Ready to pour the concrete slab!


We are surprised on how quick the construction of the concrete structure is proceeding. Good to know! Now the workers are ready to pour the final concrete slab in four hexagonal shapes. :)


Prototype construction proceeding at an amazing speed!


We are proceeding at an amazing speed! The concrete feet supporting the water tanks are also ready! Next week the company will produce the "tables" on which we will then place the big tanks. In the picture, Michael is profiting from a momentary absence of the workers to stand in the middle of the structure. :)


Ground preparation & underground concrete base both finished

Despite the huge load of snow, the ground preparation has proceeded smoothly and is now finished.

The underground concrete base is ready, next step is the construction of the concrete pillars and the water tank concrete bases.

In parallel, the construction of the water tanks is ongoing at TBS Yard AB in Torsås, see picture below.

First carbon fibre panel for the ALTO water tanks is infused at TBS Yard AB


Here are some updates on the ALTO prototype construction in Växjö :)

The first panel in carbon fibre which will be used for the construction of the ALTO water tanks is infused and ready at TBS Yard in Torsås. In total 6 of these panels will be produced for the two water tanks. Each panel is going to be cut in pieces to form the hexagonal shape of our tank.

Here is a picture from Lars Tedehammar, CEO of TBS Yard AB.

July 2017 - ICRC 2017 presentations done!


We presented the ALTO project at the ICRC2017 in Busan (South Korea) in a talk and in a poster and now we are relaxing a bit before the construction of the prototype.

Our two contributions were the first two made in a big international cosmic-ray conference. Next scheduled presentations at conferences will be at Astronomdagarna 2017 in Kiruna and at the Texas Symposium in Cape Town. You can download the material of our presentations from the page called "Presentations & Articles" on our website.

We are still waiting for the building permit, so the construction of the prototype will not not start before August... stay tuned!
