Technical Training: ELEC-2005 - Electronics in High Energy Physics: Summer Term (May 2005)

ELEC-2005 is a new course series on modern electronics, given by CERN physicists and engineers within the framework of the 2005 Technical Training Programme, in an extended format of the successful ELEC-2002 course series.This comprehensive course series is designed for people who are not electronics specialists, for example physicists, engineers and technicians working at or visiting the laboratory, who use or will use electronics in their present or future activities, in particular in the context of the LHC accelerator and experiments.

ELEC-2005 is composed of four Terms. The last two Terms will run with the following schedule:

• Summer Term: System electronics for physics: Issues (May, 7 lectures) - now open for registration
  
• Autumn Term: Electronics applications in HEP experiments (November-December, 10 lectures)

Lectures within each Term will take place on Tuesdays and Thursdays, from 10h00 to 12h30. The course will be in English, with questions and answers also possible in French. Separate registration to each Term is required: attendance costs will be of 10.- CHF per lecture (Summer Term: 70.- CHF; Autumn Term: 100.- CHF).

Participation to any of the ELEC-2005 Terms is open: attendance to a Term is not a prerequisite to attend subsequent Terms. If you are interested in attending, please discuss with your supervisor and/or your DTO, and apply electronically via EDH. Participation to all sessions in a Term is strongly encouraged. Registered participants will be invited to each Term; attendance will be recorded in the personal training records.

The Summer Term - System electronics for physics: Issues - is now open for online registration, and will start on May 10th with the following programme:

Tuesday 10.5 - Radiation effects in electronics devices and circuits (Federico Faccio). Main effects of radiation on CMOS, bipolar and power devices: cumulative effects, such as Total Ionizing Dose; displacement damages; Single Event Effects (SEE). Sensitivity of modern devices to radiation damage, review of test methods. Methodology to estimate the rate of SEEs in the LHC environment from mono-energetic proton test data. How to achieve radiation hardness by design using deep submicron commercial technologies? Presentation of several design examples.

Thursday 12.5 - Modular electronics (Sophie Baron). Brief history of modular electronics. Mechanical and electrical standards, terminology and data transfer protocols. Installations: power and cooling, performance and limitations. Software and inter-crate connections. The future of modular electronics (VMEbus will be used to illustrate the various topics).

Tuesday 17.5 - Power converters for physics (1): High power converters (Frederick Bordry). Introduction to power conversion. Definition of sources and loads: current source and voltage source. Definition of switches definition: commutation, linear; hard and soft commutation. Converters families and topologies. Definition of power converter tolerances: accuracy, reproducibility, stability, resolution, ripple. Currents sources: current measurement, regulation, power, control. Power converters at the LHC. Power converters for physics (2): Low power converters (David Nisbet). DCDC converters: definition, applications, basic guidelines for use. Writing and reading specifications. Practical aspects of electromagnetic compatibility (EMC): definition, sources, effects, remedies. Current trends and system architectures. Applications and examples.
