HEP Instrumentation

Before 2020, the LHC will achieve its design energy (14 TeV) and luminosity (1034 cm-2 s-1). The increase in luminosity, which reflects the production rate of the events, is fundamental to extend the science reach of a collider. With the increase of luminosity, the available sample of events grows, and we will be able to investigate rare phenomena. After 2020, there will be a major collider upgrade to further increase the LHC integrated luminosity by one order of magnitude. As the accelerator is upgraded, the experiments must also undergo major overhaul to cope with the higher luminosity and to optimize the detectors’ performance.

SPRACE is developing part of electronic instrumentation for the phase 2 upgrade of the CMS  Level 1 trigger of the tracker detector. These developments are being done in direct collaboration with the Fermi National Accelerator Laboratory (Fermilab).

SPRACE is responsible for the development of an electronic system to monitor and control, in a reliable and scalable way, the power supply, cooling and the configuration of each component of the whole system, using the Advanced Telecommunication Computing Architecture (ATCA).

This monitoring and control functionality was implemented in the Pulsar 2b ATCA board (see http://www-ppd.fnal.gov/ATCA/) and it comprises two services:

  • Xilinx Virtual Cable (XVC) Service: allows the developers to access remotely the system via Internet.
  • Intelligent Platform Management Interface (IPMI) - monitors all sensors of the ATCA boards and allows, for instance, the auto-cooling control of the Pulsar 2b boards.

The video presents the step-by-step remote programming using XVC under the protection of IPMI and Shelf Manager.
