PULSTAR Cryostat Arrives!

Posted on April 10, 2017 by rllongla

The cryostat for the PULSTAR systematics studies apparatus arrived last month! We’re currently commissioning the cryostat and performing first cool downs to 4.2K with liquid helium. We will then install a dilution refrigerator that will cool our 3 L volume of superfluid helium to below 0.3 K. The experiment will be situated inside the PULSTAR reactor and will use the new ultracold neutron source there to demonstrate the experiment techniques required for the success of the SNS nEDM experiment and will study many key systematic effects required to be understood, as our collaboration aims to discovery the never observed neutron electric dipole moment by reaching a sensitivity 2-orders-of-magnitude better than the current world wide limit.

A busy start to 2017

It’s been a busy start to the year with the publication of three papers!

Prof. Green’s group have a paper accepted to Physical Review Letters: Pauli Exclusion Principle violation, and electron decay from the low-energy spectrum of the MAJORANA DEMONSTRATOR
Prof. Gould and D. Stancil published a paper in the Results in Physics journal: Search for possible solar influences in Ra-226 decays
Kent Leung published a paper in Physical Review C: Spin flip loss in magnetic confinement of ultracold neutrons for neutron lifetime experiments

TUNL 50th Anniversary

Posted on August 19, 2016 by rllongla

After 50 years of history, the Triangle Universities Nuclear Laboratory (TUNL) continues to push the limits of nuclear physics. As a Department of Energy “Center of Excellence”, our lab is home to the world’s most intense proton accelerator dedicated to nuclear astrophysics, the world’s most luminous mono-energetic photon beam, and the only functioning Enge magnetic spectrograph in North America.
