We have developed a custom amplifier board coupled to large-format 16-channel Hamamatsu silicon photomultiplier device for use as the light sensor electromagnetic calorimeters in Muon g-2 experiment at Fermilab. The calorimeter absorber is an array of lead-fluoride crystals, which produces short-duration Cherenkov light. detector sits high magnetic field muon storage ring. SiPMs selected, and their accompanying electronics, must preserve short pulse shape, quantum efficiency, be...
The anomalous magnetic moment of the muon is one most precisely measured quantities in experimental particle physics. Its latest measurement at Brookhaven National Laboratory deviates from Standard Model expectation by approximately 3.5 standard deviations. goal new experiment, E989, now under construction Fermilab, a fourfold improvement precision. Here, we discuss details future and its current status.
The Muon $g-2$ experiment, E989, is currently taking data at Fermilab with the aim of reducing experimental error on muon anomaly by a factor four and possibly clarifying current discrepancy theoretical prediction. A central component this four-fold improvement in precision laser calibration system calorimeters, which has to monitor gain variations photo-sensors 0.04\% short-term ($\sim 1\,$ms). This about one order magnitude better than what ever been achieved for particle physics...
We present the design of a new MicroTCA-based waveform digitizer, which will be deployed in Muon g-2 experiment at Fermilab and allow our pileup identification requirement to met. This digitizer features five independent channels, each with 12-bit, 800-MSPS digitization 1-Gbit memory buffer. The data storage readout along configuration are handled by six Xilinx Kintex-7 FPGAs. In addition, is equipped mezzanine card for analog signal conditioning prior digitization, further widening its...
