An Isobaric Analog State is defined as certain nuclear states belonging to neighboring nuclear isobars and possessing identical structure except for the transformation of one or more neutrons into the same number of protons.It should be noted that in this case the term "isobaric" refers to ions or particles of the same mass.

Preliminary Projects

First Beamline

The first beamline we constructed was on the +15 port of the switching magnet. The basic structure was intact; we removed extra beamstands and an ancient Sargent-Welch turbo pump station to clear out space. We added an Ion Pump to the upstream section, ie, the portion before the Magnetic Quadrupole. With the S-W turbo station gone, we had to rotate a tee and add a 90 degree bending Dependex to ISO MF adapter so that we could connect an Alcatel 5150 turbopump. A glass vacuum chamber is connected to the beamline with a double o-ringseal.
