Thomas Tsang (BNL)14.06.18, 09:10Radiation HardnessTalkSiPM lost its performance characteristics when exposed to high dose of neutrons. However, the distinct hallmark of SiPMs, low dark count and excellent photon-number-resolving capability, can be recovered by thermal annealing. Several Hamamatsu and FBK series SiPMs are characterized before and after exposure of up to 1010 neutron/cm2 dosage using a 14 MeV neutron generation source. ...Go to contribution page

Dr. Slawomir Mianowski (National Centre for Nuclear Research)14.06.18, 09:50Radiation HardnessTalkDuring my talk I would like to show and discuss results of evolution of MPPC properties during irradiation by neutrons. Two models of Multi-Pixel Photon Counters: S13360-3050CS and S13360-6050CS from Hamamatsu with different size (3x3 mm$^{-2}$ and 6x6 mm$^{-2}$, respectively) and the same subpixel pitch size (50 $\mu m$) were irradiated by neutrons from two sources: PuBe source with...Go to contribution page

Prof. Daniel Durini Romero (FZ Jülich / INAOE)14.06.18, 10:10Radiation HardnessTalkSmall Angle Neutron Scattering (SANS) technique uses cold or thermal neutrons for investigation of soft and condensed matter. Significant developments in microelectronics enabled the use of scintillation-based pixelated neutron detectors that exploit Silicon Photomultipliers (SiPM) for detecting visible light generated within a scintillator, in our case a 1 mm thick Ce-doped 6Li-glass [1]. We...Go to contribution page

Herr Sean Stoll (BNL)14.06.18, 10:50Radiation HardnessTalkThe effects of radiation damage in SiPMs from gamma rays has been measured and compared with the damage produced by neutrons. SiPMs were exposed to 60Co gamma rays at the Solid State Gamma-Ray Irradiation Facility at Brookhaven National Lab and the Institute for Nuclear Research (Atomki) in Debrecen, Hungary. The gamma ray exposures ranged from 1 krad to more than 1 Mrad and the neutron...Go to contribution page

Prof. Robert Klanner (Hamburg University)14.06.18, 11:10Radiation HardnessTalkSiPMs with 4384 pixels of 15 µm x 15 µm produced by KETEK have been irradiated with reactor neutrons to fluences between 10^9 and 5 10^14 cm-2. After the irradiation C-V, I-V, and current transients with and without pulsed light have been performed at +20°C and –30°C. No annealing, in addition to the annealing during the transport and the measurements, has been applied. Outside of the...Go to contribution page
