Currently, it is extremely difficult to align the excitation laser pulse with the electron beam inside the microscope. The goal of this project is to develop a method to mon- itor alignment of the two beams to roughly 10-\u0152\u00bam resolution and to measure the spatial profile and intensity of the laser pulse at the sample plane. To this end, the ÎÞÓÇÊÓƵ Clinic team created two design alternatives: the sensor-in-vacuum design and the borescope-phosphor design. The first design uses a sensor directly in the beam path to image the beams, while the second design uses a borescope to image the glow of a phosphor excited by the beams. The team pursued both designs and tabled the sensor-in-vacuum design given the time constraint of the project. The team further pursued the borescope- phosphor design and, after thorough testing, made a final prototype that successfully images a laser profile.<\/p>\n<p id=\"clinic-advisor\"><strong>Advisor(s):<\/strong> Peter N.
