“…-Reduced material in the tracking volume; the material is the most severe limitation of the performance of the present tracker (see Fig.1, and also Ref. [2]), and it is dominated by electronics and services (notably in the region between barrel and end-cap): a tracker upgrade cannot leave out a substantial reduction of the material. -Ability to contribute information for the Level-1 trigger decision, in order to maintain the overall rate within 100 kHz 2 , without compromising the physics performance of CMS.…”

“…Hence, a possible option to investigate is to anticipate the use of tracking information in the Level-1 selection, along the lines of what is done today in the High-Level Trigger (HLT). 2 The limit at 100 kHz ensures compatibility with the electronics of subdetectors that will not be upgraded. A similar problem is present in the single electron trigger, where high pile-up reduces the rejection power of isolation cuts on the calorimeter clusters.…”

The planned upgrades of the LHC and its injector chain are expected to allow operation at luminosities around or above 5 • 10 34 cm −2 s −1 sometimes after 2020, to eventually reach an integrated luminosity of 3000 fb −1 at the end of that decade. In order to fully exploit such operating conditions and the delivered luminosity, CMS needs to upgrade its tracking detectors and substantially improve its trigger capabilities. To achieve such goals, R&D activities are ongoing to explore options and develop solutions that would allow including tracking information at Level-1. Some of the options considered are reviewed, discussing their potential advantages and disadvantages.

“…The quoted luminosity corresponds to more than 100 pileup events per bunch crossing if the operating frequency is 40 MHz. 1 For such scenario, CMS will eventually collect up to 3000 fb −1 , after several years of operation, and its tracking system will have to be improved in terms of radiation resistance, readout granularity and ability to contribute information to the Level-1 trigger. The whole tracker will have to be replaced at the beginning of the next decade: this upgrade will involve the outer strip tracker, as well as a further upgrade of the inner pixel detector.…”

The capability of performing quick recognition of particles with high transverse momentum (more than a few GeV/c) in the inner tracker is deemed essential to keep the CMS trigger rate at an acceptable level at a higher luminosity LHC (L > 10 34 cm −2 s −1). We present an architecture for a novel tracking module based on a combination of a pixelated sensor with a short strip sensor that would offer such capability. The critical aspects of the design such as the projected power consumption, the resulting material budget, and the data flow model are discussed and estimates are given. It is also shown that a manufacturable module of this type is well within the capabilities of currently available microelectronic and packaging-assembly technologies.

The planned upgrades of the LHC and its injector chain are expected to allow operation at luminosities around or above 5×10 34 cm −2 s −1 sometimes after 2020, to eventually reach an integrated luminosity of 3000 fb −1 at the end of that decade. In order to fully exploit such operating conditions and the delivered luminosity, CMS needs to upgrade its tracking detectors and substantially improve its trigger capabilities. To achieve such goals, R&D activities are ongoing to explore options and develop solutions that would allow including tracking information at Level-1. Some of the options considered are reviewed, discussing their potential advantages and disadvantages.
