A benign, low Z electron capture agent for negative ion TPCs
C. J. Martoff, M. P. Dion, M. Hosack +2
We have identified nitromethane (CHNO) as an effective electron capture agent for negative ion TPCs (NITPCs). We present drift velocity and longitudinal diffusion measureme…

On the Mechanism of Townsend Avalanche for Negative Molecular Ions
M. P. Dion, C. J. Martoff, M. Hosack
Time projection chambers drifting negative ions (NITPC) instead of electrons have several advantages. A NITPC can operate at very high reduced drift fields without diffusion runawa…
