Hej! Here is a News Item on the Linnaeus University website containing a time-lapse video tracking the prototype construction progress (between January and June): https://lnu.se/en/meet-linnaeus-university/current/news/2018/1242-water-cisterns-will-examine-radiation-from-space/ And in Swedish: https://lnu.se/mot-linneuniversitetet/aktuellt/nyheter/2018/1-242-vattentankar-ska-undersoka-stralning-fran-rymden/ Enjoy!
Hej! Waiting for the final large ALTO scintillator detectors which we now ordered, in order to do some tests, we equipped the prototype site with smaller plastic and liquid scintillators recycled from another older experiment in France. Here below in… Read moreScintillators taking data together with the Cherenkov detectors
Hej! With a bit of delay, we are now updating the status of the ALTO prototype project on our Blog. On May the 25th our two water tanks were completely filled with water and the data taking started at 17:00… Read moreData taking with ALTO water Cherenkov tanks ongoing since May the 25th
Hej! This morning the city council employees helped us in setting up the water filling process. As usual, people are extremely professional here, and everything went perfectly fine. What we are doing now is a partial filling (of about 1m… Read moreFilling of Cherenkov tanks with water started this morning!
Hej! Today Jean-Pierre and Michael installed all the Data Acquisition System (DAQ) in our electronics box and the network has been connected by the IT at the University. So finally at about 18:00 CET we were able to see the… Read moreFirst air-Cherenkov coincidence event between ALTO tanks with the full DAQ chain!
Hej! This weekend we took advantage of the absolute calm of the campus to install the photomultipliers in the (empty) tanks. Everything went well, Michael and Jean-Pierre succeeded in positioning the devices and install all the cables for the signals,… Read morePhotomultipliers installed in the water tanks and work on electronics and network ongoing
Hej! Finally the large Cherenkov detectors arrived at the prototype site at Linnaeus University today. It took about one hour to put them in place. Everything went really well. Now we need to instrument them with the photomultipliers and the… Read moreWater tanks arrived at prototype site at Linnaeus University!
Hej! The large Cherenkov tanks are ready and they are now being filled with water for a first medium-term water resistance test at TBS Yard AB in Torsås. The expected delivery date for the large tanks on the prototype site… Read moreALTO Cherenkov tanks – water resistance test in progress
Hej! Finally the concrete structure is ready and soon we will be able to transport and put the big (empty) water tanks on it! In the meanwhile, the first ALTO water tank is getting ready for the final water resistance… Read moreALTO concrete structure ready – now waiting for Cherenkov tanks
Hej! 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. 🙂
