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 He-3-He-4 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 beta-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 Co-60 beta-asymmetry have been performed. (c) 2005 Elsevier B.V. All rights reserved.
