Description
The experiment IS739 studied fission reactions of radioactive beams in inverse kinematics at the ISOLDE Solenoidal Spectrometer (ISS). It required about 150 new channels of silicon detector readout. Placed after the REX/HIE-ISOLDE post-accelerator, ISS uses a free-running data acquisition system to cope with the low but intense duty cycle of the accelerator.
Readout of the new fission fragment Si CD and next-generation luminosity monitor detectors was realised through integration of a new free-running readout mode of Mesytec MDPP-32 modules with the existing system. Data-taking for the experiment took place this summer. The entire analysis chain was tested beforehand through simulations, generating data acquisition (DAQ) look-alike raw data files.
The layout and performance of the DAQ system and the simulation tools will be presented and discussed.
