TILDA - fast experiment control and data acquisition in collinear laser spectroscopy experiments. — •Simon Kaufmann for the TRIGA-SPEC collaboration — Inst. für Kernphysik, TU Darmstadt — Inst. für Kernchemie, Johannes Gutenberg-Universität Mainz

The TRIGA-Laser Data Acqusition (TILDA) is a custom development for the collinear laser spectroscopy (CLS) experiment TRIGA-Laser. Situated at the research reactor TRIGA Mainz, the TRIGA-Laser experiment benefits from the possibility to create short-lived nuclides by neutron-induced fission of a heavy actinide target, e.g. ²⁴⁹Cf. The beam-line is equipped with a radio-frequency cooler and buncher emitting bunches with lengths in the order of 500 ns to 10 µs, which allows a drastical reduction of the background in CLS. In order to benefit from this bunched beam structure a time resolved data acquisition system is essential. The real time computing in TILDA is realized by field programmable gate arrays (FPGAs), which are synchronized via the backplane of a PXI-crate. This gives the user a great flexibility in adapting to different measurement schemes. This flexibility in hardware must therefore be given in equivalent way to the user in software. Due to that, high level programming languages were chosen (Labview and Python) and TILDA will provide the user with a solid framework around it. TILDAs main features, specifications, programming schematics and status will be presented.
