Abstract

New tracking detectors are necessary for beam diagnostics and event-by-event particle identification for the Super-FRS, a next generation reaction product separation being constructed at GSI/FAIR in Germany. Novel detectors and electronics are currently being developed to meet the stringent requirements of this forefront fragment separator due to high radiation levels, long term electronic stability and the required homogeneity of materials in the beam, while maintaining very high tracking efficiency. The present contribution focuses on the electronics for a new Gas Electron Multiplier (GEM)-based Time Projection Chamber (TPC) to provide the position information, which are needed to reconstruct the A/q of the fragment from protons to uranium ions. The most recent Front End Electronics (FEE) developed at GSI with a novel Amplifier With Adaptive Gain Settings (AWAGS) ASIC are being tested. This FEE has a low noise level (sub fC), a large dynamic range (up to ∼ 71 pC) with excellent timing properties. The AWAGS uses a switched capacitance technique instead of fixed feedback capacitors to provide the large dynamic range. Results from the ASIC characterisation studies and the outlook for a new, updated chip for the full read out chain of the GEM TPC are presented. [ABSTRACT FROM AUTHOR]
