Fluid cooled trap

A trap through which a gas stream may flow and capable of collecting material created by condensation of a gas or gases in the gas stream while the gas stream is flowing through the trap, said gas stream entering said trap at an initial temperature, comprising:

• a first housing substantially enclosing a primary chamber, said first housing having an entrance through which said gas stream flows into said primary chamber substantially in an initial flow direction, said primary chamber having a first impact surface distinct from said first housing contained within said first housing, said impact surface being positioned at a distance spaced apart from said entrance and shaped such that substantially all of said gas stream entering said primary chamber will either impact and deposit on said first impact surface or be diverted away from said initial flow direction by said impact surface, said distance being substantially empty such that gas flow through said distance is substantially uninterrupted and said primary chamber's capacity for deposition and buildup of condensed solid material in said primary chamber is substantially optimized;
• a second housing substantially enclosing a secondary chamber, said second housing having an inlet in said primary chamber such that said gas stream flows from said primary chamber through said inlet into said secondary chamber and an outlet through which said gas stream exits said second housing and the trap, said inlet and said outlet of said secondary chamber being distinct from said entrance in said first housing, wherein said second housing extends into said primary chamber and said secondary chamber includes a secondary impact surface distinct from said second housing and positioned within said secondary chamber and shaped such that substantially all of the gas stream entering and flowing through the secondary chamber either impacts and deposits on said secondary impact surface or is diverted in gas flow direction by said secondary impact surface, further wherein said secondary chamber includes cooling means connected to said secondary impact surface for maintaining said secondary impact surface at a temperature lower than the initial temperature of said gas stream entering the trap.

A trap for deposition of material in a gas stream having an entrance for the gas stream and an exit for the gas stream, wherein the gas stream enters the trap at an initial temperature and exits the trap at a second temperature, comprising:

• a first housing substantially enclosing a primary chamber and a second housing substantially enclosing a secondary chamber, said first housing having an entrance through which said gas stream flows into said primary chamber substantially in an initial flow direction, said primary chamber having a first impact surface formed by said second housing and positioned such that a substantially unimpeded flow path exists for said gas stream entering said primary chamber through said entrance between said entrance and said first impact surface and positioned transverse to said initial flow direction of said gas stream and shaped to divert substantially all of said gas stream from said gas stream's initial flow direction except for molecules of said gas stream that impact and deposit on said first impact surface;
• a second housing substantially enclosing a secondary chamber, said second housing having an inlet in said primary chamber such that said gas stream flows from said primary chamber through said inlet into said secondary chamber and an outlet through which said gas stream exits said second housing, said inlet and said outlet of said second housing being distinct from said entrance to the trap, wherein said second housing includes a secondary impact surface distinct from said second housing and positioned within said secondary chamber, further wherein said secondary chamber includes a cooling means connected to said secondary impact surface for maintaining said secondary impact surface at a temperature lower than the initial temperature of said gas stream entering the trap and positioned such that said cooling means does not substantially cool said first impact surface.
