Description
A FAZIA (Forward-angle A and Z Identification Array) telescope consists of two silicon pad detectors and a CsI(Tl) scintillator. Using the ΔE–E correlation and pulse shape analysis (PSA), the FAZIA detector can identify charges up to Z = 52 and discriminate isotopes up to Z = 25.
Presently, the FAZIA upgrade project is ongoing with the goal of extending the beam-energy coverage and lowering the particle-identification threshold. Within this project, the Korean FAZIA group is taking a leading role in the development of silicon sensors with various thicknesses and improved Front-End Electronics (FEE) boards. Silicon sensors with thicknesses ranging from 115 to 750 μm have been successfully developed, and their energy resolution has been evaluated using an Am-241 alpha source. The newly designed FEE boards employ the latest Xilinx Kintex-7 FPGA with optimized VHDL firmware.
Recently, the Korean FAZIA group successfully assembled a FAZIA detector block consisting of 16 telescopes using the newly developed 100 μm and 675 μm silicon sensors together with the upgraded FEE boards. To evaluate the performance of the detector block, a proton beam test was performed using the cyclotron at RAON.
This presentation will introduce the current status of the detector development by the Korean FAZIA group and summarize the performance evaluation results obtained from the proton beam test at RAON.
