Description
The CMS tracker at sLHC is required to provide prompt PT information to the trigger to maintain the 100kHz LHC level 1 rate. Simulations show that a promising technique to achieve this is by correlating hits in two closely spaced strixel layers (~ 1mm spacing, ~ 100 um x 2.5 mm strixels), the so-called stacked tracking approach. While direct vertical correlations between strixels is a possible method for constructing a module (the 3-D approach), simulated occupancies indicate that this can also be achieved by transferring cluster information to the edges of modules (the 2-D approach), where cluster information from both layers can be brought together to find correlations. We believe this will lead to a module design that could be simpler and cheaper to prototype and construct. We present the current status of the proposed 2-D PT module design, in terms of the logic architectures necessary to implement the required functionality, and associated power consumption estimates.
