Spaceborne impact ionization mass spectrometers, such as the Cosmic Dust Analyzer on board
the past Cassini spacecraft or the SUrface Dust Analyzer being built for NASA's upcoming Europa Clipper
mission, are of crucial importance for the exploration of icy moons in the Solar System, such as Saturn's moon
Enceladus or Jupiter's moon Europa. For the interpretation of data produced by these instruments, analogue
experiments on Earth are essential. To date, thousands of laboratory mass spectra have been recorded with
an analogue experiment for impact ionization mass spectrometers. Simulation of mass spectra of ice grains
in space is achieved by a Laser Induced Liquid Beam Ion Desorption (LILBID) approach. The desorbed
cations or anions are analyzed in a time-of-flight mass spectrometer. The amount of unstructured raw data is
increasingly challenging to sort, process, interpret and compare with data from space. Thus far this has been
achieved manually for individual mass spectra because no database containing the recorded reference spectra
was available. Here we describe the development of a comprehensive, extendable database containing cation
and anion mass spectra from the laboratory LILBID facility. The database is based on a Relational Database
Management System with a web server interface and enables filtering of the laboratory data using a wide range
of parameters. The mass spectra can be compared not only with data from past and future space missions but
also mass spectral data generated by other, terrestrial, techniques. The validated and approved subset of the
database is available for general public (https://lilbid-db.planet.fu-berlin.de).
