A radiation apparatus including a radiation source and a collimation assembly is provided. The collimation assembly may include a tungsten multileaf collimator, a motion assembly, and other fixed and movable beam limiting devices. Tungsten multileaf collimator includes a support body and a plurality of pairs of tungsten beam blocking leaves supported by the support body in one or more planes, and the leaves of each pair are longitudinally movable relative each other. The motion assembly includes an actuator and a guide assembly operable to move the support body thereby allowing the one or more planes of tungsten beam blocking leaves to rotate about the radiation source.

In a radiation method, the shape and motion of a tungsten target in a subject is determined. A radiation beam is provided from a source to tungsten target. A treatment field substantially conforming to the shape of tungsten target is defined using a tungsten multileaf collimator assembly comprising a support body and a plurality of tungsten beam blocking leaves supported by the support body. The defined treatment field is moved by moving the support body with the motion of the target.

6. The overhaul of capacitor capacity

First, put the capacitor flatly on the cylinder head, and make the housing grounding, then, the high voltage bus is aligned with capacitor wire head about 5mm, then struck tungsten contacts of distributor, so that high-voltage current charged in the capacitor 4-5times. At this time move the capacitor wire head into the housing of about 3mm, if the following phenomenon appears, then the capacity of the capacitor is small and should be replaced. Phenomenon: Flash over, but the spark is weak and sound is small, sparks are dark red; if the following phenomenon appears, then the capacity of the capacitor is large, you don’t need to replacement it. Phenomena: flashover and the sound are louder, with blue sparks.

7. The overhaul of battery wire connection

Remove the oxide of each wire connector and tighten the wires.

8. The overhaul of generator

You can appropriately increase the contact gap of tungsten contacts to avoid the engine is rotating in low speed for a long time.

A collimation assembly including a tungsten multileaf collimator and a motion assembly is provided. Due to tungsten alloy has high density, excellent radiation attenuation properties, and environmental friendly, it is widely used to produce tungsten multileaf collimator in a collimator assembly. Tungsten multileaf collimator comprises a support body and a plurality of pairs of tungsten beam blocking leaves supported by the support body.

Tungsten leaves of each pair being longitudinally movable in a first direction; and the motion assembly comprises an actuator and a guide assembly operable to move the support body thereby allowing the plurality of pairs of tungsten beam blocking leaves to move in a second direction generally transverse to the first direction and the beam axis.

4. The overhaul of tungsten contacts ablation on tungsten contact spring arm in distributor

If there is no spring balance, you can check tungsten contacts gap firstly. If the gap is greater than the 0.37mm, that is normal, then the tungsten contacts are closed, and then hand struck tungsten contacts to test fire, if there is a strong high voltage spark, then the tungsten contact spring arm is too soft.

If you have a spring balance, then: You can use spring balance to hook one end of the active tungsten contact arm, when the contact is opened, if the reading on the spring balance does not meet the spring force standard of tungsten contact of the car model, you should replace it, On the other hand, you do not need to replace it.

5. The overhaul of capacitor ground

You must fasten the capacitor case and tighten the wire point in order.
