## Overview of the SiLC R&D Activities

The R&D Collaboration SiLC (Silicon tracking for Linear Colliders) is based on generic R&D aiming to develop the next generation of large Silicon tracking systems for the Linear collider experiments; it serves all three ILC detector concepts. There is a strong involvement in ILD, a natural collaboration with SiD and recent 4th concept interest to use Silicon tracking technology as well. Here is a very brief summary of the latest results on sensors, Front End Electronics, Mechanics and Integration issues, test bench and test beam results and where to go from there.

## Large Silicon Tracking Systems for ILC: Role, Design and Main issues

The roles, the designs, the main issues and the current status of the R&D on large Silicon Tracking Systems for the ILC are discussed in this paper. The R&D work presented here is performed within the SiLC (Silicon tracking for the Linear Collider) R&D Collaboration.

## A new 130nm F.E readout chip for microstrip detectors

In the context of the Silicon tracking for a Linear Collider (SiLC) R&D collaboration, a highly compact mixed-signal chip has been designed in 130nm CMOS technology intended to read Silicon strip detectors for the experiments at the future International Linear Collider. The chip includes eighty eight channels of a full analog signal processing chain and analog to digital conversion with the corresponding digital controls and readout channels. The chip is 5x10mm2 where the analog implementation represents 4/5 of the total Silicon area.

## Silicon Data Acquisition and Front-End Electronics

A highly integrated Front-End readout and Data Acquisition scheme for Silicon trackers is presented. In this context, a 16-channel readout chip for Silicon strips detector has been designed in 180nm CMOS technology, having in view a highly multiplexed and sparsified readout global strategy. First results are presented.

## Extraction of the x-dependence of the non-perturbative QCD b-quark fragmentation distribution component

Using recent measurements of the b-quark fragmentation distribution obtained in $e^+e^- \to b \bar{b}$ events registered at the Z pole, the non-perturbative QCD component of the distribution has been extracted independently of any hadronic physics modelling. This distribution depends only on the way the perturbative QCD component has been defined. When the perturbative QCD component is taken from a parton shower Monte-Carlo, the non-perturbative QCD component is rather similar with those obtained from the Lund or Bowler models. When the perturbative QCD component is the result of an analytic NLL computation, the non-perturbative QCD component has to be extended in a non-physical region and thus cannot be described by any hadronic modelling. In the two examples used to characterize these two situations, which are studied at present, it ...

## A 16-channel Silicon Strips Readout Chip in 180nm CMOS technology

A highly integrated readout scheme for Silicon trackers making use of Deep Sub-Micron CMOS electronics (DSM) and analog sampling techniques is presented. In the context of the International Linear Collider (ILC) tracking detectors developments, a 16-channel readout chip for Silicon strips detector has been designed in 180nm CMOS technology, each channel comprising a low noise amplifier, a pulse shaper, a sample and hold and a comparator operated at low power. Test results are presented.
