Micromegas with GEM preamplification for enhanced energy threshold in low-background gaseous time projection chambers
J. Castel, S. Cebrián, T. Dafni +13
Background: we develop the concept of a Micromegas (MICRO-MEsh GAseous Structure) readout plane with an additional GEM (Gas Electron Multiplier) preamplification stage placed a few…
