Projects

Detector, test and calibration electronics for X-ray science, most of it at European XFEL, the X-ray free-electron laser in the Hamburg area. These are short summaries: work that is not yet public stays out. The full record is in the CV.

01

Detector development for future XFEL detectors

2023 – present · European XFEL, Detectors Group

I lead the work package for electronics development in detector development projects at European XFEL. I take electronics for fast X-ray detectors from concept to a working unit: schematics, PCB layout, MCU firmware, prototyping and technical documentation. I also plan power supply and cabling for detector infrastructure at the scientific instruments.

Test systems for readout chips and sensors

2023 – present · European XFEL, Detectors Group

I led the design, assembly and commissioning of a test setup for single readout chips and new X-ray sensors, with power control, temperature regulation, data acquisition and integration into Karabo, the facility’s control software.

Calibration instrumentation for X-ray detectors

2023 – present · European XFEL, Detectors Group

I developed calibration hardware for JUNGFRAU and GOTTHARD-II, two X-ray detectors developed at the Paul Scherrer Institute and used at European XFEL: a backplane pulser for JUNGFRAU and a calibration device for GOTTHARD-II.

Model-based systems engineering

Since 2023 · European XFEL, Detectors Group

I introduced model-based systems engineering (MBSE) with SysML v2 and an AI-assisted engineering workflow to the group’s electronics projects, and I coach colleagues in AI-assisted engineering.

In parallel I am an Executive PhD candidate in Engineering Physics and Materials at Ca’ Foscari University of Venice, working on test instrumentation and AI-assisted model-based systems engineering for X-ray detectors.

Instrument electronics for HED and MID

2016 – 2023 · European XFEL, Scientific Instruments

As instrument engineer I looked after the electronics of two scientific instruments, High Energy Density (HED) and Materials Imaging and Dynamics (MID), from requirements to operation. I turned the scientists’ needs into technical specifications, ran trade-off analyses for critical components and coordinated system integration.

I designed and built custom devices: amplifiers, motion control, equipment-protection interlocks and power supplies.

Selected work

  • 2018HED controls infrastructure. Planned the controllers, vacuum pumps and other infrastructure for an instrument with more than 300 actuators (stepper and piezo motors, pneumatic actuators, hexapods) on Beckhoff PLCs; reviewed schematics before production; selected and commissioned actuators and sensors.
  • 2019HED interaction chamber IC1. Cabling concept for a large multi-purpose vacuum chamber: feedthrough pin-outs, vacuum-compatible Kapton twisted-pair cables with copper braid for in-vacuum motors, encoders and LED illumination, standards for suppliers, vacuum interlocks and a key system.
  • 2019MID X-ray Scattering and Imaging Setup (XSIS). Worked with the manufacturer on electrics and controls, led the factory and site acceptance tests and integrated the system step by step across a safety PLC, Beckhoff PLCs and Karabo.
  • 2021HED intensity and position monitor. A diagnostic that measures the intensity and position of each X-ray pulse from the backscatter of a thin foil. I mounted the six photodiodes in a clean room, designed their bias-tees for fast digitisers and wrote an adaptive attenuation routine in Python for Karabo.
  • 2022Karabo devices. Python drivers for piezo-motor controllers, a bridge that brings ZigBee sensors into Karabo through Home Assistant, and scripts for calibration, motion and vacuum control.

Control systems for high-current betatrons

2012 – 2016 · Tomsk Polytechnic University, Laboratory of High-Current Betatrons

Betatrons are compact electron accelerators; these were built for industrial non-destructive testing. I designed their control systems (schematics, PCB layout, microcontroller firmware) and power converters, and I commissioned, validated and troubleshot betatron installations.
