.
