In this presentation, we will review the evolution of the properties of UFSD sensors produced by different vendors as a function of fluence. We will show the expected working points and time resolution during the HL-LHC lifetime, and we will point out the differences among vendors.

In this presentation we describe the third production of Ultra-Fast
Go to contribution page
Silicon Detectors (UFSD3) by Fondazione Bruno Kessler (FBK) in Trento,
in collaboration with University of Trento and National Institute of
Nuclear Physics (INFN) in Torino.
The new UFSD3 production has been designed in order to study specific
features requested for the future Endcap Timing Layer of CMS at the High... -

This new UFSD batch has been produced on Silicon-on-Silicon Epitaxial and Float Zone wafers, with an active thickness of 50µm.
One of the target of the UFSD3 production is the... -

Deep diffused avalanche photodiodes are studied as timing detectors for minimum ionizing particles. This application does not require a radiator to generate light to be detected by the APD. The signal is generated and amplified within the APD bulk.

This new production features pads and strips arrays with 4 different strategies of the gain implant termination, ranging from an inactive area comparable to UFSD2 production to a configuration with a much narrower width. This choice allows studying the impact of the... -

Using a nuclear microprobe, with a lateral resolution of a few micrometers, we have analyzed the CCE homogeneity of the sensor and the behavior of the peripheral regions under proton irradiation. We will show the gain curve... -

Transient Current Technique (TCT). The sensors are irradiated to a fluence of $10^{14}$ $\mathrm{n_{eq}}$/$\mathrm{cm}^2$. For different annealing times (at 60°C), the collected charge, the gain and the
electric field profile is measured. -

A silicon 3D detector with a single cell of 50x50 um2 was produced and evaluated for timing applications. The measurements of time resolution were performed for 90Sr electrons with dedicated electronics used also for determing timing resolution of Low Gain Avalanche Detectors (LGADs). The measurements were compared to those in LGAD and also simulations. The studies showed that the
