GRETA Dedication: Celebrating a Decade of GRETINA Science

GRETA Project Director Paul Fallon and Berkeley Lab's Deputy Director for Research Carol Burns stand in between GRETA's detector hemispheres to conduct the "ribbon cutting" ceremony while several key people involved in the inception, delivery, and future use of GRETA join the celebration. On the left side of the photo (from left to right) are Sergio Zimmermann (former project manager for GRETA from Berkeley Lab’s Engineering Division, now retired), Thomas Glasmacher (FRIB Laboratory Director), Marie-Agnes Deleplanque (a former Berkeley Lab senior staff scientist and Nuclear Structure Group lead, now retired), and Natalie Roe, Berkeley Lab's Associate Director for the Physical Sciences. On the right side (from left to right) are I-Yang Lee (a former senior staff scientist in the Nuclear Structure Group, now retired), GRETA Deputy Project Director Heather Crawford, and Nuclear Science Division Director Reiner Kruecken.

Direct neutrino-mass measurement based on 259 days of KATRIN data

The KATRIN beamline. Tritium gas is continuously injected into the source, where it decays, producing β-electrons. (Inset) The source volume, filled with a plasma of low-energy electrons and tritiated ions. The tritium gas is pumped out, purified, and recirculated, whereas the electrons are guided magnetically through the transport section into the spectrometer. Only electrons with sufficient energy to overcome the electrostatic potential in the analyzing plane are counted at the detector. The analyzing plane is shifted toward the detector for background reduction.
