Prof. Dr. Eng. Christelle Reynard-Carette (1974) graduated in Thermal Sciences at Aix Marseille University in 1998 and obtained her PhD on heat/mass transfer in microgravity (boiling, thermocapillary convection, parabolic flights) at the same university in 2001. She is professor at Aix Marseille University (laboratory IM2NP UMR7334, DETECT depart- ment, team Microsensors-Instrumentation). She is deputy director for research of ISFIN institute (Institute of Fusion Sciences and Instrumentation in Nuclear Environments). She conducts research on the design, development, miniaturization and characterization of sen- sors for the on-line measurement of key quantities within nuclear reactors (absorbed dose rate/nuclear heating rate, calorimetry, irradiation campaigns). She led/leads several joint research programs with the CEA (IRESNE, Jules Horowitz Reactor) within the framework of the AMU-CEA-CNRS joint laboratory LIMMEX (Instrumentation and Measurement in EX- treme Environments) created in 2010 and for which she is responsible for AMU and CNRS. She collaborates with various partners and international nuclear centers. As an example, she is in charge of two A*Midex projects involving the MIT’s Nuclear Reactor Laboratory (CALOR-I project for research area, MOBIL-APP project for education area). She is also in- volved in the ANIMMA conference and the Franco Moroccan school EFMMIN since their creation (member of the scientific and steering committees, organization chair workshops). She is also responsible of two master’s tracks in instrumentation, measurement and metrol- ogy (in particular a new international track dedicated to Instrumentation and Measurement Science for Major Nuclear Research Facilities which started in 2022).

The nuclear heating rate, corresponding to an intense absorbed dose rate induced by the various interactions between radiation and matter and leading to an increase in temperature in the matter, represents a key nuclear quantity for research reactors and their as- sociated irradiation experiments in terms of thermal, thermal-hydraulic and mechanical design and data interpretation. The nuclear heating rate is measured on-line by means of specific calorimetric sensors called calorimeters. There are two types of calorimeters: the single cell calorimeter and the differential calorimeter. The short course will present:

• their design, materials, instrumentation and assembly,
• their thermal principle,
• their calibration under laboratory  conditions without nuclear radiation,
• their measurement methods under  real conditions (irradiation  campaign),
• their main characteristics (sensitivity, measurement range, response  time…),
• their advantages and drawbacks,
• the associated challenges.

The short course will be illustrated by the comprehensive approach conducted at Aix-Marseille University to innovate in calorimetry by coupling experimental work with simulations from laboratory conditions to real conditions and illustrated by focusing on the CALORRE differ- ential calorimeter used in the MITR reactor in October 2024.

The course is an introductory lecture about how medical imaging is handled in medical en- vironments. This will be focused to help to provide what are the most common techniques for understanding and minipulating several groups of medical images, including xray, CT MRI and US.

She started working in the construction of detectors for different particle physics experiments at PSI and CERN and later on she specialized in detec- tors for medical imaging. She has always worked in the development of novel technologies and techniques at the frontiers of the state of the art and within international projects and collaborations. She has collaborated with numerous research groups, mainly from Switzer- land, Italy, Germany, Slovenia, USA and Canada. Her current interests focus principally on the development of Compton cameras for hadron therapy treatment monitoring and for vi- sualization and dosimetry of the distribution of radionuclides in the patient’s body in Tar- geted Radionuclide Therapy. Overall, she has participated in more than 25 funded research projects (mostly Spanish, Italian and European) and been the P.I. of more than 10, some of them in collaboration with hospitals and protontherapy centres. She has also led several in- novation and valorization projects and R&D contracts with companies. Concernig training of young researchers, she is a lecturer in the Masters of Medical Physics and of Advanced physics of the University of Valencia since 2009 and 2014 respectively. She has supervised eight PhD theses and over 30 research works from Bachelor, Master and Erasmus+ students. She is the president of the medical physics group of the Spanish Royal Physics Society (RSEF) since 2019. She is founder and main organizer of the RSEF/IFIMED medical physics confer- ence (four editions since 2016) and co-organizer of the RSEF Biennial Symposium and CPAN days.

This lecture will revise in a descriptive way the origins of medical imaging, the evolution and the latest advances and current research of the detectors employed in diagnostic (SPECT, PET and CT) and therapy (radiotherapy, particle therapy). It will cover the following topics:

• Gamma cameras, SPECT and Compton cameras.
• PET: from block detectors to time-of-flight PET.
• CT scanner generations.
• Therapy with photons and protons.

The NEXT experiment (Neutrino Experiment with a Xenon TPC) is designed for the study of neutrinoless double-beta decay, a hypothetical process that, if detected, could provide crucial insights into the nature of the neutrino and the violation of lepton number con- servation. The NEXT experiment employs a high pressure time projection chamber (TPC) technology filled with xenon gas to achieve high-precision detection of rare events. As part of this project, the student will conduct a detailed analysis of real data containing Krypton (Kr) events. These data will be obtained using the NEXT-DEMO++ detector, a demonstra- tion version of the main experiment operating at the Instituto de Física Corpuscular (IFIC). The purpose of this analysis is to characterize the detected events and measure their en- ergy resolution. To carry out this study, a Jupyter Notebook will be used, an interactive programming tool that will allow for efficient visualization, processing, and analysis of the data.

This DEMO allows to simply and quickly measure the discharge current of a capacitance of an RC circuit as a function of time, and determine from it the time constant of the circuit. The RC-DEMO is assembled using sets of capacitances and resistors (to vary the time constant values) connected in series to a project board. The capacitance is charged using a 9 or 12V battery and the circuit is connected to one of the 16 analog inputs of an Arduino Uno, which is programmed to record charge or current with a sampling rate of 16 MHz. The students will use a combination of resistors and capacitors to set up an RC circuit using the RC-DEMO elements, and will measure its discharge current as a function of time to determine the time constant of the circuit.

Multi-anode PMTs are position-sensitive photomultiplier tubes (PS-PMTs), that are usually coupled to scintillation crystals and read out using the Anger  logic with a resistance network. In this session, an 8x8 PS-PMT (H8500) coupled to a monolithic BGO scintillation crystal will be deployed to obtain the energy spectrum of diferent gamma-ray sources, as well as the sensitivity to  spatial displacements of collimated  sources. Thanks to the resistance network, only 4 channels out of the 64  anodes are extracted and digitized with  an oscilloscope. The gamma-ray  interaction position can then be  reconstructed using a centerof- gravity  equation.

This is an introductory course on particle detection and triggering in High Energy Physics. Strategies for event selection in real time in modern particle physics experiments will be presented. Basic concepts such as data size, rate, bandwidth, dead time, busy, efficiency, etc. will be presented. The course will be structured as follows:

• Trigger and Data Acquisition (DAQ) system concepts
• From signal to physics
• Event building
• Online data processing

Most accelerators deployed worldwide use radiofrequency technology (from 3 Hz until 3 GHz) to accelerate particles. To apply this technology, it is necessary to design complex data acquisition and processing systems able to deal with high frequency signals. In this session, we will analyze the behavior of several electronic components that compose the most critical system elements. To do so, we will deploy a vector network analyzer (VNA) that gives information regarding the amplitude and phase of the transmitted and reflected signals within these elements. In addition, we will setup an RF circuit to decrease the fre- quency of an input signal and use a spectrum analyzer to understand it’s behavior. Tasks: calibrate and measure the scattering parameters of RF components with a VNA; setup and analyze a mixing circuit to decrease the frequency of an input signal.

This lab session focuses on using the MACACO III Compton Camera to study gamma rays emitted by a Na-22 point source. The session begins with the setup of the system, concen- trating on the two detector planes utilized for the measurements. A spectrum is measured in singles and another in coincidences, with comparisons and discussions on their differ- ences. The coincidence spectrum is then calibrated to account for the detector’s energy response. Finally, a reconstruction algorithm is applied to generate an image of the Na-22 source’s position.

Participants will get familiar with the sophisticated pixel detector Timepix through the session of practical hands-on exercises performed with SESTRA educational kit. Participants will learn how to build an experimental set-up, how to configure measurement  parameters, how to run acquisition and  how to evaluate measured data.  The basic types of radiation produced  by several emitters, including natural  radiation background, will be studied  and distinguished according to  recorded tracks via the pixel detector.  Further, the properties of each kind of  radiation will be examined.

Participants will learn more about sophisticated Timepix detectors via demonstration of three advanced experiments: Application of Timepix in a delayed coincidence measure- ment exploiting time-of-arrival and spectroscopy information in order to identify (alpha- gamma or gamma-gamma) coincidence events observing a radiation source. Detection of neutrons via adapted pixel device using converter materials suitable for fast or thermal neutrons. Analysis of Timepix data recorded on the ground level, on-board of the airplane, on the satellite orbit focusing on identification of space radiation and its specifics.
