Technical Division

The Technical Division offers support for the implementation and operation of the big equipment (HPLS, LBTS, the VEGA system) and for the integration and operation of the experimental set-ups. The activity of the division has also a technical development component in supporting the research and development activity on the experimental side. The Technical Division of ELI-NP comprises 5 sub-divisions: Technical Design Office, Mechanical and Vacuum Workshop, Electronics Workshop, Target Laboratory, Dosimetry Laboratory.

Technical Design Office - responsible for the design and simulation of mecanics or electronics.

The Design Office is in charge of mechanical, electrical and electronic design, development and simulation of parts needed in the process of implementation, operation or development of the HPLS, LBTS, VEGA System and the complex experimental systems around them.
The engineers are collaborating with research groups in order to place orders and decide on the manufacturing process of the designed parts or systems.

Mechanical and Vacuum Workshop - technical support for manufacturing of mechanical parts and systems and the vacuum across facility

The workshop is responsible for the manufacturing of the mechanical parts and systems needed for the implementation and operation processes.
It is working in close contact with the design office and offering technical support for the experimental areas.

Electronics Workshop - technical support and development of electronic circuits and automation devices

This workshop is responsible for troubleshooting and repairs on the complex electronic devices operating in the facility, but also for the development of electronics or automation systems that are needed for further development of the experimental set-ups or the improvement of the big machines.
The Electronics laboratory, from Electronic Workshop, offers several services associated to this specific field of activities such as maintenance of equipment, repairs, technical support for preparing and performing experiments. The laboratory is equipped with machines that can be used for measurements of electrical parameters in physics and applied electronics at ELI-NP, so that the design and development of prototypes (in small quantities), electronics modules, adaptors and simple automation devices can be executed properly. These activities serve for research, in general, as well as for supporting ELI-NP’s experiments and utilities. The measurements made in this laboratory are essential for investigating potential malfunctions of devices used in experimental set-ups as well as for the checkup of homemade systems/devices.

For the activities described above, the following devices are used in the laboratory:

Oscilloscopes (500MHz, 2.5 Gs/s)
Signal and Functions generator
Power supplies
Various probes
RLC bridges
Small electronic and electrical components such as resistors, potentiometers, capacitors, transistors, diodes, LEDs, integrated circuits, relays, voltage regulators, buzzers, etc.
Various cables for power or transmission of data (e.g. coaxial cables)
Target Laboratory - research and development for target material for research with laser and gamma

The most complex laboratory in the division, the target laboratory has a strong research component related to the development of special materials used as targets in experiments.

The manufacturing process starts after establishing the procedure in correlation with the research process. The target laboratory, currently encompassing 270 m2 area of cleanroom-environment (ISO 6 and ISO 7), is dedicated to the development, fabrication, characterization and micro-assembly of targets for experiments with high power lasers and gamma beams. Accommodating a wide range of state-of-the-art equipment and a specialized team of materials scientists and engineers, the target laboratory is set up to address the demands for targets, provide support throughout the entire process: from proposal evaluation of the target to technical feasibility to target delivery; and to perform R&D activities in order to continuously develop and upgrade novel target designs. In-house production of targets (within ELI-NP’s Target Laboratory) results in benefits such as avoiding the damage of fragile targets (which usually occurs during transportation), meeting specific target requirements in terms of chemical stability and purity, ongoing optimization of target key-parameters, custom-made possibilities and last-moment modifications and adjustments of the targets, through characterization of targets just before the shot, but also, in the long run, and additionally reduced manufacturing costs due to in-house development of technologies and methodologies.

Among the cutting-edge equipment and capabilities available in the Target Laboratory are:

two ultra-high vacuum deposition systems (RF/DC sputtering deposition and e-beam evaporation, for thick/thin/ultra-thin (ultra)pure metallic/nitrides/oxides films fabrication), equipped with an Ar-ion milling unit (for cleaning the wafers prior to deposition) and Nanogen unit (for nanoparticles deposition)
optical lithography tools (mask aligner, spin coater, hot plates)
reactive ion etching tool and electron beam lithography system (for structuring/patterning the targets), tubular furnace, calcination furnace and vacuum drying oven (for surface conditioning and sample processing) along with a specialized chemistry room
scanning electron microscope (SEM) with microanalysis by energy dispersive X-ray spectroscopy (EDS) and electron backscatter diffraction (EBDS)
X-ray diffractometer (XRD)
atomic force microscope (AFM)
optical profilometer (confocal, interferometry)
several optical microscopes
universal machines for precision mechanics and micromechanics processing (lathe and milling), accompanied by a set of related accessories required for processing operations (orientation fixtures and parts, devices, tool holders etc.)
Dosimetry Laboratory - services for dosimetry of the personnel and the operation and maintenance of the radiation monitoring system for the facility

The dosimetry laboratory supports the radiation safety group in monitoring the personnel exposure to ionizing radiation, and operates and maintains the radiation monitoring systems.
