Abstract:

The results of an accelerated life time test of neutron irradiated ABB Hafo radiation hard LEDs are presented. After a 1 MeV neutron irradiation with up to 1.4 × 1014 n/cm2 at the Rutherford Appleton Lab (RAL) ISIS facility, the LEDs have been operated without seeing any degradation due to ageing for a time which is estimated to correspond to about 57 years of operation in the ATLAS Semiconductor Tracker (SCT) at the Large Hadron Collider (LHC). The irradiation decreased the light output of the LEDs substantially, but during the operation of the LEDs a fast annealing of most of the irradiation damage was observed.

Abstract:

We report on a search for right-handed W bosons (WR) with mass greater than 200 GeV/c2. We used data collected with the D0 detector at the Fermilab Tevatron pp¯ collider at √s = 1.8 TeV to search for WR decays into an electron and a massive right-handed neutrino WR±→e±NR. Using the inclusive electron data, we set mass limits independent of the NR decay: mWR>650 GeV/c2 and mWR>720 GeV/c2 at the 95% confidence level, valid for mNR<1/2 mWR and mNR≪mWR, respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W’) decaying into eν. In addition, limits on mWR valid for larger values of the NR mass are obtained assuming that NR decays to an electron and two jets. © 1996 The American Physical Society.
