“…If one wants to stack multiple conversion layers, they need to be interleaved with fast detectors of lower Z and it deteriorates the performances of the system. An alternative could be the implementation of an active conversion layer using fast and thin silicon detectors [8].…”

The quest for µ → eγ is one of the most important endeavors to search for New Physics beyond the Standard Model. In this talk I will review the current status of the experimental searches by the MEG Collaboration at PSI. I will also present a study of the experimental limiting factors that will define the ultimate performances, and hence the sensitivity, in the search for µ → eγ with continuous muon beams of extremely high rate (one or even two orders of magnitude larger than the present beams), whose construction is under consideration for the next decade.

Gain and time resolution of 45 μm thin Low Gain Avalanche Detectors before and after irradiation up to a fluence of 10¹⁵n_eq/cm²

A : Low Gain Avalanche Detectors (LGADs) are silicon sensors with a built-in charge multiplication layer providing a gain of typically 10 to 50. Due to the combination of high signal-to-noise ratio and short rise time, thin LGADs provide good time resolutions.LGADs with an active thickness of about 45 µm were produced at CNM Barcelona. Their gains and time resolutions were studied in beam tests for two different multiplication layer implantation doses, as well as before and after irradiation with neutrons up to 10 15 n eq /cm 2 .The gain showed the expected decrease at a fixed voltage for a lower initial implantation dose, as well as for a higher fluence due to effective acceptor removal in the multiplication layer. Time resolutions below 30 ps were obtained at the highest applied voltages for both implantation doses before irradiation. Also after an intermediate fluence of 3 × 10 14 n eq /cm 2 , similar values were measured since a higher applicable reverse bias voltage could recover most of the pre-irradiation gain. At 10 15 n eq /cm 2 , the time resolution at the maximum applicable voltage of 620 V during the beam test was measured to be 57 ps since the voltage stability was not good enough to compensate for the gain layer loss. The time resolutions were found to follow approximately a universal function of gain for all implantation doses and fluences.

“…According to our simulations, a single layer with the specifications in [28] (100 µm silicon on top of 50 µm Kapton) would give a negligible contribution to the E γ resolution. For a 4-layer system, which would give a 50 ps resolution, comparable with the timing performances of the MEG-II LXe calorimeter, this contribution would be ∼ 300 keV, i.e.…”

“…An R&D activity is ongoing (TT-PET project [27,28]) to realize a thin monolithic detector (100-300 µm) in a Si-Ge Bi-CMOS process, that contains both the silicon sensor and the frontend electronics, featuring less than 100 ps time resolution for minimum ionizing particles. A dedicated design could be adopted in the μ + → e + γ application, by stacking multiple detector layers in order to improve the resolution accordingly.…”

The quest for $$\mu \rightarrow e \gamma $$ μ → e γ and its experimental limiting factors at future high intensity muon beams

et al. 2018

The search for the lepton flavor violating decay μ + → e + γ will reach an unprecedented level of sensitivity within the next five years thanks to the MEG-II experiment. This experiment will take data at the Paul Scherrer Institut where continuous muon beams are delivered at a rate of about 10 8 muons per second. On the same time scale, accelerator upgrades are expected in various facilities, making it feasible to have continuous beams with an intensity of 10 9 or even 10 10 muons per second. We investigate the experimental limiting factors that will define the ultimate performances, and hence the sensitivity, in the search for μ + → e + γ with a continuous beam at these extremely high rates. We then consider some conceptual detector designs and evaluate the corresponding sensitivity as a function of the beam intensity.
