An ionizing radiation detector comprises a focusing electrode arranged between an avalanche cathode and anode, and having a hole with an area smaller than the cathode hole but larger than the anode hole. An ionizing radiation detector comprises a chamber filled with ionizable medium, first electrode arrangement(s), and read-out element arrangement(s) (15). The first electrode arrangement is provi...

Loam is extruded through a nozzle to create a first pattern (14) of holes extending through the brick (10), then a second pattern (15) of holes is created close to the back side (12) of the brick. The total area of the holes in the second pattern allows post-treatment of the extruded brick. An Independent claim is also included for bricks produced by this method.
