As far as I'm concerned the efficacy, of the Double Slit experiment comes into question as in fact electromagnetic energy can either be reflected, scattered or absorbed such that one can't be sure that the patterns seen weren't due to the lack of controls to ensure otherwise.
The following questions are just a few that would have to be considered to ensure accuracy:
What element was the plate made of?
How was the plate machined, to what surface texture?
How thick was the plate?
How were the slits closed off?
Was the angle of the electron gun always perpendicular to the plate to within 1 electron or was it a sweeping motion on a pivot point?
Was the plate ferrous, or nonferrous?
What was the magnetic moment of the plate?
How did the plate material react to bombardment of electrons besides heating up?
Was the heating compensated for? By what means, mathematically or physically?
Electrons ricochet, so an angular strike on the thickness facet of the plate would cause a pattern not directly behind the slits. Elements with an odd number of valance electrons more easily receive and release electrons, as opposed to those with an even number of valance electrons. Of course there's more to consider, than this.
This should be common sense to you guys, as all one has to do is ask, "how the particles at CERN's LHC remain in the center of a circular accelerator?" Of course the answer is electromagnetic fields much like a television creates it's raster scan.
Here's an example of the kinds of things I'm talking about.
This happens to be about the STEHM (Scanning Transmission Electron Holography Microscope), the world’s most powerful microscope.

"The microscope itself is a 4.5-metre tall cylinder
encased in metal shielding to block magnetic fields. It has a footprint of six square metres and weighs seven tonnes.
The microscope is so huge that researchers will climb a stepladder to insert their specimens through a tiny airlock into the vacuum of the column. They’ll then leave the room,
wait for the air currents in the room to calm, and then
operate the microscope remotely from an adjoining room.
The microscope is so sensitive that its
image could be affected by little more than a passing cloud.
For this reason, it is housed in the basement of UVic’s science building in a special self-contained, extra-tall
room that is anchored to bedrock and encased in eight inches of insulation sandwiched between layers of galvanized steel.
The outer walls of the room are
shielded with aluminum to block electromagnetic waves, and the inner walls are
lined with acoustic and cooling panels to minimize vibration and control temperature variation to no more than 0.1 degrees per hour.
The room is also pressure-controlled."
The above talks of controls to ensure accuracy of information. Obviously, the smaller one goes the more precision is required.
There are many more questions that would have to be answered before one could be certain the findings of the double slit experiment are accurate. If you don't think so, just don't say so, provide proof to the contrary. How much do you actually know about the experiment?
