Particle Detectors, Reproducing Double Slit Experiment

[Kylonicus]

Hi, I would like to reproduce Young's Double Slits experiment, except I would like to use a particle detector to observe the information, so that when I deleted the information I could create the original pattern.

 

I've got money to blow, and I would really like to reproduce this experiment.

 

Anybody know the specific type of particle detector it would take? Also, does anybody know what the general cost of a particle detector is?

 

I went to Ortec, but so far I haven't found out their prices.

 

Anyway, any feedback would be helpful.

A CCD should work.

Thanks for your input, it is much appreciated.

I was wondering, do you know if that would cause the experiment to act like it was observed?

 

Also, how high of resolution of a charged couple device(CCD) would I need in order to act as if it were observed?

 

Also, I was wondering, would the CCD have to be the substrate where the light hits in order for the quantum effect to occur, or could I just set this up and measure it without it being where the light hits? Would I need to set this up where the CCD was being hit directly by the light(I am thinking I would) or could I just set this up to the side and it would cause the change to occur?

 

I think your suggestion is wonderful, I am just sketchy on what resolution of a CCD I might need.

 

Thanks again for any input you may give.

Your resolution will be dictated by how you set up the experiment. The light from the double-slit needs to hit the CCD directly, and the pixel size needs to be smaller than the distance between the maxima and minima, so you can tell the difference. You'd probably want to have several pixels fit into the distance between a max and a min. This distance depends on the slit separation, distance to the screen and wavelength of the light.

Thanks again, you are an inmeasurable help.

wouldn't construction paper with two slits and a light bulb do the job?
