A generic firmware core to drive the Front-End GBT-SCAs for the LHCb upgrade
نویسندگان
چکیده
The LHCb experiment has proposed an upgrade towards a full 40 MHz readout system in order to run between five and ten times its initial design luminosity. The entire Front-End electronics will be upgraded in order to cope with higher sub-detector occupancy, higher data rate and to work in a complete trigger-less fashion. In this paper, we describe a novel way to transmit slow control information to the Front-End electronics, by profiting from bidirectional optical connections and the GBT and GBT-SCA chipset capabilities. The implementation and preliminary validation tests are shown as well.

The GBT Project
The GigaBit Transceiver (GBT) architecture and transmission protocol has been proposed for data transmission in the physics experiments of the future upgrade of the LHC accelerator, the SLHC. Due to the high beam luminosity planned for the SLHC, the experiments will require high data rate links and electronic components capable of sustaining high radiation doses. The GBT ASICs address this issu...
متن کاملEMULATION AND CALIBRATION OF THE SALT READ-OUT CHIP FOR THE UPSTREAM TRACKER FOR MODERNISED LHCb DETECTOR∗
The LHCb is one of the four major experiments currently operating at CERN. The main reason for constructing the LHCb forward spectrometer was a precise measurement of the CP violation in heavy quarks section as well as search for a New Physics. To obtain interesting results, the LHCb is mainly focused on study of B meson decays. Unfortunately, due to the present data acquisition architecture, t...
متن کاملDYNAMICAL ANALYSIS AND DESIGN OF FRONT ENGINE ACCESSORY DRIVE SYSTEM
In this paper, Front Engine Accessory Drive (FEAD) system of automotive engine is modeled with ADAMS software. The model is validated using engine test data. It is then used to investigate the effect of design parameters on the system performance such as belt vibration and loads on the idlers. Three alternative layouts were developed in order to improve the performance of original EEAD system. ...
متن کاملThe LHCb Upgrade from 1 to 40 MHz readout
The LHCb experiment at the LHC will upgrade its detector to take data at luminosities of above 1033 cm−2s−1 from 2018 onwards. The fully upgraded detector will use a new front-end electronics to readout collision events at 40MHz. A new fully software based trigger will be implemented and will increase the trigger efficiencies, specially in the hadronic decay channels. The silicon vertex detecto...
متن کاملThe Effect of a 6-Week Core Stability Training Program on the Stroke Index and Front Crawl Record of Male Swimmers
Objective For optimal performance of swimmers, it is necessary to determine a level for the functional interaction of upper and lower limbs. This level, created by more than 20 pairs of muscles, is the core of the body. The aim of this study was to investigate the effects of six weeks of core stability exercise on the stroke index and front crawl record of male swimmers. Methods In this quasi-...
