6. OPERATING AND MAINTENANCE INSTRUCTIONS
6.1. Installing an E3730A klystron
6.1.1. General
6.1.1.1. Equipment-room preparation
Installation of the klystron requires the use of an appropriate handling system. Most
recommended is a system consisting of a rail, fastened to the ceiling, upon which moves a hoist,
whose hook when fully raised must be at least 2 meters above the electromagnet and 3 meters
above the oil-tank plate supporting the electromagnet. When unpacking the klystron from the crate,
the hook must be at least 4 meters above the floor where the crate is placed. The rail must have a
length and a disposition such that it is possible to move the klystron from its maintenance cart to
above the electromagnet.
6.1.1.2. Accessories necessary for the installation
One VT-68922 Electromagnet
One VT-69240 series Ion pump high voltage power supply
One VT-69045 Output flange copper gasket
One VT-69064 X-ray shield kit
(VT-69063 :X-ray shield kit is factory furnished)
One VT-69065 Lifting attachment
Bolts described in this chapter
One thermocouple monitoring for electromagnet
6.1.2. Unpacking the klystron
First of all, the klystron with its X-ray shielding lead blocks is so heavy more than 280kg,
lifting or supporting the klystron by hands is dangerous and must be strictly forbidden. Lifting
devices such as hoists are necessary. Checking all the lifting devices must be taken before
unpacking or installing the klystron.
The klystron is packaged in double crates with cushions between them. The crates and the
klystron will be freighted in vertical position.
Unpack the outer crate and then remove the cushions on the inner crate. Lift up the inner
crate from the outer crate and move to an open space to stand up the crate in vertical position
securely. Remove the top and front lids from the inner crate.
Fasten the klystron lifting attachment at the collector shielding bracket. Remove "collar" half
board on top of shielding bracket side and the electron gun side, and six pairs of fixing bolts and
nuts (M12) from the collector pole-piece. Lift the klystron several centimeters up, then remove
"collar" half board below the collector pole piece and slowly move the klystron off from the crate in
horizontal direction.
