  "description": "<p>The NeuLAND (New Large-Area Neutron Detector) plastic scintillator based time of flight detector for 0.2-1.6 GeV<br>\nneutrons is currently under construction at the Facility for Antiproton and Ion Research (FAIR), Darmstadt, Germany.<br>\nIn its final configuration, NeuLAND will consist of 3,000 2.7 m long plastic scintillator bars that are read out on each<br>\nend by fast timing photomultipliers.<br>\nHere, data from a comprehensive study of an alternative light readout scheme using silicon photomultipliers (SiPM)<br>\nare reported.&nbsp; For this purpose, a typical NeuLAND bar was instrumented on each end with a prototype of the same<br>\ngeometry as a 1&rdquo; photomultiplier tube, including four 6&times;6 mm2 SiPMs, amplifiers, high voltage supply, and micro-<br>\ncontroller.<br>\nTests were carried out using the 35 MeV electron beam from the ELBE superconducting linac with its ps-level time jitter in two different modes of operation, namely parasitic mode with one electron per bunch and single-usermode with 1-60 electrons per bunch, using Acqiris fast digitizers. In addition, offline tests using cosmic rays and the NeuLAND data acquisition scheme were carried out.<br>\nTypical time resolutions of &sigma;&le;120 ps were found for &ge; 95% efficiency, improving on previous work at ELBE and exceeding the NeuLAND timing goal of &sigma; &lt;150 ps. Over a range of 10-300 MeV deposited energy in the NeuLAND bar,&nbsp; the&nbsp; gain&nbsp; was&nbsp; found&nbsp; to&nbsp; deviate&nbsp; by &le; 10%&nbsp; (&le;20%)&nbsp; from&nbsp; linearity&nbsp; for&nbsp; 35&mu;m&nbsp; (75&mu;m)&nbsp; SiPM&nbsp; pitch,&nbsp; respectively, satisfactory for calorimetric use of the full NeuLAND detector.&nbsp; The dark rate of the prototype studied was found to<br>\nbe 70-200 s-1, comparable with the unavoidable cosmic-ray induced background.</p>\n\n<p>The dataset contains the with the Acqiris Digitzier recorded waveforms and analysis scripts for interpretation of the data. Also GEANT4 simulations of the light propagation in a NeuLAND bar and the electron beam propagation are included.</p>",
