“…Each of those planes, collection and induction, are oriented at 90°and count 32 paths with a pitch of 1.7 mm. Both planes are coupled to four cryogenic preamplifiers in total: one LARASIC4* [17] and three LARASIC7 each providing the amplification for 16 channels. The data acquisition (DAQ) was altered from that described in Ref.…”

First Operation of a Resistive Shell Liquid Argon Time Projection Chamber: A New Approach to Electric-Field Shaping

We present a new technology for the shaping of the electric field in Time Projection Chambers (TPCs) using a carbon-loaded polyimide foil. This technology allows for the minimisation of passive material near the active volume of the TPC and thus is capable to reduce background events originating from radioactive decays or scattering on the material itself. Furthermore, the high and continuous electric resistivity of the foil limits the power dissipation per unit area and minimizes the risks of damages in the case of an electric field breakdown. Replacing the conventional field cage with a resistive plastic film structure called "shell" decreases the number of components within the TPC and therefore reduces the potential points of failure when operating the detector. A prototype liquid argon (LAr) TPC with such a resistive shell and with a cathode made of the same material was successfully tested for long term operation with electric field values up to about 1.5 kV cm −1 . The experiment shows that it is feasible to successfully produce and shape the electric field in liquefied noble-gas detectors with this new technology.

“…The TPC contains 170 L (0.25 tonnes) of LAr. New wire planes have been installed on the TPC, as well as new cold front-end amplifiers from the MicroBooNE experiment [4,7]; the cryostat and TPC have also been modified to include scintillation light detectors. Data has been taken with three different wire pitches: 3 mm, 4 mm, and 5 mm.…”

This paper presents studies of pion scattering on liquid argon (LAr) with the LArIAT experiment. Pion scattering cross-sections on LAr are an important input to models of neutrino scattering used by current and future LAr neutrino experiments, such as MicroBooNE, SBND, and DUNE. LArIAT is a small LAr time projection chamber (LArTPC) in an instrumented testbeam at Fermilab. The precise calorimetry and tracking of LArTPC technology enable reconstruction of an interacting pion's energy as well as identification of secondary particles produced in the interaction. This makes possible measurement of the total pion-argon cross-section and exclusive interaction channels such as pion absorption, charge exchange, and scattering.

“…By using the latest cryogenic preamplifier technologies, one can partly compensate the signal attenuation and significantly improve the signal-to-noise ratio [56,[62][63][64]. The attenuation of the detector output signals by contaminant molecules grows exponentially with the drift time.…”

“…The LARASIC4, developed by BNL [56,[62][63][64], demonstrated outstanding performance and yielded high-quality data. While in April the read-out was realized with only 'warm' preamplifiers, half the number of channels were equipped with LARASIC4 cryogenic electronics for the run in June to study their performance in a real LArTPC.…”
