“…The digital signal processing modules consist of a data delay chain, baseline correction, pile-up rejection, and data processing. The Front-End readout Electronics (FEE) board of CEE-TPC is described in more detail in reference [23]. As shown in figure 6, it comprises 4 SAMPA chips and a high-performance FPGA Xilinx Kintex-7.…”

A miniature prototype of time projection chamber for the cooling storage ring external-target experiment (CEE) at the Heavy Ion Research Facility in Lanzhou (HIRFL) was designed for three-dimensional tracking of charged particles produced in heavy-ion collisions at the target region and for particle identification. The prototype consists of a TPC detector chamber with active volume of 9 cm (height), 10 cm (length) and 10 cm (width), gas electron multiplier (GEM) detector readout and SAMPA-based electronics. This work describes design, track reconstruction method and performance of the prototype. The energy resolution is 11.03% sigma using a 55Fe x-ray source. Using heavy-ion beam of 150 MeV/u Fe, the test results show that the two-dimensional position resolution and drift time resolution of the prototype are better than 400 μm and 20 ns, respectively.
