| Outline of Final Research Achievements |
Gd concentration with AAS: In 2015 tests started using tantalum (Ta) and Wolfram (W) plates. By 2016 very good results were achieved with both Ta and W. Each material has its advantages and its drawbacks: Ta is very easy to work with but it is less resistant to high temperatures. W is more difficult to shape and fit in the AAS' cuvettes but it is much more resistant to high temperatures. In 2017 we were planning to publish a paper but Hitachi stopped the production of its cuvettes. We are now adjusting our design to the new ones before publishing resulting in a temporary delay.
Using Gd magnetic properties: We did several device designs but we didn't reach the required sensitivity. We may have done a mistake in evaluating the feasibility of this technique with such a cheap cost. As demonstrated in our proposal the principle is correct and feasible but given our budget constraints to build this device, it may not be possible. Nevertheless, we are still trying and did not give up yet.
