a b s t r a c tIn this paper we describe the development and first tests of a neutron spectrometer designed for high flux environments, such as the ones found in fast nuclear reactors. The spectrometer is based on the conversion of neutrons impinging on 6 Li into α and t whose total energy comprises the initial neutron energy and the reaction Q-value. The 6 LiF layer is sandwiched between two CVD diamond detectors, which measure the two reaction products in coincidence. The spectrometer was calibrated at two neutron energies in well known thermal and 3 MeV neutron fluxes. The measured neutron detection efficiency varies from 4:2 Â 10 À 4 to 3:5 Â 10 À 8 for thermal and 3 MeV neutrons, respectively. These values are in agreement with Geant4 simulations and close to simple estimates based on the knowledge of the 6 Li(n,α)t cross-section. The energy resolution of the spectrometer was found to be better than 100 keV when using 2.5 or 5 m cables between the detector and the preamplifiers.

“…N the need for radiation-hard tracking detectors in forthcoming elementary particle physics experiments, silicon is regarded to be the best choice as sensor material because of its unsurpassed material quality, mature technology and low cost for mass production [1]. Recently, a luminosity upgrade to 10 35 cm −2 s −1 has been proposed to the Large Hadron Collider (LHC) ("SuperLHC") [2].…”

Abstract-We report on the measurement of interstrip parameters of p-type silicon strip sensors which we are developing in a large collaboration to be used in a future tracker for the LHC upgrade. We measure on test structures with about 1 cm long strips the interstrip resistance, interstrip capacitance (at 1 MHz) and punch-through protection both pre-rad and after irradiation with 70 MeV protons to a fluence of 1.5*10^13 p/cm^2, corresponding to about 1 MRad, from prototyping runs with Hamamatsu Photonics and Micron Semiconductors. We report the values for a variety of isolation scenarios of p-stops, pspray and a combination of both.

“…T HE proposed ten-fold luminosity upgrade of the Large Hadron Collider (LHC) [1] is motivating intense studies into upgrades of the trackers of the LHC detectors [2], which will require sensors capable of operating up to particle fluences of (pixel sensors), or (short strip detectors) [3]. The expected radial fluence distribution for ATLAS is shown in Fig.…”

“…The trapping time constant is also more favorable for electrons [11]. One needs to read out the signal at the main junction to be able to operate the sensor at partial depletion at high fluences, favoring n-on-n and n-on-p over p-on-n. Thinner p-on-n sensors would allow depletion even at high fluences, while there seems to be no reason for thinning p-type sensors except to reduce the amount of material [2].…”
