History - SHRIMP I
The original SHRIMP (now called SHRIMP I) was designed and built from around 1974 to 1981. Dr Steve Clement, an ANU student who designed and built a mass spectrometer for his PhD) was recruited by Professor William Compston to produce a design for SHRIMP that enabled high mass resolution while maintaining sensitivity. The SHRIMP design was based on a published work by Professor H. Matsuda of Osaka University for a double-focussing mass spectrometer that included a quadrupole lens to minimize second order aberrations. Most of the components were manufactured in the RSES Mechanical and Electronics Workshops. SHRIMP I featured full computer control of data acquisition.
The SHRIMP I stage control was replaced by a computer-controlled version in 2006 to allow automated running from preselected points. This also saw the end of the highly reliable Apple Macintosh II computer with the incorporation of a PC running the LabVIEW software.
SHRIMP I was decommissioned in late 2010 after nearly 30 years of service. Elements of the ion optical system can be viewed in the SHRIMP laboratory.
