“…The value ∆P i represents the distance from the center of mass to each row of the fitted track. Using Equation (1), the standard error (SE) of the mean value of ∆P for all rows was calculated to be 6.45 µm, and this represents the position resolution of the beam monitor that measured the track [35,36]. According to the data analysis, unsaturated projects were observed at the initial phase of each beam injection, followed by eventually saturated projections.…”

To monitor the position and profile of therapeutic carbon beams in real-time, in this paper, we proposed a system called HiBeam-T. The HiBeam-T is a time projection chamber (TPC) with forty Topmetal-II- CMOS pixel sensors as its readout. Each Topmetal-II- has 72 × 72 pixels with the size of 83 μm × 83 μm. The detector consists of the charge drift region and the charge collection area. The readout electronics comprise three Readout Control Modules and one Clock Synchronization Module. This Hibeam-T has a sensitive area of 20 × 20 cm and can acquire the center of the incident beams. The test with a continuous 80.55 MeV/u 12C6+ beam shows that the measurement resolution to the beam center could reach 6.45 μm for unsaturated beam projections.

“…The Nupix-R1 can simultaneously measure the position, arrival time, and energy deposition of the particle hits. Temporal measurements are crucial for accommodating event rate requirements, whereas energy measurements serve a dual purpose: aiding in achieving heightened temporal resolution calibration and delivering enhanced positional accuracy [7,8]. Also, this sensor can be configured to output only the hit positions, for fast readout and low data volume.…”

The Nupix-R1 is a prototype Monolithic Active Pixel Sensor designed for the Electron-ion collider in China. It consists of 128 rows × 128 columns of square pixels with a pitch of 26.3 µm. Since it is implemented in a 130 nm commercial triple-well process, the in-pixel circuit contains only NMOS transistors. The Nupix-R1 can simultaneously measure the energy, arrival time and position of particle hits. In addition, it can also record only the hit positions with a novel zero-compression scheme to increase the readout speed and reduce the data volume. This paper will discuss the design of the Nupix-R1 sensor.

“…Due to silicon pixel detectors having excellent features such as high position resolution, short response time, and fast reading speed compared to other detectors, the non-interceptive beam monitoring system is gradually being developed and applied based on the silicon pixel detector. We have designed a non-interceptive beam monitoring system named Hi'Beam [6][7][8][9][10]. Figure 1 shows the working principle of the Hi'Beam.…”

This paper describes a silicon pixel sensor for non-interceptive real-time beam monitoring at heavy-ion accelerators. The total size of the sensor is 4 mm × 5 mm. It has 64 (row) × 120 (column) square pixels, each single of which is in the size of 40 μm × 40 μm. With the exposed sensing pad, this sensor can directly collect the charge in the media over the pixels. The in-pixel circuit mainly consists of a low-noise Charge Sensitive Amplifier (CSA) to establish the signal for the energy reconstruction and a discriminator with a Time-to-Amplitude Converter (TAC) for the Time of Arrival (TOA) measurement. The analog signal from each pixel is accessible through time-shared multiplexing over the entire pixel array. This paper will discuss the design of this IMPix-S1 sensor.
