• s = 14 TeV (7 times higher than Tevatron/Fermilab) search for new massive particles up to m ~ 5 TeV• Bunch crossing rate = 25 ns (~20 times higher than Tevatron)

• Ldesign = 1034 cm-2 s-1 (>102 higher than Tevatron/Fermilab)

22 interactions / BC 1400 particles / 25 ns• Rejection for Higgs search = 1013 (104 higher than Tevatron/Fermilab)

MABs

These light(~20kg.)carbon fibre structures are holding many active elements of the muon aligment system and guarantee their long term stable positions with respect to each other under working conditions at CMS.

36 MABs were produced by IMMG in Greece.

SummarySummary

•The GTPe has been designed and build in NCSR Demokritos•GTPe is a hardware emulator of the real GTP with its full capabilities apart LV1 connectivity•It has been tested in the lab and in real conditions at CERN.•It is an indispensable tool:

•for the development of TriDAS particularly concerning the partitioning•for the DAQ installation, when the real GTP will not be available.•For the DAQ upgrades during the operation of the experiment

•“The Global Trigger Processor Emulator for the CMS experiment” was accepted for publication in the IEEE Transactions on Nuclear Science
