HADEDE

The goal of HADEDE project was to jointly develop a hand‐held spectrometer with an improved cooling solution based on the Stirling principle. To achieve this, it was crucial to minimize heat losses in the vacuum chamber of cryostat accommodating the germanium detector allowing the use of a low‐power Stirling cooler, a major power consumer in the device.
 

The collaboration between the partner has been intense to a) develop and validate the numerical model, b) develop the first prototype of the new HADEDE device, and c) ensure efficient feedback between the parties.  
 

As a result, the design of a handheld gamma spectrometer was improved significantly:  the spectrometer developed and manufactured in the HADEDE project is 5.6 kg lighter than a basic portable spectrometer, allowing for more ergonomic use and longer (especially field) operation times.

Publication of abstract and two scientific articles in topical technology journals was completed. 

The added value of cooperation comes mostly from knowledge sharing/spill‐over when two companies of different natures work on the same objectives,  i.e. developing a single device benefitting from expert knowledge from both sides. The combination of modern Computer-Aided Engineering (CAE)  approach and high‐quality manufacturing experiences for the design and optimization of a high‐technology spectrometer have realized in a smaller, lighter, and more energy-efficient product useful for environment protection in Estonia, Latvia and throughout the world.
