Performance of TPC detector prototype integrated with UV laser tracks for the circular collider
Abstract
Several new experimental concepts in high-energy particle physics have been proposed in recent years. The physical goals include precisely measuring the properties of particles such as Higgs, Z and W, and even looking for signs of new physics at future colliders. To meet the evolving requirements for particle track detector, Time Projection Chamber (TPC) detector prototype integrated with a UV laser track system was developed for the main track detector at Circular Electron Positron Collider (CEPC). This prototype consists of 6 horizontal laser tracks around TPC detector chamber, a fast electronics readout of 1280 channels, a GEM detector with 200 × 200mm2 active area, and the DAQ system. The hit resolution, dE/dx resolution and drift velocity were studied by measuring and analyzing using the TPC prototype and UV laser tracks. The dE/dx resolution of the prototype was measured to be (8 . 9 ± 0 . 4) % . Extrapolating this to CEPC TPC with 220 layers and longer track, the resolution was estimated to be (3 . 36 ± 0 . 26) % . All results indicated that the TPC detector prototype integrated with UV laser tracks can work well.
