Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
We have fabricated silicon microstrip sensors in 150 mm p-type wafers and carried out irradiation of protons of 70 MeV up to 2x10^15 1-MeV neutron equivalent/cm^2. Full depletion votages along the fluence of the protons of 70 MeV have shown quite different development than those in 100 mm p-type wafers. The sensors are made of different isolation structures in the n-strip side....

Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
A large set of diodes processed by Micron on MCz and FZ n and p type materials was investigated up to equivalent fluences of 3e15 cm-2. Charge collection measurements were performed in addition to C-V. The charge collection efficiency was found to be better than expected from simulations and good agreement was found between full depletion voltages determined from charge collection and CV measurements.

Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
Radiation effects in standard FZ, DOFZ and MCZ Si diodes were evaluated with C/V, I/V and TCT measurements. FDV, I and trapping times were measured. Diodes were irradiated with protons and neutrons with fluences up to 3*10**14. Measurements after combined proton/neutron irradiation will be also shown.

Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
Silicon p-type detectors are being investigated for the development of radiation tolerant detectors for the luminosity upgrade of the CERN large hadron collider (super-LHC). Microstrip detectors have been fabricated by CNM-IMB with a n-side read-out on p-type high resistivity float zone substrates. They have been irradiated with neutrons at the TRIGA Mark II nuclear reactor in Ljubljana. The...

A setup for measurements with SCT128 chip was built in Ljubljana. First results of charge collection measurements with this setup will be presented. Measurements were made with miniature p-type microstrip sensors with n-side readout from Micron. Sensors were irradiated with neutrons up to 1 MeV equivalent fluence of 3e15 n/cm2.

We constructed in 2007 a beam telescope based on the CMS Tracker data acquisition prototype cards and the APV25 readout chips. The telescope has up to 8 silicon strip reference detectors and slots for couple of modules under test. The APV25 chip has a fully analog architecture, and it can be used for testing both p- and n-type detectors. The impact point precision of the reference tracks is 4...

Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
Several MCz diodes from the SMART production, of both n- and p- type, have been irradiated on the 24 GeV/c proton beam at CERN up to a fluence of 1.59 10^15 neq. In the framework of a common RD50 research program, electrical characterization and TCT studies have been performed as a function of the annealing time. All irradiated samples show a clear double junction effect. Both annealing and...

Radiation hardness properties of p-type substrate silicon micro-strip detectors: neutron and proton irradiations
The electrical isolation between the ATLAS pixels plays an important role for the electric fields in the pixel sensors and has an influence on the spatial resolution.
The simulation programs Dios and TeSCA are used to simulate n-in-n and n-in-p sensors with different geometries and isolation parameters before and after irradiation to study their effects on the operating conditions.

Double sided 3D n-type bulk detectors processed at CNM, Barcelona, have been characterised electrical and as charge collection devices at Glasgow. The detectors are readout via the p-type columns from the front of the device, while the n-type columns, which exit via the back of the device, are all shorted together. The IV and CV characteristics of the devise are presented before and after...

Calculations of 3D weighting field profiles have been performed 3 types of 3D detectors: single-type column, two-type columns, and double-sided two-type columns. It has been shown that for pitches less or equal to 50 um, the weighting field distributes throughout the detector, with half of the maximum strength in the middle of the cell (between the 4 electrodes/columns). The main limiting...

To cope with the increased luminosity of SLHC, the complete inner tracker of ATLAS must be upgraded. The talk aims to give an overview of current pixel detector activities with emphasis on R&D activities outside of 3D- and p-type-sensors. Apart from sensors, also FE developments and challenges for powering and cooling will be briefly described.
