General EEEMCal Meeting Summary 2/8/21

TEAM ACTIVITIES PRESENTATIONS

IJCLAB-ORSAY (Carlos)

• Much expertise with calorimeters design and construction - one of the most recent projects: Neutral Particle Spectrometer; also active in EIC eRD1 calorimeter consortium crystal/glass project

• Specific expertise in scintillators include:

• simulations and component characterization (light yield, transmittance, etc.) - full test bench available
• EM irradiation facility (0.01-100 Gy/min)

• Interest in readout, e.g., development of backend and frontend electronics - experience from ATLAS ASIC development

• Expertise in design and engineering

• machine shop and prototype development and fabrication

• Possible contributions to EEEMCal R&D

• mechanical
• prototypes
• (micro)electronics development

• ACTIONS:

• EEEMCal specifications - collect on the Wiki
• Prepare list of R&D items

ARTIFICIAL INTELLIGENCE IN CALO DESIGN (Cristiano)

• Have built a model based on observation of detector response

• detector - multi-dimensional combinatorial problem
• AI can suggest next set of parameters to investigate at each point

• Expertise

• Bayesian optimization - including early stopping criteria to optimize computing resources
• Multi-Objective Functions - Pareto front, simultaneous optimization not dominated by either objective

• Examples of ongoing projects

• AerFi - mechanical reinforcement of aerogel tiles
• EEEMCal - crystal/glass material selection optimization

• optimization could be extended to include barrel
• tracking may also need to be considered

NEXT MEETING: MONDAY 22 FEBRUARY 2021 AT 9:00AM ET
