STREAM is a 4-year multi-site training network that targets the development of innovative radiation-hard, smart CMOS sensor technologies for scientific and industrial applications.
STREAM trains a new generation of creative, entrepreneurial and innovative early-stage researchers and widen their academic career and employment opportunities. The STREAM consortium is composed of 11 research organisations and 5 industrial partners; the network will provide training to 17 ESRs.
The project develops CMOS sensor technology to meet the demanding conditions posed by the CERN LHC detectorsâ€™ environment as well as in industrial applications such as radiation hard X-ray. STREAM structures the research and training in four scientific work-packages, which span the whole value-chain from research to application: CMOS Technologies Assessment, Smart Sensor Design and Layout, Validation and Qualification, Technology Integration, and Valorisation.
The current focus of the scientific work across technical work packages are:
- The optimization of designs for analog and digital functionality in different application areas,
- The preparation and test of demonstrator modules in order to evaluate the prototype sensor performances in view of their intended application,
- The study of commercial and scientific potential of radiation sensors in selected application areas of interest to STREAMâ€™s partners.
The STREAM Innovative Training Network started on 01 January 2016. Reaching now its second year, it has advanced both in the performance of CMOS sensors in high radiation areas. We have developed monolithic CMOS sensors in three different processes to optimize the performance in terms of charge collection, detection efficiency and response time.
Since the start of the STREAM project, all work packages have advanced significantly as planned in the evaluation of production and design processes, in the sensors design optimization, in the evaluation of the sensor performances and in the integration to demonstrator assemblies.
In parallel the project focused on the ESRs skills development and training.
The training of ESRs has been organised in the form of joint knowledge events and in the form of individual training to develop specific individual skills. A wide range of topics has been covered in three main axes are:
- Personal skills consolidation and improvement,
- Specific technical knowledge development on key topics for STREAM,
- Specific management and business skills
These subjects have been extensively developed in the Joint Training Course on Innovation Management and Technological Competence Leveraging at the Business School in Vienna (Wu-Wien, June 2017) and in the STREAM summer school held at CERN and Wu-Wien on 6-22 November 2017.
The ESRs have already contributed to an impressive amount of studies, concept design and system testing. Several works and publications have been produced and are ongoing in the STREAM framework. The publications were made in peer-reviewed physics and electronic journals as well as in conference proceedings. (e.g. publications in IEEE, JINST, Nucl Instruments And Methods., Journal of Applied Physics).
Personal and academic development of the ESRs
The STREAM ITN has an important impact on the training and individual experience of the ESRs. ESRs are truly working as a team, have elected their representative and have developed a platform to communicate among themselves via social media.
Most of the ESRs have familiarised with new cultures (in their home institute, during the training and during the secondment periods) and have already benefited from an intensive scientific and academic experience by having to adapt and expand their knowledge to new specific topics, and by having access to high level and intensive academic training at their university.
For their integration into the research community, the international research collaboration of the ATLAS experiment has become an essential part of their daily research environment. The ATLAS CMOS sensor development collaboration is a very active working group of internationally recognized researchers who give scientific guidance as well as feedback to the STREAM ESRs for their academic development and progress of their individual research projects.
Outreach and dissemination
The STREAM ESRs have participated to several outreach and dissemination events over the first two years, reaching the scientific and industrial community as well as high school students.
In 2017, the STREAM network put in place various actions to reach an international audience with the participation to special events, reductions of newsletters and a multi-channels publication available on open access IngentaConnect platform.
Scientific advancement in radiation hard microelectronics and particle detectors
The evaluation of initial prototypes produced by AMS, LFoundry and TowerJazz has shown that radiation hard CMOS sensors can indeed be manufactured in major CMOS processes. The results demonstrated their radiation hardness to unprecedented levels for monolithic active pixel CMOS sensors.
In view of future applications, common specifications have been established and are now the basis for future designs and demonstrators productions for particle tracking detectors for scientific application, for X-ray detectors for medical applications, for TEM microscopy and environmental sensors.
Technological innovations from the unique synergies between industrial partners in the fields of sensor research, microelectronics, their integration and many applications outside High Energy Particle are already achieved. The project contributes to facilitate and/or amplify knowledge exchanges between the industrial and academic partners, between different-sized industrial partners and other stakeholders in the field of particle detection.
Technology Valorisation and Real life projects
The ESRs have participated to state of the art technology developments and were trained in the field of management and knowledge transfer disciplines. STREAM, via the Work Package 6 Technology Valorisation and the dedicated trainings of the Work Package 7, introduces ESRs to the development of methods and tools that help institutions to benefit from the innovations generated and to entrepreneurial strategies. In particular, the ESRs have been actors together with Students of the Vienna Business School in real cases of technology and business developments for the beneficiaries CIS and ThermoFisher Scientific technology (Real-Life Knowledge and Technology Transfer project coordinated by the WU Wien).
