CMB-S4: Forecasting Constraints on Primordial Gravitational Waves
/ CMB-S4 Collaboration
CMB-S4---the next-generation ground-based cosmic microwave background (CMB) experiment---is set to significantly advance the sensitivity of CMB measurements and enhance our understanding of the origin and evolution of the Universe, from the highest energies at the dawn of time through the growth of structure to the present day.

(PSI, Villigen) ; Vallazza, E. (INFN, Trieste)
Several detector types have been designed and assembled in order to monitor charged particle beams in a wide range of intensities: silicon microstrip detectors for high precision tracking (spatial resolution better than 5 μm), a scintillating fiber tracker with multianode photomultiplier readout for coarse but fast monitoring, a microstrip silicon detector readout by a counting ASIC to monitor very high intensity beams. These detectors and their readout electronics have been characterized at the BTF (Beam Test Facility) of the INFN National Laboratories of Frascati and used on the H8 line at the CERN SPS as tracking media for the data taking of the H8RD22 collaboration.

Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energies at LEP
/ ALEPH Collaboration
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3~fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from $130~GeV$ to $209~GeV$ [...]

Precision electroweak measurements on the $Z$ resonance
/ ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]

We discuss the results obtained from the R&D; studies, done within the CMS experiment at LHC related to the behaviour of silicon microstrip prototype detectors when they are operated at high bias voltages before and after heavy irradiation, simulating up to 10 years of LHC running conditions. We have found detectors from several manufacturesrs that are able to work at V_bias > 500 Volts before and after the irradiation procedure, maintaining an acceptable performance with S/N > 14, efficiency close to 100% and few ghost hits..

The paper describes the Silicon Tracking System of the Compact Muon Solenoid ( CMS) and reviews the most recent results of the R&D; activity on radiation resistant microstrip silicon detectors. The Silicon Tracker of CMS consists of 5 layers of microstrip detectors in the barrel and 10 disks on either side of the end-cap region. [...]

Investigation of design parameters for radiation hard silicon microstrip detectors
/ Braibant, S ; Demaria, N ; Feld, L ; Frey, A ; Fürtjes, A ; Glessing, W D ; Hammarström, R ; Honma, A ; Mannelli, M ; Mariotti, C et al.
In the context of the development of radiation hard silicon microstrip detectors for the CMS Tracker, we have investigated the dependence of interstrip and backplane capacitance as well as depletion and breakdown voltage on the design parameters and substrate characteristics of the devices. Measurements have been made for strip pitches between 60 and 240 mu m and various strip implants and metal widths, using multi-geometry devices, fabricated on wafers of either <111> or <100> crystal orientation, of resistivities between 1 and 6 k Omega cm and of thicknesses between 300 and 410 mu m.

CMS silicon tracker developments
/ Civinini, C ; Albergo, S ; Angarano, M M (INFN Perugia and Univ., Bari, Italy) ; Azzi, P ; Babucci, E ; Bacchetta, N ; Bader, A ; Bagliesi, G ; Basti, A ; Biggeri, U et al.
The CMS Silicon tracker consists of 70 m/sup 2/ of microstrip sensors which design will be finalized at the end of 1999 on the basis of systematic studies of device characteristics as function of the most important parameters. A fundamental constraint comes from the fact that the detector has to be operated in a very hostile radiation environment with full efficiency. [...]
