High precision and ultra-low mass tracking detectors based on the GEM technology.
The
CERN
group is currently optimizing the single mask GEM technology which allows building large
area detectors. The R&D program consists of the construction and evaluation of small size detector
prototypes and the performance comparison with detectors of alternative technologies Based on
prototypes and the performance comparison with detectors of alternative technologies. Based on
the results of these studies a full size prototype detector for
TOTEM
will be designed, constructed
and studied in a test beam. Electronics cross talk issues will be addressed in readout structure
design by detailed detector and signal simulations , the radiation tolerance and material budget will
be investigated.
The
LNF
group is working on an ultra-light, cylindrical and dead-zone free triple-GEM detector
(C-GEM) for
KLOE
made of five concentric layers A small size prototype has already been built
GEM) for
KLOE
made of five concentric layers. A small size prototype has already been built
successfully. The proposed detector is optimized for applications where large size combined with
low mass is essential. The project is technologically innovative and represents a significant step
forward with respect to the existing vertex tracking technology.
