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.
