Спутник ФКИ. DAMPE. [Редактировать]

DAMPE (Dark Matter Particle Explorer, Wukong) это китайский космический телескоп который должен будет исследовать источники излучения высокоэнергетических гамма и космических лучей, а также осуществлять измерение параметров электронов. Данный аппарат является первым из пяти которые запланировала к созданию китайская академия наук. Основной научной задачей системы будет являться наблюдение за электронами высокой энергии и гамма-лучами с помощью высокой разрешающей способности, а также искать и исследовать частицы темной материи. Космический аппарат будет находиться на солнечно-синхронной орбите и обладать трех летним сроком активного существования. Его масса ориентировочно составляет 1900 кг. Вес полезной нагрузки составит около 1400 кг.  Стоимость спутника составит около 100 млн долл США.

На борт космического аппарата установлены:

  • пластиковые сцинтилляторные детекторы частиц
  • Si-Pin
  • калориметр BGO
  • детектор нейтронов
  • система управления данными 

Спутник DAMPE будет иметь высокую чувствительность и диапазон, а именно:

  • Для электронов и протонов диапазон детектирования составит от 5 GeV до 10 TeV, с разрешающей способностью около 1 процента на 800 GeV.
  • Для космических лучей диапазон составит от 100 GeV до 100 TeV, с разрешающей способностью лучше чем 40 процентов на 800 GeV. Геометрический фактор около 0.3 кв. метров для электронов и фотонов, и около 0.2 квадратных метров для космических лучей. Угловое разрешение составит 0.1 град. на 100 GeV.

Offline and CAD-GEANT4 software of the DAMPE mission Andrii Tykhonov* (for the DAMPE collaboration) Département de physique nucléaire et corpusculaire (DPNC), University of Geneva, Switzerland DAMPE Geometry model Dark Matter Particle Explorer (DAMPE) is a satellite-borne particle detector mission with a launch scheduled for the end of 2015. Detector geometry is implemented in GDML format (Geometry Description Markup Language) and obtained directly from the CAD engineering drawings. Conversion to GDML is done in few steps. First, CAD drawings (.step) are exploded into .stl files, where each file represents one component made of single material: It consists of silicon-tungsten tracker-converter (STK), BGO calorimeter, plastic scintillator serving as anti-coincidence unit and neutron detector. Total thickness of about 30 radiation lengths makes DAMPE the deepest calorimeter in space. Silicon tracker (STK) 6 x and 6 y planes Plastic scintillator Next, each .stl part is converted into GDML using CADMESH [1]. Finally, Sensitive parts are parsed and converted into simple geometries instead of tessellated ones. BGO calorimeter Neutron detector ~30 radiation lengths Reconstruction Detector geometry (geant4): whole (left); sensitive detectors only (right) Software framework Core part of software is written in C++, management part is done in Python (boost-python libraries are used to bridge between two). All algorithms including simulation and reconstruction are inherited from the same base class. Computing jobs are defined via python job option files, while more general settings are stored in the configuration files. Particle reconstruction starts in BGO. Shower direction is propagated to STK, and, if a hit is found in the STK within a certain window, a track seed is formed and filtered further using the adaptation of Kalman technique [2]. An iterative procedure is performed looping over all STK planes looking for different tracks, while “seed” hits of previously reconstructed tracks are removed from the list. Ghost tracks are eliminated: if two tracks are crossing each other, a lower quality track (the one having less hits or lower χ2) is considered as ghost and subsequently removed. At the same time “forks” in the direction towards BGO are kept to allow for photons converting to e+e- pairs. Displays of reconstructed events (beam test at the SPS, CERN): muon (left), electron (middle), photon (right) CONCLUSIONS Highly flexible software framework has been developed for the DAMPE experiment. It features an efficient method for geometry implementation from the CAD engineering drawings, without suffering an overhead of dealing with tessellated solids. Reconstruction software has been successfully tested during the beam test campaigns at CERN and cosmics data taking during the integration tests of the DAMPE satellite.
