Outcome of the CERN meetingsPreparing the upgrade R&D proposal

The meetings at CERN• We are encouraged to submit an upgrade R&D proposal ASAP.
– Internal review by an appointed committee: takes a few months.– Then a few weeks to allow other groups to join.– Focus on next year – producing a technical design report.
• Make FTKSim available to others.• Compare FTK and software tracking.• How are b-tag efficiencies correlated across levels?
– I think the last two bullets are not very important or at least derivative. More sophisticated algorithms can be carried out with FTK because more L2 time is available.
– What does matter is• Track efficiency• Impact-parameter resolution• Effect of the minimum PT of tracks• Effect of limiting the cone size for tracking
• Need current level-2 timing for 4-jet events.

Upgrade R&D Proposal• Introduction
– Importance of trigger flexibility, robustness, redundancy, operating margin
– Importance of 3rd-generation and the problem of its QCD background
– FTK: provides full tracking with high quality helix parameters @ L2 start
– Give a few physics examples (briefly).
– We propose to prepare a technical design report.
• Participating Institutions:– So far: Chicago, Illinois, Pisa
– Seek additional participation?• U.S.: Berkeley (Beate)
• Italy: Frascati, Rome, Pavia, …
• Topic & Goal, etc.:– FTK: where it fits in, data flow, how it works, dual-output HOLA in hand
– What this proposal covers: developing the TDR

TDR tasks (with dates & # of people)• Complete and document physics studies during R&D proposal
consideration.
• Complete FTK simulator
• Study performance vs. luminosity
• Data-path specification for 1034
• Determine size of AM
• Specs for each board: DF (strips & pixels), DO, AM, fitters
• Specify output format for ROBINs
• Physical layout: fibers, crates, cables
• Firmware needed
• Software needed: initialization, readout, monitoring
• Resources needed for design, construction & testing, commissioning, operating.
