Abstract: The invention relates to a process for fabricating a high-precision object made of at least one inorganic material, comprising the following steps: using a high-resolution photolithography process, employing X-rays or UV rays depending on the desired degree of precision, in a chosen direction Z, to form a negative mold, which does not deform at the microscale during the steps of the process, in a material able to withstand a step for forming the object by dry deposition and capable of either being removed without altering the object fabricated or being separated from said object; choosing, independently of the normal redox potential of its constituent elements, at least one inorganic material from the set of materials that can be deposited by dry deposition and that allow the object to be fabricated to meet its thermomechanical and environmental specifications; and forming, by means of the non-deformable negative mold, the object to be fabricated by dry deposition of said at least one inorganic material, ther

Abstract: An ionizing radiation detector having an enclosure filled with a rare gas within which is located a proportional counter. An absorption zone is formed between the counter and the upper wall of the enclosure in which radiation is ionized. The counter has at least one anode and at least one cathode which are parallel to one another and separated by an insulating material layer. The cathode and the insulating material layer have at least one opening in which there is a substantially uniform electric field and which constitutes a multiplication zone for electrons which result from the ionization of the radiation.
