Electrical characteristics of ATLAS07 Series I large detectors in Prague as step before irradiation was done.

42. Irradiation program in Prague - status.

Peter Kodys (Faculty of Mathematics and Physics), Dr Peter Kodys (Charles University)

04/06/2009, 09:05

Irradiation program in Prague is preparing on 2 possible way: on Cyclotron-based fast neutron facility at NPI Rez and in Experimental reactor at NRI, Rez. Basic conditions of this and plan for irradiation of ATLAS07 Series I large detectors will be presented .

6. Comparison of the CCE properties of microstrip detectors made with different substrates and irradiated with protons and neutrons at different temperature

Affolder Anthony (University of Liverpool)

The comparison of the charge collection properties of microstrip detectors made with FZ and MCz substrates are compared after irradiation with 26MeV and 24GeV/c protons and reactor neutrons. The lower energy proton irradiations took place at low temperature. The irradiations with the higher energy protons in the PS have been performed at room (>30oC) and cooled (about 0oC) T conditions. Their...

8. Anneling of Charge Collection in Strip sensors and the Depletion Voltage

Hartmut Sadrozinski (SCIPP, UC santa Cruz)

04/06/2009, 09:45

we have irradiated n-type and p-type magnetic Czochralski and Float Zone silicon detector to proton, pion and neutron fluences up to 1.3*1015 neq/cm2. The data are collected right after irradiation and after elevated temperature annealing at 60oC, corresponding to several years of annealing at room temperature. As a function of bias voltage V, the following electrical parameters were measured:...

40. Neutron irradiation for p-type sensors. Detector characterization with ALIBAVA system

Urmila Soldevila

This work describes the characterization of p-type microstrip detectors from two different manufacturers, Hamamatsu and CNM carried out at IFIC-Valencia. The sensors have been irradiated with neutrons at several fluences. In order to evaluate the macroscopic radiation damage, IV and charge collection measurements have been carried out by means of a radioactive source setup as well as by an...

12. The avalanche effect in operation of heavily irradiated silicon p-i-n detectors

Vladimir Eremin (Ioffe Physical Technical Institute)

04/06/2009, 10:55

The recent study of silicon detectors irradiated up to fluences beyond 10^15 neutron/cm^2 demonstrated an increase of the collected charge up to the value that is even higher than the charge initially generated by the detected particles. In the present investigation this effect is analyzed in terms of avalanche process in the abrupt p-n junctions. On the basis of double peak electric field...

7. Can we claim multiplication effects in irradiated silicon?

Gianluigi Casse (University of Liverpool)

04/06/2009, 11:15

New measurements to very high voltage are here shown that can give more support to the appearence of charge carrier multiplication effects in irradiated Micron silicon microstrip detectors

10. Measurements of lorentzangle in highly irradiated silicon-strip-detectors

Michael Schneider (University Karlsruhe)

04/06/2009, 11:35

The planned SLHC-Upgrade will result in a 10 times higher luminosity and therefore higher radiation-damage to the silicon-detectors in the tracker-subsystem of CMS. The magnetic field inside the tracker causes a shift of chargecarriers inside the detector-silicon resulting in a displacement of the measured position to the real position of the particles track. The angle the carriers are shifted...

22. Performance of irradiated MCz detectors in a test beam environment

Teppo Maeenpaeae (Helsinki Institute of Physics HIP)

04/06/2009, 11:55

The Silicon Beam Telescope (SiBT07) is a reference tracker used to characterize position sensitive detectors. I present selected testbeam results from irradiated MCz strip detector studies and discuss analysis methods associated with those results.

3. Commissioning the CMS pixel detector with cosmic ray data

Prof. Vincenzo Chiochia (Universitat Zurich)

04/06/2009, 12:15

The CMS Pixel detector, consisting of three barrel layers and two endcap disks at each barrel end, was installed in the CMS experiment in summer 2008. After a preliminary commissioning phase with pulse injections the detector participated in data taking with cosmic ray triggers and 3.8T field. We report on the first running experience with CMS and present preliminary results on detector...
