Learn About the Vacuum Equipment Leading Neutrino Discoveries

Posted on: June 4, 2021

The Applied Vacuum Division (AVD) of Anderson Dahlen, which designs and manufactures custom chambers and precision components for Extreme High Vacuum (XHV) requirements, is providing critical products to research groups at the forefront of the recent surge in neutrino research.

While neutrinos are one of the most abundant particles in the universe, they are very difficult to detect because they have little interaction with matter. But, as you will learn, this hasn’t stopped the cutting-edge neutrino research, which has been continuing to pick up and deliver incredible findings.

Here’s an overview:

  • Key Insight from the Deep – A telescope is being used to search for neutrinos below the ice of Russia’s Lake Baikal – the world’s deepest lake and a perfect site for observation. Neutrinos, uncharged particles that move incredibly fast, have almost no mass and can pass through matter, including people and the earth itself. In rare cases, neutrinos provide a faintly detectable glow when they hit an atomic nucleus in water. Placed on the lake’s bed, the telescope gathers information that aids researchers’ understanding of supernovas and black holes. The telescope can monitor less than half the required volume but it has recorded evidence of neutrinos multiple times. Watch the video for more insight … and some pretty incredible scenery. 
  • From Waconia to Los Angeles – Anderson Dahlen is proud to have shipped its 316L SS chamber, frame and special hardware from its Waconia, Minn. facility to UCLA, where the chamber will be utilized to support the HUNTER (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) project. Loaded from a source of radioactive 131 Cs through a subsidiary loading Magneto-Optical Trap (MOT), The HUNTER is built around a high occupancy, low-temperature MOT. The HUNTER project is a collaboration between Temple University, UCLA, The University of Houston, and Princeton University to conduct a laboratory-scale experimental search for a new sterile type of neutrino.
  • Pressure Vessel at the Center of Experiments – Anderson Dahlen manufactured a dual-certified Ultra-High Vacuum (UHV)/American Society of Mechanical Engineers (ASME) pressure vessel, which offers gas containment in addition to the hosting and support for a Barium ion source and various detector prototypes. The vessel has been serving a crucial function as part of research being conducted at the University of Texas at Arlington by Dr. David R. Nygren who, in 1976, developed the first Time-Projection Chamber (TPC) at Lawrence Berkeley National Laboratory. Dr. Nygren has established a new unit to conduct research at the forefront of particle detector technologies and train the next generation of detector experts.
