“…A classic example is the difference between the readout electronics in the ALICE experiment's TRD, which adopts a slow readout method, and those in the ATLAS experiment, which, due to high collision luminosity, requires a fast readout system. TRDs used for measuring TR emission angles require electronics with two-dimensional readout capabilities, such as those utilizing the Timepix3 chip-based readout for TRD [443].…”

Abstract“A Craftsman Must Sharpen His Tools to Do His Job,” said Confucius. Nuclear detection and readout techniques are the foundation of particle physics, nuclear physics, and particle astrophysics to reveal the nature of the universe. Also, they are being increasingly used in other disciplines like nuclear power generation, life sciences, environmental sciences, medical sciences, etc. The article reviews the short history, recent development, and trend of nuclear detection and readout techniques, covering Semiconductor Detector, Gaseous Detector, Scintillation Detector, Cherenkov Detector, Transition Radiation Detector, and Readout Techniques. By explaining the principle and using examples, we hope to help the interested reader underst and this research field and bring exciting information to the community.

“…A possible application for the prototype TPC chamber proposed here is the high luminosity e + p collision as EIC, where the collision rate is high and thus continuous readout is a necessity. In table 2, the track density and the space charge impact to tracking in a TPC acceptance are listed for different collisions based on EIC projection and achieved luminosities at RHIC/STAR [9,20]. We can see that, although collision rate is high enough at EIC, but the track multiplicity is smaller than p + p and significantly lower than A + A collisions.…”

“…20µm diameter gold-plated tungsten wires with a tension of 0.5 Newton were used [8]. Then two 10cm×10cm standard GEM foils [9] were mounted above the anode plane, with a pitch of 140µm, 70µm outside diameter, 50µm internal diameter, 50µm kapton thickness, and 5µm copper thickness on both sides. A 10cm×10cm copper sheet with thickness of 50µm is used as the drift plane.…”

Gated wires are widely used in Time Projection Chamber (TPC) to avoid ion back-flow (IBF) in the drift volume. The anode wires can provide stable gain at high voltage with a long lifetime. However, switching on and off the gated grid (GG) leads to a dead time and also limit the readout efficiency of the TPC. Gas Electron Multiplier (GEM) foil provides a possibility of continuous readout for TPC, which can suppress IBF efficiently while keeping stable gain. A prototype chamber including two layers of GEM foils and anode wires has been built to combine both advantages from GEM and anode wire. Using Garfield++ and the finite element analysis (FEA) method, simulations of the transmission processes of electrons and ions are performed and results on absorption ratio of ions, gain and IBF ratio are obtained. The optimized parameters from simulation are then applied to the prototype chamber to test the IBF and other performances. Both GEM foils are run at low voltage (255V), while most of the gain is provided by the anode wire. The measurement shows that the IBF ratio can be suppressed to ∼0.58% with double-layer GEM foils (staggered) at an effective gain about 2500 with an energy resolution about 10%.

To address complexities arising from the increased number of readout channels in large scale neutron detection or imaging systems, a multiplexing readout method is introduced. The proposed method can greatly reduce the scale and cost of the readout electronics. To evaluate the readout method, a prototype involving a front-end circuit and a signal multiplexed circuit for detectors such as multiwire proportional chamber (MWPC), gaseous electron multipliers (GEM) and micro-channel plates (MCP) is evaluated in the laboratory. The multiplexing circuit consists of a switch array and a high speed analog to digital converter (ADC). By controlling the switch timing, multi-channel signals can be readout through only one ADC channel, thereby reducing the number of channels required for readout. Furthermore, the readout speed can be adjusted by changing the switching frequency. The results show that the multiplexing readout method is feasible, and the position resolution for thermal neutron detectors is good. The evaluation board is used to simulate the MWPC detector with 2 mm spacing and a position resolution of 35 µm is obtained with event rate up to 2 MHz. Besides, joint test with a thick gaseous electron multipliers (TGEM) detector with 0.8 mm spacing yields a position resolution of about 400 µm.
