The protest of the workers of the Aria Foundation has arrived in Cagliari .

Today the 19 employees are in front of Villa Devoto to request President Solinas' signature on the program agreement between the Region and the National Institute of Nuclear Physics .

"Without that signature - say the unions - the contracts expiring on June 30 would expire and the workers would stay at home and the Aria project would be blocked".

The Aria project envisages the installation of a 350-metre cryogenic tower in a Seruci well for the distillation of argon, essential for research on dark matter .
