Description: Abstract: When using a scanning electron microscope (SEM) equipped with a spectrometer, it is difficult to know if the specimen being observed is in the optimal position to get the best readings from the equipment. Previous data collected by my advisor, the Principal Investigator (PI), and Clarion University (CU) has determined a method of specimen orientation through rotation and tilt of the specimen table to determine its optimal positioning. This was done by constructing a macroscale copy of the equipment found inside a SEM and using it to measure the ratio of the specimen’s projected lengths versus the rotation of the specimen table. To confirm the methodology and interpretations of data developed in previous experiments, new data has been collected to test against previous trials. The newest trial has found evidence in support of previous findings, with similar data being produced. This is an indication that the developed method of orienting a specimen inside a SEM may fill a gap in research dedicated to the use of lab equipment. Suggestions for further research and apparatus redesign will be offered along with the conclusions., Honors Thesis Advisor : Dr. Chunfei Li, PhD.
