Speed Of Light Partner: Alex Andrego Equipment Safety Before we begin, some points of safety must be noted: First and foremost your safety comes first and then the equipments' Check the cords, cables, and machinery in use for any damage or possible electrocution points on fuses of machinery by making sure the power cords' protective grounding conductor must be connected to ground Be careful when handling the photomultiplier tube (PMT) (it can be ruined in ambient light when at operating voltages) Be careful when handling the Harrison Laboratories 6207A Power Supply when the capacitor plates are fully charged, even when unplugged wait for it to discharge for it may be a source of electrical shock Make sure the areas containing and around the experiment are clear of obstacles Purpose The Ratio e/m for Electrons Brief Description of e/m ratio Setup & Procedure Note: Alex and I used the same set up and procedure. This is a direct copy of it.
