Exploring LTSpice: Solutions and Studies by Sasha Milov on March 6, 2007

On March 6, 2007, Sasha Milov delved into LTSpice to explore critical questions about Floating Mesh behavior and voltage effects between two modules. This session addressed stability concerns with prototypes and real detectors, and investigated issues related to short circuits in GEMs. Sasha analyzed current dependency related to resistor-capacitance coupling and showcased measurements of 60 Megohm and 40 Megohm resistors under high voltage on GEM configurations. These insights contribute valuable understanding to our ongoing studies in this area.

  3. Floating Mesh • MT only happen between the two modules sitting at high enough voltage?  our killer question from Friday studies (!) • MT are confined to one arm, and have no other patterns • Prototype was more stable, then real detector • More short problems in top GEMs • Two modules with mesh-gem shorts Sasha Milov playing LTSpice...
