Small, open ended, parylene cylinders of 150 {mu}m diameter, 250 {mu}m length and 10 {mu}m wall thickness are manufactured and filled with solutions of acrylate monomers which are polymerised {ital in} {ital situ} with {ital uv} light to produce gels. These gels are then precipitated in a non-solvent such as methanol and dried in a critical point drying apparatus to produce foam-filled parylene cylinders for use in laser-driven plasma experiments. The foams have densities in the range of 20 to 200 mg cm{sup {minus}3} and cell sizes of up to 1 {mu}m, fill the cylinders completely, do not shrink during the drying process and do not require subsequent machining.
