Description:
A multi-coolant or refrigerated type baffle is
normally employed as a primary or secondary baffle to reduce
backstreaming above diffusion pumps. Its principal function is to
condense vapors coming from the system or from the diffusion pump, and
when used in conjunction with properly designed intermediate baffling,
to condense vapors from the system above, thus acting as a pump to
achieve an ultra-high vacuum. In addition to condensing, or trapping
vapors, the baffle must allow non-condensable gases to move through it
with as little impedance as possible. To do this, the baffling
must be optically dense and so constructed, that any molecule entering
from the system in any direction will strike a chilled surface.
This criterion for multi-coolant baffles is achieved in the shrouded
herringbone design of the DMC series. This combination of a
refrigerated shroud and the herringbone fins produces a high conductance
baffle while still maintaining the ability to condense the majority of
the condensable vapors.
Although the DMC series baffles may be used directly above most
diffusion pumps, it is preferable to use either a water-cooled or
ambient baffle between the DMC multi-coolant baffle and the diffusion
pump. This combination reduces the heat radiated from the system
thus reducing the consumption of the refrigerant. A water baffle
may be included in the trap itself or separately fitted with a DAB
series baffle.
