The M2 beam line at CERN is a unique hadron and muon facility. COMPASS has submitted a proposal requesting the extension of the COMPASS-II program in and beyond 2021. A Letter of Intent will be submitted by the end of 2017 suggesting a rich physics program to explore hadron structure using conventional meson beams, muon beams, and finally RF-separated hadron beams to enhance the fraction of...
The measurement of the proton radius is part of the proposal for the future COMPASS program. While continuing to use the DAQ and trigger system in the current way appears to be feasible, improving in particular the trigger is desirable to increase the number of recorded elastic events. I will present some ideas to achieve this, along with presenting the requirements to the COMPASS set-up for a...
Electronics Service of the Turin section of INFN (Electronics Laboratory) fulfills all the requests made by different physics research groups providing both design, systems realization and test capabilities of discrete electronics and microelectronics devices.
Design activities range from the very front-end electronics to the development of full read-out and data acquisition...
The presentation will describe the ASIC design activities at INFN Torino, with special focus on the developments for hybrid and monolithic pixel detectors, for timing measurements and for high speed data transmission circuit. ASICs currently used in various applications (ALICE ITS, COMPASS RICH, GBT common interface and medical interface) will be described, togheter with the recent...
The contribution presents development and recent status of the Data Acquisition Systems (DAQ) of the COMPASS experiment at CERN. It focuses especially on development and deployment of the new communication library DIALOG and DAQ Debugger for the error detection. The DIALOG library is a communication system both for distributed and mixed environments, it provides a network transparent...
The preliminary schedule of DAQ changes before the Run 2018 has been already discussed and accepted. There are prepared two major interventions. The current DAQ is limited to event size up to 512 KB. First intervention gets rid of such event size restriction and provides with more general DAQ. Second intervention takes into account the integration of cross-point switch. It considers all...
Having a graphical-only user interface to the DAQ has proven problematic in two matters: remote access and run control automation. This talk will address the current status of the command-line interface and describe how it solves these problems, including the “script mode“ feature introduced earlier this year. A short workshop session on how to write scripts against this interface will also...
In our contribution, we present several tools that simplify work with data taking shifts at COMPASSS experiment at CERN. At first, we introduce online shift reservation tool. Administrator (or year coordinator) can use the tool to define list of shift for given data taking period. Members of the experiment use the tool to sign in for shifts according to their preferences. The tool...
