12-T magnet with dilution insert on WOMBAT during the experiment

Today we performed the first dilution-refrigerator experiment in a neutron beam at OPAL: using our WOMBAT high-intensity powder diffractometer.  

The sample was neodymium stannate, Nd₂Sn₂O₇, and a base refrigerator temperature of 40mK was achieved in zero magnetic field, and 50mK at 10T.  

Congratulations to our sample-environment team on this important achievement!
