Courses in Physics

Courses in Physics in the 28th Jyväskylä Summer School. The University of Jyväskylä reserves the right to make changes to the course programme.

PH1: Radiation interactions in electronic materials

Time: 6.-10.8.2018, 10 hours of lectures + 2 hours of lab work 
Participants: this course is aimed at PhD students and postdocs
Lecturer(s):  Dr. Arto Javanainen (University of Jyväskylä)
Coordinator(s):  Arto Javanainen / Prof. Ari Virtanen
Modes of study: Lectures and laboratory work
Credits: 2 ECTS
Evaluation:  Pass/fail

Contents: This course will introduce basic radiation matter interactions that are underlying the radiation effects in electronics. Emphasis will be on ion-matter interactions, but also the photon-matter interactions will be discussed. The above-mentioned subjects will be linked with the radiation hardness assurance (RHA) testing of electronics. Some basic methods involved in RHA will be introduced using the RADEF facility as the showcase. The course contains a laboratory work that will take place in the RADEF facility.

Learning outcomes: After this course, the student understands the basic concepts concerning radiation-matter interactions and can relate them with the radiation hardness assurance testing of electronic components. Also student will have knowledge on the principles of RHA testing.

Prerequisites: Basic knowledge on electronics and radiation matter interactions

PH2: Challenges and Radiation Performance of Advanced and Emerging CMOS Technologies

Time: 7.-9.8.2018, 6 hours lectures 
Participants: this course is aimed at PhD students and postdocs
Lecturer(s): Prof. Cor Claeys (KU Leuven, Belgium & Fellow IEEE, Fellow ECS)
Coordinator(s): Arto Javanainen / Prof. Ari Virtanen
Modes of study: Lectures and computer exercises (TBD)
Credits: 1 ECTS
Evaluation: Pass/fail

Contents: CMOS devices, driven by minimum device geometry, performance enhancement, cost issues and low power consumption, are achieved by using optimizing process modules, introducing new materials and implementing novel device concepts. FD technologies with ultra-thin body and buried oxide (UTBB SOI) have potential down to the 10 nm mode.  There exists strong competition between planar UTBB SOI and bulk FinFETs. Tunnel-FETs (TFETs), relying on band-to-band-tunneling and allowing steep subthreshold swings are enabling a lower power consumption. Further scaling leads to gate-all-around and nanowire devices. Optimized epitaxial growth resulted in the fabrication of Ge (p-channel), III-V (n-channel) or hybrid Ge/III-V devices on a Si substrate.
The radiation performance of several of these advanced and emerging technologies will be analyzed and discussed. Some of the available models to explain the experimental data will be reviewed.

Learning outcomes: After this course, the student knows the different technologies used in modern electronics and what are their differences in respect to performance and radiation sensitivity. Student will have an idea about the different mechanisms underlying the radiation response in the modern technologies and how they affect the designing of the components.

Prerequisites: Basic knowledge on electronics (transistor operation) and radiation matter interactions.

PH3: Introduction to parton distributions in perturbative QCD

Time: 13.-17.8.2018, 10 h lectures and 4 h exercises 
Participants: no upper limit
Lecturer(s): Dr. Hannu Paukkunen (University of Jyväskylä, Finland)
Coordinator(s):  Professor Tuomas Lappi and Professor Kari Eskola
Modes of study: attendance in lectures, solving exercise problems
Credits: 2 ECTS
Evaluation: Pass/fail

Contents: In this course, we will get acquainted with parton distribution functions (PDFs) which describe the quark and gluon content of the nucleons in high-energy collisions. Starting from the deeply inelastic scattering and QCD Feynman rules, we will derive the scale evolution equations for PDFs and consider their solution in the double asymptotic limit. Then, we will study the practical methods in data-driven analysis of PDFs. Out of the recent theory developments, we will review how to evaluate the photon content of the proton.

Learning outcomes: After the course, the student will have a vanilla understanding of the QCD dynamics of PDFs and basic knowledge of the methods used in their data-based extraction, thus possessing the necessary background to follow the research on the field.

Prerequisites: Quantum mechanics and elementary particle physics. Suitable for advanced Master’s students and upwards.

PH4: Light cone perturbation theory and small-x QCD

Time: 13.-17.8.2018, 10 h lectures and 4 h exercises 
Participants: no upper limit
Lecturer(s):  Dr. Guillaume Beuf (University of Jyväskylä)
Coordinator(s): Professor Tuomas Lappi and Professor Kari Eskola
Modes of study: attendance in lectures, solving exercise problems
Credits: 2 ECTS
Evaluation: Pass/fail

Contents: In this course, we will introduce light-front quantization as an alternative formulation for quantum field theories, in particular QCD, and show how to derive the light-front version of the Feynman rules for QCD. We will then present several applications of this formalism, in particular in the context of QCD at high energy (or equivalently low Bjorken x), such as the dipole factorization for deep inelastic scattering, or the hybrid factorization for forward particle production in proton-nucleus collisions.

Learning outcomes: From this course, the student will gain an elementary understanding of the light-front quantization of QCD, and will be able to perform tree-level calculations in light-front perturbation theory. He will also have a basic knowledge of low x QCD and gluon saturation, allowing him to explore further the literature in that field.

Prerequisites: Quantum mechanics and elementary particle physics. Suitable for advanced Master’s students and upwards.
