The simplest method uses one or more pulsed deflecting dipole magnets ( injection kicker magnets ) to steer an incoming train of particles onto the stored beam path; the kicker magnets are turned off before the stored train returns to the injection point, thus resulting in a stored beam.

A tree often provides numerous additional functions including chemical injection points, well intervention means, pressure relief means, monitoring points ( such as pressure, temperature, corrosion, erosion, sand detection, flow rate, flow composition, valve and choke position feedback ), and connection points for devices such as down hole pressure and temperature transducers ( DHPT ).

With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30-50 ppb . " Common injection points are just after the condensate polisher and again at the deaerator outlet . " This forms a thicker protective layer of hematite ( Fe 2 O 3 ) on top of the magnetite.

One popular configuration for the mixing tube is a large bore tube with a series of internal baffles which create turbulence in the mixture after the injection point, which causes fairly rapid mixing to a homogenous mixture, which may then be continuously analysed by a monitoring instrument before further processing, or may be directly processed and analysed later from the storage cylinder.
