DRD Calo Collaboration Meeting at CERN
500/1-001 - Main Auditorium
CERN
The fifth DRD Calo Collaboration Meeting will take place at CERN between Tuesday 7th and Friday 10th April 2026.
The Year 2026 will be rich on scientific activities of the collaboration. We have proposed an intensive beam test programme and the meeting will be at the eve of the series of beam tests. In addition we expect to see results form 2024-25 beam tests.
It will be the first meeting that can take into account the recommendations of the European Strategy Group in view of the Update of the European Strategy of Particle Physics.
At the end of 2026 DRD Calo will ask for prolongation into the period 2027-29 and the meeting will be a first milestone event in view of this prolongation.
If you wish to contribute please contact the session and topic conveners:
- Work Package 1: Lucia Masetti (masetti@uni-mainz.de), Adrian Irles (adrian.irles@ific.uv.es)
- Work Package 2: Nicolas Morange (nicolas.morange@ijclab.in2p3.fr)
- Work Package 3: Hwidong Yoo (hwi.dong.yoo@cern.ch), Marco Lucchini (marco.toliman.lucchini@cern.ch)
- Work Package 4: Christophe de la Taille (taille@in2p3.fr)
- WG1 - Tools and software: Brieuc François (brieuc.francois@cern.ch), Lorenzo Pezzotti (lorenzo.pezzotti@cern.ch)
- WG2 - Photosensors: Maria Ruzzarin (m.ruzzarin@fbk.eu)
- WG3 - Testbeam: Gabriella Gaudio (gabriella.gaudio@pv.infn.it)
The DRD meeting will start on Tuesday 7th April in the afternoon with parallel sessions. The plenaries will start in the morning of the 8th of April and run until noon of the 10th. The afternoon of the 10th is available for supplementary events like software workshop, etc.
We will raise no conference fees this time. Coffee, Tea or whatever you prefer can be taken in the nearest CERN Cafeteria and we have arranged for a self-paid dinner on Thursday April 9th in Cafe de Mategnin. The price for the dinner will be 64 CHF (including the drinks option). Please indicate your participation and dietary requirements upon registration.
Let us thank Emily of the DRD Secretariat for the help with the organisation of the Collaboration Meeting.
