Micromegas with GEM preamplification for enhanced energy threshold in low-background gaseous time projection chambers [version 2; peer review: 2 approved]

Micromegas with GEM preamplification for enhanced energy threshold in low-background gaseous time projection chambers [version 2; peer review: 2 approved]

Background We develop the concept of a Micromegas readout plane with an additional GEM preamplification stage placed a few millimetres above it to increase the maximum effective gain of the combined readout. Methods We implement it and test it in realistic conditions for its application to low-backg...
