Abstract

In one embodiment, a device for capturing radiation includes: a panel defining a plurality of double wedge chambers, wherein each double wedge chamber includes a first wedge-shaped chamber that tapers into an opening for a second wedge-shaped chamber, and wherein a longitudinal axis of the first wedge-shaped chamber is not collinear with a longitudinal axis of the second wedge-shaped chamber.

1 . A device for capturing radiation, comprising:
 a panel defining a plurality of double wedge chambers, wherein each double wedge chamber includes a first wedge-shaped chamber that tapers into an opening for a second wedge-shaped chamber, and wherein a longitudinal axis of the first wedge-shaped chamber is not collinear with a longitudinal axis of the second wedge-shaped chamber.   
   
   
       2 . The device of  claim 1 , wherein the plurality of double wedge chambers extend in parallel linear rows on the panel. 
   
   
       3 . The device of  claim 1 , wherein for each the longitudinal axis of the second wedge-shaped chamber is tilted with respect to the longitudinal axis of the first wedge-shaped chamber. 
   
   
       4 . The device of  claim 1 , wherein the first and second wedge-shaped chambers for each double wedge chamber are coated with a radiation-absorbing coating. 
   
   
       5 . The device of  claim 1 , wherein the panel is a planar panel. 
   
   
       6 . The device of  claim 1 , wherein the panel is a non-planar panel. 
   
   
       7 . The device of  claim 1 , wherein the second wedge-shaped chamber for each double wedge chamber terminates at a vertex. 
   
   
       8 . The device of  claim 1 , wherein the first wedge-shaped chamber for each double wedge chamber includes a first face and a second face that define a first angle, and wherein the second wedge-shaped chamber for each double wedge chamber includes a third face and a fourth face that define a second angle. 
   
   
       9 . The device of  claim 8 , wherein the first angle is around 28° and the second angle is around 15°. 
   
   
       10 . The device of  claim 8 , wherein the first angle is around 32° and the second angle is around 15°. 
   
   
       11 . A method of manufacturing a device, comprising:
 providing a die having an aperture that defines a plurality of double wedge chambers, each double wedge chamber including a first wedge-shaped chamber that tapers into an opening for a second wedge-shaped chamber; and   extruding a metal through the aperture in the die to form an extruded metal structure that includes the plurality of double wedge chambers.   
   
   
       12 . The method of  claim 11 , further comprising:
 coating the double wedge chambers of the extruded metal structure with an absorptive coating.   
   
   
       13 . The method of  claim 12 , wherein the coating is selected from the group consisting of Ebonol C, tungsten, tungsten carbide, silicon carbide, black chrome, and black oxide. 
   
   
       14 . The method of  claim 11 , wherein the metal is selected from the group consisting of copper and aluminum. 
   
   
       15 . A device for capturing radiation, comprising:
 a panel that defines a plurality of chambers arranged in parallel; wherein each chamber comprises a first wedge-shaped chamber having an open end that tapers to a truncated second end along a first axis and a second wedge-shaped chamber having an open first end in communication with the truncated second end of the first wedge-shaped chamber, the second wedge-shaped chamber tapering to a vertex along a second axis that is not collinear with the first axis.   
   
   
       16 . The device of  claim 15 , wherein each first wedge-shaped chamber includes a first and a second face that define a first angle, and wherein each second wedge-shaped chamber includes a third and a fourth face that define a second angle. 
   
   
       17 . The device of  claim 16 , wherein the first, second, third, and fourth faces are coated with a radiation-absorbent coating. 
   
   
       18 . The device of  claim 17 , wherein the radiation-absorbent coating is selected from the group consisting of Ebonol C, tungsten, tungsten carbide, silicon carbide, black chrome, and black oxide. 
   
   
       19 . The device of  claim 16 , wherein the first angle is around 28° and the second angle is around 15°. 
   
   
       20 . The device of  claim 16 , wherein the first angle is around 32° and the second angle is around 15°. 
   
   
       21 . The device of  claim 16 , wherein the panel is a metallic planar panel.
