The ATLAS Level-1 Trigger requires several upgrades to maintain physics sensitivity as the LHC luminosity is raised. One of the most challenging is the electron trigger, with a major development planned for installation in 2018.
New on-detector electronics will be installed to digitise electromagnetic calorimetry signals, providing trigger access to shower profile information. The trigger...

As the LHC increases luminosity and energy, it will become increasingly difficult to select interesting physics events and remain within the readout bandwidth limitations. An upgrade to the CMS Calorimeter Trigger implementing more complex algorithms is proposed. It utilizes AMC cards with Xilinx FPGAs running in micro-TCA crate with card interconnections via crate backplanes and optical...

Many of the previous tracking triggers have been based on table lookups using content addressable memories. An alternative method is being developed that uses pairs of closely separated silicon sensors to incrementally find particle tracks. This system avoids a complicated memory lookup so it is fast enough to work as a level 1 trigger. We describe the readout and data processing architecture...
