Low Material TPC construction — •David Markus for the MAGIX collaboration — Institute of Nuclear Physics, JGU Mainz
The MAinz Gas Injection Target EXperiment MAGIX, currently under construction in Mainz, together with the Mainz Energy-Recovering Superconducting Accelerator MESA, will perform electron scattering measurements on various gases, provided by a gas jet target. With an intended luminosity of 1035 cm−2 s−1 at 105 MeV, MAGIX is capable of servicing a wide variety of phyiscal objectives, including dark sector searches, investigations into few body systems and nuclear astrophysics.
The scattered particles will be measured with two identical high resolution magnetic spectrometers. In their focal plane a short drift GEM-based Time Projection Chamber is placed to serve as tracking detector. The active area of the TPC is 768x192x140mm. The setup of the experiment, from the internal gas jet target to the TPC, is designed to limit the interaction of scattered particles before their detection, such that the only seperator of TPC gas volume and interaction point is single kapton foil entry window. To assure that the desired precision can be achieved, a space saving calibration system using UV-LEDs has been designed. Plastic scintillators mounted after the capton foil exit window serve as a trigger veto system.
The low material TPC contruction and calibration system will be the focus of this talk.
