Hi-pT ASIC
Coincidence of triplet and doublet data for low pT on candidates found in SLB ASICs for either wire or strip signals
Selection of 2 highest pT (>20 GeV/c) tracks from maximum 6 low pT (> 6 GeV/c) tracks
If no candidate is found, position (r or ) and displacement (r or ) data are simply bypassed.
Output data (10bits/track x 2) are serialised and formatted with so-called G-link compatible format.
No readout facility

Schedule
Hi-pT ASIC production version has been all delivered in 2002. Completed.
~100 (96) boards for Endcap wire~100 (96) boards for Endcap strip~50 (48) boards for ForwardThe boards are used only for trigger purpose.Installed in the Hi-pT crate which is put in the outer
rim of M1(triplet)We don’t yet, therefore, fix the detailed schedule of
board production.
