DESCRIPTION:Speakers: CALVO\, Daniela (INFN-Torino (IT))\nThe PANDA experi
 ment will make use of antiproton cooled beams of unprecedented quality\, t
 hat will become available at the Facility for Antiproton and Ion Research 
 (FAIR) in Darmstadt\, featuring up to 2•10^11 antiprotons and momentum b
 etween 1.5 – 15 GeV/c.\nTo handle forward particle distribution due to t
 he Lorentz boost\, the apparatus is arranged in an asymmetric layout aroun
 d the interaction point between antiprotons and pellet or gas jet target. 
 \nThis peculiarity requires a tracking detector with a forward design and 
 in particular an innermost Micro Vertex Detector (MVD) based on silicon de
 vices with an innovative design in an unusual geometry. The material budge
 t of this silicon tracker has to be minimized in view of particle momenta 
 ranging from few hundreds of MeV/c up to several GeV/c. Besides high inter
 action rate asks for fast data readout being PANDA without low-level trigg
 er selection and particle identification is planned over the full range of
  energies.\nTo cope with these requirements MVD includes innermost layers 
 made of thinned epitaxial silicon hybrid pixel detectors and outermost com
 posed of double side silicon micro strips.\nIn particular the mechanics in
 tegration of the pixel detector is a challenge due to the compact volume o
 f the MVD asking for specific solutions as carbon foam both to increase th
 e heat dissipation towards the cooling pipes and acting as mechanics suppo
 rts.\nTo cope with high data rate new non-triggered readout chips develope
 d in 130 nm CMOS technology feature high speed readout and charge measurem
 ent with Time over Threshold\, and to deal with the limited material budge
 t request new aluminium strips are developed for data transmission and spe
 cific busses design are under study. \nResults concerning the developments
  of prototypes to solve critical items will be presented.\n\nhttp://indico
