First ALTO paper
Our first peer-reviewed paper “Signal extraction in atmospheric shower arrays designed for 200 GeV – 50 TeV gamma-ray astronomy” is published in the Journal of Instrumentation (JINST). The arxiv version is available here. The JINST published Open Access version can be found here. Our method can be useful also for other ground-based gamma-ray observatories using…
Big Data 2019 and Open Science tutorial
Hej! Big Data 2019 at Linnéuniversitetet is approaching. Invited speakers, Fast-Forward sessions and a cool tutorial in Open Science! Come and mingle with the Data Intensive Sciences and Applications (DISA) people! All the information about the event can be found at this page. We will present 4 posters related to ALTO/COMET activities: Data analysis for…
A new type of water tank!
Hej! Our prototyping activities are going on 🙂 After a successful operation of the carbon fibre tanks, we are now completing the prototype setup with two brand-new water tanks made of steel. Here Michael, Mohan and Mark are in front of their creation. They have tightened quite many bolts (300!) for the first new tank….
Big Data Hackathon
Hej! We will provide ALTO simulations and real data for the Big Data Hackathon organized in the framework of DISA at Linnaeus University. This event supports open source and open science. Join us!
All Phase-I ALTO detectors taking data!
Hej! Finally, all our Phase-I ALTO detectors are taking data. The second muon detector still needs to be filled with additional scintillator liquid, and we will do this soon. The Phase-I of the ALTO prototype consists in the operation of two full ALTO units (two water tanks and two muon detectors). We also have other…
Restyling and new webpages
We have almost completed the migration of our website on this new platform. In addition, now the astroparticle/gamma-ray group has new webpages with all our other research activities in gamma-ray astronomy: https://astrogamma.se/
ALTO Event Display available in live streaming!
Hej! We now have the possibility to send a live stream of the cosmic ray events detected by the ALTO prototype at Linnaeus University. Check it out on our website and have fun!
First muon carpet taking data with all other detectors!
Hej! After additional testing needed to understand our new detector element, we finally got the first ALTO muon detector taking data properly with all the other detectors included in the prototype. Temperatures in Växjö have already reached -12 degrees and therefore we are operating the prototype elements under these extreme conditions. The temperature in the…
First muon detector “carpet” installed!
Hej! Today we received the first muon detector that we will fill with a liquid called “scintillator” next week. Next week we will also install the photomultiplier which will record the photons emitted by the passage of particles in the scintillator liquid. Here are some pictures from the delivery and installation, and a video from…
