R&D Project 2:
Integration of a low-mass silicon pixel detector system for particle tracking
Research Objective
A key towards the minimization of material budget in hybrid pixel systems is the reduction of external components and service chips that present-day front end for pixel detectors need for a correct operation. On chip cap-less regulators that avoid external filtering capacitors are employed in chips for mobile phones and other commercial System on Chips, but their use in particle detectors front-end, where the specifications on noise and radiation hardness are particularly demanding, remain to be assessed. Low-power transmitter coupled to ultra-light aluminum based cables allowing high speed electrical transmission over moderate distances (a few meters) would also be useful to avoid extra electro-optical components in zones where the material budget must be minimized. The design of such components and their integration on a realistic front-end demonstrator is therefore the natural complement to the low-power front-end cells with increased functionality developed in the ULISI project. Based on this chip, a full low-mass module prototype will be developed in ULISINT.
