My Senior Thesis is DONE

After hundreds of hours of machining, wiring, troubleshooting, programming, fiddling, head scratching, fixing, typing, agonizing, and banging my head against the optical table...

It's done! And aaaaalllliiiiiiivvve!

My senior thesis. (<--- see that period? My thesis is as done as that period! Uhmph!) ..... I just noticed a typo.

Controlled Attenuation of Laser-generated High-order Harmonics for Extreme Ultraviolet Polarimetry

We constructed an extreme ultraviolet (EUV) polarimeter which utilizes laser- induced high harmonics as the light source. This device is capable of making absolute reflectance measurements as low as 0.2% over a wavelength range of 8-89 nm. The polarimetry positioning system allows incident reflectance angles of 0–40◦. In order to increase the dynamic range of our EUV detector we introduced a low-pressure gas downstream from the harmonic generation region to predictably attenuate EUV flux during incident measurements. We also used the gas cell to measure the photoabsorption cross sections of hydro- gen and oxygen compared to that of water vapor, revealing the influence of chemical bonds on EUV absorption.

If you still wanna read it, then click here (.pdf) . It has pretty pictures, I promise!

Good to know that your senior thesis was finished! I think the hundred of hour you spent on it really give you the thesis help you needed to complete this project. Well, if you really determine to do something, then it just right to spend time and effort on it.
