The Stanford Synchrotron Radiation Light accelerates electrons around a 234-meter circumference ring at relativistic speeds. The x-ray radiation produced by this process is used in many fields of science ranging from materials science to medicine.
This project seeks to measure the polarization of the 532 nanometer wavelength component in the visible light beam emitted from the SPEAR-3 synchrotron as a function of vertical position. The beam was focused through a lens, then passed through a 532 nm band pass filter and a polarizer mounted on a rotating stand. The beam power was measured as a function of vertical position and …

Abstract
Research to determine basic molecular properties utilizing pump/probe experiments is an on going effort at SLAC. Here we have been given the task to generate mid-IR laser pulses and commission a mid-IR detector for said experiments and research. The mid-IR pulses will be used to probe the changes in molecular properties induced by exciting the electrons in molecules with visible pump pulses. In order to accomplish this, an optical parametric amplifier (OPA) has been set-up and aligned. The pump beam for the OPA is a 40 femtosecond 800nm …
