    Conference Opportunities for Nuclear/High Energy Physics in March 2014

    I have just heard some good news that I will get funds to join a conference/meeting/workshop. This event must be held until the end of March. I am interested in any event on nuclear/high energy physics. Preferably I would like it to be on intrumentation/detectors but there is a flexibility...

    Investigating Possible Impurities on RBS Spectra of a Rhodium-Silicon System

    Unfortunately, all I've got is the attached experimental data;nothing else... It's a possible scenario, but I doubt if I can prove it with the simulation. One thaught, was that the vacuum wasn't well built, so I thought to add a layer of oxygen and nitrus. Unfortunately I couldn't adapt...

    Why is the zenith angle distribution of the muons cos2(x) ?

    First of all consider that the Earth's atmosphere is a perfect sphere. The path length for θ=0 is the minimum possible. Also note that there no chance to detect a muon for θ=π/2(for this specific angle the muon would have to travel along the Earth's crust, it would collide and interact with the...

    Investigating Possible Impurities on RBS Spectra of a Rhodium-Silicon System

    I was given a sample, that it is suppossed to be a medium thickness Rhodium on top of an infinite silicon waffer. The experimental RBS spectrum along with the simulation looks like that Apparently, there is another element(or maybe 2) that appear on the experimental spectrum. I am relatively...

    Solving Maxwell's Equations in Laser Cavity | Tips and Troubleshooting

    Hello guys, I've been trying to solve Maxwell's Equations in a laser cavity, with length L. However I cannot... I've searched over the net to find a proper solution but I couldn't. I started by taking a field E(x,y,x,t)=E0 e(x,y)e-jw te-jb z. I take the phasor E(x,y,z)=e(x,y)e-jb z and...

    Why could we see a laser hologram?

    That's correct.However you are missing sth.The laser beam area is about 0.2 cm^2. In order to see the hologram,you need to splay the beam.In this case the ratio Power/Area is far less than before(The hologram's area could be 4 cm^2 in case of a coin or even bigger).Hope I helped a bit!
