MAJORANA

  • Last, but not least, the poly shield

    March 1, 2017

    For nearly seven years, the Majorana Demonstrator Project’s “shield team” has been building the six-layered shield that surrounds the experiment on the 4850 Level. In early March, they placed the last piece of polyethylene on the outermost layer of the shield. 

    “I’m proud of what the team has produced,” said Vince Guiseppe, assistant professor of physics at the University of South Carolina. “This was a complicated project. Every layer was added at the right time and fit perfectly.”

  • Majorana wins big with 'second string'

    In football, a coach has to be pretty desperate to put in the second string. The Majorana Demonstrator does things a little differently. Its second string—or cryostat—likely is the best. 

    “Our experiment design includes a prototype, followed by two cryostats,” said Adam Bradley, a postdoc with Lawrence Berkeley National Laboratory who works on the Majorana Demonstrator project. “With each cryostat, we’ve learned what not to do or what to do better or how to be more efficient.”
