DESCRIPTION:Speakers: Magnus Mager (CERN)\n\nThis presentation will first 
 introduce ALICE and its main physics goals (study of quark-gluon plasma in
  heavy-ion collisions) together with the main observables and required det
 ection techniques that are particularly challenging in view of the long-te
 rm physics program called ALICE3. In order to face with this demanding pro
 gram\, the collaboration started a strong R&amp\;D on CMOS sensors. Over t
 he last 1-2 decades\, monolithic CMOS particle sensors have become the tec
 hnology of choice in applications where highest resolutions and lowest mat
 erial budgets are key: with pitches in the order of 20 μm\, they contain 
 sensing elements and readout circuitry in only a few 10 μm thickness. Tog
 ether with a very low power consumption this allows to build very light an
 d precise detectors\, which translates into excellent system-level perform
 ances. A large commercial interest in this technology - it is the same pro
 cess that is used for image sensors - drives a rapid development\, providi
 ng ever smaller feature sizes and higher integration densities\, very much
  to the benefit of their application as particle detectors. At the same ti
 me\, several specific optimizations have been developed to increase radiat
 ion hardness and speed\, as well as to lower power consumption. The latest
  incarnation\, the sensor for the new inner tracker\, &quot\;ITS3&quot\;\,
  of ALICE pushes the technology further in a number of aspects that will b
 e discussed in the Colloquium. &quot\;MOSAIX&quot\;\, the final prototype 
 of the ITS3 sensor\, has just been fabricated and marks a major milestone 
 in the field. Results from the R&amp\;D program will be presented\, showin
 g that it will allow to achieve the final vertexing and tracking performan
 ces of the whole inner tracker detector. Finally\, an outlook towards futu
 re applications and developments of monolithic CMOS sensors is given.\n\nh
