		removed, make sure to first turn off all power to the instrument.

Electron Gun / Ion pump Baking

•The electron gun and ion pump are heated to about 250°C in order to keep the electron gun in a high vacuum. Touching these sections would result in burns.

Beware of high
	Rotary Pump
temperature
	•	The temperature of the oil rotary pump rises up to about 70°C, while it
		is operating. Touching the pump may also result in burns.
	Liquid Nitrogen
	•	When you replenish liquid nitrogen in the cold-trap of DP and the
		anti-contamination trap, be sure to wear eye-protection glasses and
Beware of low		protective gloves to keep liquid nitrogen from splashing on the eyes or
		the skin.

•Anyone working on the electrical part of the system should follow the correct lock-out tag-out procedures for that location.

•The user should prepare a mains switch box on which the lock-out and the tag-out procedures are provided.

•Electrical hazards can occur if lock-out tag-out procedures are not followed.

•The ion-pump produces magnetic fields. There are fringing magnetic fields of about 100 Gauss from the ion-pump and 10 Gauss at the outside of the ion-pump cover.

Any person who has a pacemaker embedded is not allowed to approach the ion-pump.

Do not bring near to the ion-pump wristwatches and magnetic cards that are susceptible to magnetic fields.
