#The main safety concern during this procedure is electrical shock as high voltages will be used. Standard high voltage safety precautions should be taken, including checking all equipment for damage and ensuring the equipment is properly connected. | #The main safety concern during this procedure is electrical shock as high voltages(813KeV power supply) will be used.

#The second concern is the integrity of the equipment. Most importantly, the graphite diffraction tube. As indicated in the [http://www-hep.phys.unm.edu/~gold/phys307L/manual.pdf#3.4_Important_precautions lab procedure], the graphite is extremely thin and can be easily punctured by current overload. Use the multimeter to ensure the current stays below the maximum allowed current (0.25mA). Additionally, check the target regularly during the experiment for a red glow, indicative of current overload. | #The second concern is the integrity of the equipment.
