Abstract :
A new Brute Force Low-Temperature Nuclear Orientation set-up has been installed. The aim of this new apparatus is to search for a tensor component in the weak interaction. The set-up consists mainly of a 3He–4He dilution refrigerator equipped with a 17 T superconducting magnet to orient nuclei and a Si PIN photodiode operating at a temperature of about 10 K for the detection of β -particles. The lowest temperature that has been achieved with this system until now is 4.9 mK in a magnetic field of 0.1 T and 8.6 mK in 14 T. The set-up is now fully operational and the first test measurements of the 60Co β -asymmetry have been performed.
