20140230471 | Compact Cooling System and Method for Accurate Temperature Control - In an integrated two-phase accumulator controlled loop cooling system, the pumped refrigerant is employed to cool the supply of refrigerant in the accumulator vessel. No external cooling of the accumulator vessel is required, and a standard heater in the accumulator is sufficient to regulate the boiling pressure. This allows to provide a cooling system in which sub-cooling in the pump is guaranteed by the laws of nature, and which is hence more reliable, structurally simpler, better to control and cheaper. | 08-21-2014 |

20120264064 | Method for fabricating an amplification gap of an avalanche particle detector - The invention relates to an improved method for fabricating the amplification gap of an avalanche particle detector in which two parallel electrodes are spaced apart by dielectric spacer elements. A foil including a bulk layer made of dielectric material sandwiched by two mutually parallel metallic electrodes is provided, and holes are formed in one of the metallic layers by means of photolithography. The amplification gap is then formed in the bulk layer by means of carefully controlled etching of the bulk material through the holes formed in one of the metallic layers. The invention not only provides a simplified fabrication process, but also results in a detector with enhanced spatial and energy resolution. | 10-18-2012 |
20120261585 | Capacitive Spreading Readout Board - A readout board for use in a micropattern gas detector comprises a plurality of detector pads arranged into a plurality of consecutive layers that are separated by dielectric spacer material. An electron cloud hitting the front side of the readout board will induce a charge on one of the detector pads of the uppermost layer. By capacitive coupling, the signal will propagate downwards through the consecutive layers until it reaches the bottom layer, from which the charges are read out and analyzed. The position of the impact can be determined by comparing the charges that have spread to neighboring readout pads. Since only the bottommost layer of the readout pads needs to be connected to readout electronics, incident particles can be localized at high precision despite the relatively large size of the readout pads in the bottom layer. The invention is effective both in a gas electron multiplier (GEM) and in a MicroMegas detector. | 10-18-2012 |
20120006991 | Method, Apparatus and Computer Program for Measuring the Dose, Dose Rate of Composition of Radiation - A method and an apparatus for measuring the dose, the dose rate and/or the composition of radiation is disclosed. In the method, a detector means is exposed to a radiation environment, the detector means comprising an array of radiation sensing detector elements. The detector means is switched in a sensitive state for the duration of a sensitive time period, and during said sensitive time period, an interaction pattern generated by individual radiation quanta interacting with one or more of the detector elements is recorded. The duration of the sensitive time period can be precisely adapted to the intensity of the radiation that has to be recorded. The interaction pattern is analyzed to distinguish individual radiation quanta received during the sensitive time period, and a radiation category is assigned to each of the distinguished radiation quanta based on its corresponding interaction pattern. A dose, a dose rate and/or a composition of radiation is then computed from the detected and categorized radiation quanta. Weight factors are attributed to each radiation category to take into account the individual degree of damage which the corresponding category can inflict in the irradiated materials. | 01-12-2012 |

20110272591 | Protected readout electrode assembly - The readout electrode assembly of an avalanche particle detector can be effectively protected against sparks and discharges by means of a plurality of resistor pads formed in a dielectric cover layer above the readout pads. The resistor pads may either be connected directly to the readout pads, or may be coupled capacitively by means of a charge spreading pad embedded into the dielectric cover layer and spatially separated from the readout pads. The charge spreading pad allows the distribution of charges to neighboring readout pads, and may hence increase the spatial resolution of the detector device. | 11-10-2011 |
