CMS Group

The CBG CMS Group – Leader Dr. Aurelijus Rinkevičius (Vilnius University).

Main objectives of the group:

  • Understand current engagement in CMS;
  • Define common areas for joint scientific research;
  • Get exposed and discuss future projects.

There is already a good experience in participation at CMS experiments as CMS users at computing and physics branches. There are also bright prospects in technical integration, detector systems and other related fields. Exchange of the experience between all three Baltic States will boost the output of participation in CMS.

The Baltics engagement is also expressed in personnel available in each country:

  • Estonia: 2 senior scientists, 3 postdocs, 1 PhD student participating from Tallinn in CMS. Tallinn is planning a Tier II computing network upgrade (links up to 100 Gbps).
  • Latvia: 2 senior scientists, 1 engineer, 2 PhD students.
  • Lithuania: 3 senior scientists in HEP, 3 in related material sciences (MS), 1 postdoc (MS), 1 PhD student.

EPIX and MTD upgrade talks presented high-level challenges in the detector upgrades, which seemed to be very difficult tasks according to Baltic Scientific Instruments Ltd. However, both detector upgrades have a large variety of tasks, where Baltic students could be fully qualified. A proper and future business-inspired detector project needs to be identified after further considerations.

The CBG CMS Group meetings:
1st CBG CMS Group Meeting

Date: 13-14 September 2018
Place: CERN
Chairpersons:
Aurelijus Rinkevicius (Vilnius University)
Toms Torims (Riga Technical University)
Topics:
Understand current engagement in CMS.
Define common areas.
Get exposed and discuss future projects.

The meeting had the main objective to define the current engagement of the Baltic States in the CMS experiment, identify mutual strength and weakens areas and come to first preliminary agreements on CMS projects. The participants of this meeting consisted of four institution and seven universities. As the first CBG CMS Group meeting, it was opened by reviewing the recent CMS accomplishments, realizing this group’s current global position and stating common goals.

First, each member state presented their current involvement status in CMS and the future plans, which was followed by a proposal for a distributed computing network in CMS experiments from Tommaso Boccali (Universita & INFN Pisa). This would increase the data computing capacity and also open new opportunities for the local IT industries and educational institutions.

Later, Lea Michaela Caminada (Paul Scherrer Institut) and Tommaso Tabarelli de Fatis (Universita & INFN, Milano-Bicocca) presented the latest technological upgrades at the CMS site (CMS Phase 2 upgrades). Extended Pixels (TEPX) and Precision Timing (MTD) presented high-level challenges in the detector upgrades, which seem to be very difficult tasks according to the “Baltic Scientific Instruments” Ltd. However, both detector upgrades have a large variety of tasks, where students could be fully qualified. A proper and future business-inspired detector project needs to be identified after further considerations. Industrial engagement in these upgrade projects was also discussed.

The conclusion of the meeting identified that further business engagement is needed to make a proper decision which project to join. CBG CMS Group agreed on the next topics to discuss, them being - physics research, computing and software, hardware and engineering.

2nd CBG CMS Group Meeting

Date: 8 April 2019
Place: Videoconference
Chairperson: Aurelijus Rinkevicius (Vilnius University)
Topics: physics, computing and software

The main goal for this meeting was to discuss the responsibility of CMS computing for the Baltics and identify joint efforts to maximize the effect of our presence. The participants of this meeting were six Baltic universities and the National Institute of Chemical Physics and Biophysics.

Each state presented their status and future plans followed by roundtable discussions, how to put the strengths together to achieve the declared goals of this work group. The attendees also agreed on the format and schedule of the following meetings.

3rd CBG CMS Group Meeting

Date: 12 April 2019
Place: Videoconference
Chairperson: Aurelijus Rinkevicius (Vilnius University)
Topics: computing, software, hardware and engineering

This meeting was a continuation of the meeting that took place on 8 April 2019. The meeting was attended by six Baltic universities and the National Institute of Chemical Physics and Biophysics.

This time the covered topics focused on the recent upgrade projects at the CMS experiment site like EuroHPC, TEPX, MTD and AOB. The present attendees discussed the opportunities for CBG at CMS in this regard.

4th CBG CMS Group Meeting

Date: 22 November 2019
Place: National Institute of Chemical Physics and Biophysics, Estonia
Chairperson: Mario Kadastik (National Institute of Chemical Physics and Biophysics)
Topic: CMS data computation (Tier II)

The overall objective of this meeting was to continue coordination of the CMS activities for CBG members. In particular:

  • computing, data acquisition and data processing engagement with CMS to exchange experience in the operating Tier II center and providing computing services and resources to CMS to evaluate technical feasibility of the joint Baltic Tier II computing grid within the Euro HPC initiative (like ex BalticGrid);
    More about Euro HPC at https://ec.europa.eu/digital-single-market/en/eurohpc-joint-undertaking
  • to discuss potential industrial engagement and OpenStack solution;
  • to foster contacts between relevant experts from CBG.

The participants were six universities and the National Institute of Chemical Physics and Biophysics.
