Document Summary
Laboratory cautions: the energy from the rf amplifier can can cause burns or even be lethal. Be aware of all electrical connections to the output of this device. Make sure all connections are correct before turning on the amplifier: prolonged exposure to rf radiation may be harmful. Make sure the quartz end flange is screened: the bottom of the diffusion pump is hot and can cause serious burns, do not touch the magnet coil conductors while they are operating, watch water condensation and electricity. Make sure all electrical cords and devices are kept dry: while the magnets are in operation, all magnetic materials should be clear of the machine. The strong magnetic field might throw metal objects: do not touch the rf antenna/plasma source. This is a delicate device and should not be tampered with: do not leave the controlled leak valve open when the vessel is not being evacuated. There is no over-pressure release valve on the vessel.
