Abstract. New Silicon-Gas Pixel Detector (SiGPD) is the result of the further development already proposed Gas-Pixel Detector (GPD). The only disadvantage of GPD was the uncertainty of the particle arriving time. The problem can be solved by additional silicon pixels implementation inside existed electronic chip epitaxial layer during regular chip production. The cost of new Si-Gas Pixel Detector remains practically the same. The new detectors have self-triggering properties and can be used for a first level trigger generation in the particle physics experiments and for many other applications. Gas Pixel Detector − the basis of new detectorGas Pixel Detector (GPD) [1] is a small flat drift chamber with 10 mm thick gas volume and with a large electronic chip with pixel sensors about 100×200 µm2 as anode plane. A mesh is placed in about 50 µm in front of the sensors. Strong electric field between the mesh and anode sensors (~100kV/cm) allows to obtain gas amplification of the order of 10 3 to register every electron crossing the mesh. GPD has the following advantages: -Very low material and relatively cheap structure is combined with good particle track reconstruction.-Time-projection method application and specially developed algorithms allow 3D particle track segment reconstruction with position accuracy of ~30 µm and angle measurement precision better than 0.5°. -Because particle track reconstruction is realized on hardware level within chip electronics, it can be done very fast in about 1 µs if 25 ns readout cycle is used. This performance allows GPD to be used for a first level trigger generation in accelerator experiments.

Abstract. In recent years, developments of gaseous detectors based on a combination of electron multiplication gap in the gas and pixel readout chips as a part of the anode plane (GasPixel detectors) reached a level where they can offer unique opportunities for particle detection. Transition radiation (TR) detectors based on this technology can be one of the possible applications. In this work, measurements of energy spectra and angular distributions of transition radiation photons produced by particles with different gamma factors made with a GridPix detector prototype are presented. The observed results are compared with theoretical predictions.
