There are several persons who (mainly) work with electronics & electricity:

  • Attila Hidvégi (development, design and construction of digital electronics, FPGA and firmware programming, software development)
  • Holger Motzkau (development, design and construction of analog and digital electronics, front panels & enclosures)
  • Per Halldén (electrical installations)
  • Mikael Björkhage (instrumentation, system installation, electronics service)

Equipment & capabilities

Design & software

The electronics group can draft schematics and design a wide range of printed circuit boards (PCBs) ranging from simple single-sided boards for e.g. sample holders to advanced multi-layer boards for FPGAs, high-speed/frequency or mixed signal applications. We have experience with several manufacturers of PCBs, as well as front panels, enclosures, and racks enabling us to design complete systems.

Besides several open source and freeware tools we have licenses for tools for hardware design, software development and simulation, like:

  • Altium Designer
  • Mentor Graphics (PCB development / signal integrity simulation)
  • Xilinx (Vivado Design Suite -  SDK / ISE / EDK)
  • LabVIEW
  • Solid Edge
  • Comsol Multiphysics

Production & assembly

We can assemble most things from simple to high-voltage, high-frequency, vacuum-suitable cables, from plated-through-hole boards to surface-mounted designs down to 0402 (metric component size 0.4 mm x 0.2 mm) and simple BGAs (Ball Grid Array connection arrangement), and from simple boxes to full racks and subracks. For larger quantities or advanced assemblies and front panels we have experience with external companies. In the workshop we have among other tools:

  • Microscopes
  • Soldering stations
  • Reflow oven 30x30 cm
  • Pre-heater
  • Hot air
  • Variety of crimp tools


Some tools are located in the workshop/Technical Division, others are available elsewhere at the department.

  • Spectrum analyzers (5kHz-1GHz/1Hz BW, 1Hz-3GHz-1Hz)
  • EMC (electromagnetic compatibility): Near field probes, current clamp, LISN (Line Impedance Stabilization Network), shielded room
  • Oscilloscopes (4x200 MHz, 2x100 MHz battery powered, faster available at the department)
  • Logic analyzer
  • Function generators (3 MHz, 30 MHz, 200 MHz)
  • Multimeters
  • Laboratory power supplies

Component stock

Stock with a large number of standard components.


The Technical Division can help with electrical and other infrastucture installations for labs and experiments. For more information, please see the page about other services offered by the division.


Some of the projects the Technical Division works on:


  • High-voltage amplifiers, 500V - 20kV
  • Low noise amplifiers, transimpedance/Faraday cup amplifiers
  • Power supplies
  • Bias Tees
  • HF amplifiers
  • Breakout boxes
  • Sample holders


  • High-speed data acquisition systems:
    • High-speed 4-channel ADC board with USB 3.0 - (SuperSpeed) connection.
    • High-resolution multichannel time-tagging and coincidence detector unit.
  • TileCal daughter board for Atlas upgrade: 14 layer PCB, 2x Xilinx Ultrascale+ FPGA, 4x 10GB SFP+
  • Raspberry Pi/touchscreen controlled systems
