“…In total, 40 detectors are placed in the simulation, and the detector geometry is prepared with Geometry Description Markup Language (GDML) [11] format. In total, 40 detector modules are mounted in radial direction like vanes in the experiment [12]. The σ of the distribution is set to be 190/ √ 12 = 54 µm, and the hit points are reconstructed by calculating the middle points of the information from both sides of the detector.…”

“…When a bunch of the muon decays in the storage area, some positrons arrive at the detectors at the same time and in the same place, which is piled up. The pile-up time can be limited to be distinguished from each other due to the limitation of the readout system [12], and ω a is shifted by this effect. Second, the shifted ω a due Sources Description Timing shift due to pile-up Timing shift effects due to the piling up events.…”

The J-PARC muon g-2/EDM experiment aims to measure the muon magnetic moment anomaly a µ = (g − 2)/2 . The target sensitivity for a µ is a statistical uncertainty of 450 × 10 −9 , and a µ can be extracted by measuring the spin precession of muons (ω a ). The ω a can be extracted from the distribution of muon decay time, and the time is measured by reconstructing tracks of positrons which are decayed from the muons. To extract ω a precisely, the systematic effects on ω a should be controlled under the aforementioned sensitivity.To study systematic effects, we develop a compact simulation package, and using our developed package, we study several systematic effects and discuss results. We discuss the package details and studies of systematic effects on ω a based on our package.

“…The sensor capacitance is approximately 17 pF, and the total detector capacitance C det seen from an input of the ASIC is estimated to be less than 30 pF. This value includes the parasitic capacitance coming from flexible printed circuits (FPCs) [7], which connect strip sensors with ASICs. Since the maximum wiring length inside the FPCs is about 250 mm, the parasitic capacitance from the FPCs is not negligible.…”

A new silicon-strip readout chip named "SliT" has been developed for the measurement of the muon anomalous magnetic moment and electric dipole moment (EDM) of the muon at Japan Proton Accelerator Research Complex (J-PARC). The SliT chip is designed in the Silterra 180-nm CMOS technology with mixed-signal integrated circuits. An analog circuit incorporates a conventional charge-sensitive amplifier, shaping amplifiers, and two distinct discriminators for each of the 128 identical channels. A digital part includes storage memories, an event building block, a serializer, and low voltage differential signaling (LVDS) drivers. A distinct feature of the SliT is utilization of the zero-crossing architecture, which consists of a CR-RC filter followed by a CR circuit as a voltage differentiator. This architecture allows generating hit signals with subnanosecond amplitude-independent time walk, which is the primary requirement for the experiment. The test results show a time walk of 0.38 ± 0.16 ns between 0.5 and 3 MIP signals. The equivalent noise charge is 1547 ± 75 e − (rms) at C det = 33 pF as a strip-sensor capacitance. SliT128C satisfies all requirements of the J-PARC muon g − 2/EDM experiment.
