Introduction to the AIDA2020 project and the WP5 (Data acquisition system for beam tests)

What is AIDA-2020?

The AIDA-2020 project brings together the leading European research infrastructures in the field of detector development and testing and a number of institutes, universities and technological centers, thus assembling the necessary expertise for the ambitious programme of work.

WP5: Data acquisition system for beam tests

Visit the AIDA2020 WP5 webpage.

AIDA-2020 is divided into 15 Work Packages. A Work Package (WP) is a unit of work within the project. The WPs are theoretically independent but they were defined in order to foster synergies in AIDA-2020.

Objectives

• Specification of interfaces and provision of a control and timing system to allow multiple detectors to be linked together.
• Develop a central data acquisition software and run control to enable multiple detectors to be combined in one experiment.
• Develop monitoring systems to automatically check the data quality.
• Develop a system to monitor the environmental conditions, such as temperature, of several detectors.
• Define an event for online data where data is combined from detectors with very different signals and properties.

Tasks

Task 5.5: Event Model for Combined DAQ within the Linear Collider Community

EUDAQforLC

The use ofEUDAQ by the ILC community sttarted with CALICE calorimeters community which set out to develop a common DAQ with the support of EUDET in 2006-10, to fully exploit the benefits of having a common family of front-end readout chips. With the discontinuation of the support of ILC activities in the UK this effort dried out before completion and therefore a lost of coherence between calorimeters developments (scintillator, silicon and gaseous) . The issue of common DAQ and synchronization came up again during due to:

• demand to operate combined set-ups of electromagnetic (e.g. silicon based) and hadronic (e.g. scintillator based) calorimeters,

• the need to study hybrid prototypes (i.e. silicon + scintillator calorimeters in 2014)

CALICE community decided to use EUDAQ which is a modular and portable framework for DAQ, is well tested, maintained and successful.

We hope that this seamlessly integrates with the AIDA2020 efforts towards developing LC test beam standards for the entire LC community.

Towards ILC common test beams

It is proposed to run, during ILC ommon testbeams, in a synchronous mode with a central DAQ system: a central clock that delivers common start/stop signal for all systems that then read during the readout cycle. Proceeding in this way requires that all systems should agree on internal clock frequencies but it takes advantage of all independent standalone DAQ developments.

In this scheme, EUDAQ is proposed as central and high level DAQ.
