The properties of 60-{\mu}m thick Ultra-Fast Silicon Detectors (UFSD) detectors manufactured by Fondazione Bruno Kessler (FBK), Trento (Italy) were tested before and after irradiation with minimum ionizing particles (MIPs) from a 90Sr \b{eta}-source . This FBK production, called UFSD2, has UFSDs with gain layer made of Boron, Boron low-diffusion, Gallium, Carbonated Boron and Carbonated. [...]

We report results from the testing of 35 {\mu}m thick Ultra-Fast Silicon Detectors (UFSD produced by Hamamatsu Photonics (HPK), Japan and the comparison of these new results to data reported before on 50 {\mu}m thick UFSD produced by HPK. The 35 {\mu}m thick sensors were irradiated with neutrons to fluences of 0, 1*10^14, 1*10^15, 3*10^15, 6*10^15 neq/cm^2. [...]

Radiation Hardness of Thin Low Gain Avalanche Detectors
/ Kramberger, G. (Stefan Inst., Ljubljana) ; Carulla, M. (Barcelona, Inst. Microelectron.) ; Cavallaro, E. (Barcelona, IFAE) ; Cindro, V. (Stefan Inst., Ljubljana) ; Flores, D. (Barcelona, Inst. Microelectron.) ; Galloway, Z. (UC, Santa Cruz, Inst. Part. Phys.) ; Grinstein, S. (Barcelona, IFAE ; ICREA, Barcelona) ; Hidalgo, S. (Barcelona, Inst. Microelectron.) ; Fadeyev, V. (UC, Santa Cruz, Inst. Part. Phys.) ; Lange, J. (Barcelona, IFAE) et al.
Low Gain Avalanche Detectors (LGAD) are based on a n++-p+-p-p++ structure where an appropriate doping of the multiplication layer (p+) leads to high enough electric fields for impact ionization. Gain factors of few tens in charge significantly improve the resolution of timing measurements, particularly for thin detectors, where the timing performance was shown to be limited by Landau fluctuations.

For the high luminosity upgrade of the LHC at CERN, ATLAS is considering the addition of a High Granularity Timing Detector (HGTD) in front of the end cap and forward calorimeters at |z| = 3.5 m and covering the region 2.4 < |{\eta}| < 4 to help reducing the effect of pile-up. The chosen sensors are arrays of 50 {\mu}m thin Low Gain Avalanche Detectors (LGAD). [...]

In this paper we report on the timing resolution of the first production of 50 micro-meter thick Ultra-Fast Silicon Detectors (UFSD) as obtained in a beam test with pions of 180 GeV/c momentum. UFSD are based on the Low-Gain Avalanche Detectors (LGAD) design, employing n-on-p silicon sensors with internal charge multiplication due to the presence of a thin, low-resistivity diffusion layer below the junction.
