In July 2013, Carleton University became the first North American research facility with a EUDET-class Monolithic Active Pixel Sensor (MAPS)-based Beam Telescope (EMBT) – a high resolution linear six panel detector that has the ability to determine the tracks of incident ionizing particles with great precision (up to 4µm accuracy per panel). The “telescope” design was created as part of the pan-European EUDET project, and was initially intended to provide a common detector and analysis software platform to evaluate and characterise new technologies being considered for use in the proposed International Linear Collider (ILC). However, the telescope was deliberately made general purpose, and several instances of the design have been built since the original was commissioned there, including multiple copies for use with test beams at both DESY and CERN. Carleton will be using the EMBT to assist in its ongoing world-class work in detector research and development; however, it will also be made available for use by scientists and engineers from other universities as well as industry. See About the EMBT for more information on its capabilities and architecture.

Since Carleton does not have a suitable particle accelerator, these facilities cannot replace a proper test beam campaign. The intention is for Carleton's facility to be used for integration, to validate the extensions required to the EUDAQ framework and EUTelescope reconstruction and analysis software for the device under test, and provide some initial real world data to faciliate the development and testing of custom analysis software. This strategy can be used to minimize potential problems, and maximize the amount of useful data that can be gathered, during precious beam-time windows. For a particle source, we are leveraging the pioneering work we have done with cosmic ray muons (see, for example, CRIPT). Although the muon flux is low, they make ideal particles for exploratory tracking studies as they have very high momenta and are not significantly deflected by most materials – thus providing nearly straight tracks through the telescope and any device or material under test.

While these facilities are made available on a competitive basis amongst groups wishing to use it, the advantage to testing at Carleton is beam time at an accelerator, which is always at a high premium, does not also need to be reserved. Please see Available Services for more information on reserving the EMBT and other services available through the physics department at Carleton University.
