1. The operator can inhale particles while handling the chamber and is advised to
cover the mouth or wear a protective respirator mask with fine filter.
2. The system can also be easily damaged if the electron beam is misplaced or is
allowed to drift out of position.
3. Hot targets can cause burns.
4. While the amount of X-ray escaping the machine should be safe, we do not
have current measurements of the level of exposure. Do not operate this
machine if you could be pregnant.
5. Intense light will be emitted from the evaporation materials. Always use dark
safety goggles when you look in the chamber.
4.3 Operation Rules
1. If an equipment failure while being used, never try to fix the problem by
yourself. Please contact NFF staff.
2. Do not operate equipment unless you are properly trained and approved by
NFF staff.
3. Do not leave an on-going experiment unattended.
4. Do not do the evaporation process over ten minutes per run.
5. Should be at least ten minutes for target cooling after evaporation process.
6. Do not change the e-beam focus of the system.
4.4 Initial system checks
1. Touch screen panel will show the equipment is under high vacuum mode due
to “high vacuum valve, HV” and “cryopump, CP” are ON.
2. Chamber ion gauge pressure reads less than 1.0e-7 Torr on the vacuum gauge
