Mass Separator

The beam produced by the gas catcher-ion guide combination is accelerated by an electrostatic potential of 40 kV. It is then transported to a mass separator.

The separator is a 55-degrees double focussing magnet with a bending radius of 1.5m. The mass resolution is around 1500 and provides sufficient seperation between to different masses. As a potential difference is applied between the gas catcher and the SPIG, the energy of the whole beam is affected and so is the separation; this effect is accounted for in the controls of the separator.

The beam is finally transported to the experimental area where three beam lines can be used: one in the center, one on the 'right' (+30 degrees) and one on the 'left' (-45 degrees). Only the right beam line is currently used with the tape station.

The LISOL separator was inaugurated on May 21^st, 1974 and shall celebrate its 35^th birthday next year. Watch for announcements!
