  1. Portable Readout Electronicsfor MPGDs David Watts Nail Malakhov Developed for Readout of DPGP Front-end Electronics

  2. DPGP Electronics DPGP5 Hybrids 3DAQ MDAQ Diode protection

  3. DPGP Electronics Electronics Characterization • DPGP Hybrids + 3DAQ QuickUSB Readout • Dynamic range : up to 1pC • Lowest threshold: • 140fC all channels trigger • 15fC single channel trigger • Analogue Noise: • 0.8fC + 0.25fC/pF or 5100e +1500e/pF

  4. Compatible GEM Designs 10x10-130-SEALED TGEM 10x10-130 TGEM (unmountable) Cylindrical GEM

  5. DPGP Readout with TGEM 18% FWHM energy resolution at 5.9keV Serial mode readout : up to 50ksps Sparse readout : up to 1Msps Sparse-w-neighbors: up to 3Msps Purely digital : up to 8Msps Labview software for analysis and acquisition

  6. DPGP Readout with TGEM Fe55 source and a Banana plug Aluminum mask with 2mm holes

  7. DPGP Readout with TGEM Crosstalk and MIP Efficiency 26% of charge “lost” in neighboring channels Efficient for 6keV but NOT for MIPs  need trim-DAC threshold adjustment
