[Manufacturing equipment, warning indications for equipment, use of the electron tube]
(1) All equipment incorporating this electron tube must be equipped with safety mechanisms as described
below.
(2) All equipment incorporating this electron tube and their operations manual must include the warning
indications described below to ensure safe operation of the electron tube.
(3) To ensure safe operation of this electron tube, observe the precautions described below.
(4) For any questionable points, consult with CETD before operating this electron tube.
High voltage is supplied to the electron gun section and the ion pump section of this
electron tube.
(1) The main body (body terminal) of this electron tube is used as the circuit return wire
(ground wire).
equipment together with the focusing coil to ensure proper grounding.
(2) Place a cover or cage around the high-voltage section to prevent it from being touched.
(High voltage)
The circuit must be designed so that a switch on the door cuts off high voltage and
discharges the capacitor of the high-voltage section when the cover or cage is opened.
(3) Before replacing or performing maintenance work on the electron tube, be sure to turn
OFF the power switch and discharge all residual charge by touching each electrode of
the electron tube with a ground rod. Pay particular attention to the charge in the
capacitor of the high-voltage section.
Never disable the door switch when the cage is open. At least two workers are
required for replacement or maintenance work to ensure safety. (A person who has
received training in cardiopulmonary resuscitation should be present.)
(4) When connecting / disconnecting the ion pump, be sure to turn OFF the ion pump
Observe the following precautions to prevent exposure to harmful high-frequency
electromagnetic radiation (in particular, to avoid the risk of eye damage) and to prevent
telecommunication devices from being adversely affected:
(1) Never supply high voltage when the high-frequency load (output waveguide) is not
(2) To prevent high-frequency leakage due to connection failure in the high-frequency

(3) Do not modify or remove the high-frequency contact elements such as the gasket of
(4) Evaluation of electromagnetic radiation leakage must be performed with the electron
