    "abstract": "We present recent results on the operation of gas-avalanche detectors\ncomprising a cascade of gas electron multipliers (GEMs) and Micro-Hole and\nStrip Plates (MHSPs) multiplier operated in reversed-bias (R-MHSP) mode. The\noperation mechanism of the R-MHSP is explained and its potential contribution\nto ion-backflow (IBF) reduction is demonstrated. IBF values of 4E-3 were\nobtained in cascaded R-MHSP and GEM multipliers at gains of about 1E+4, though\nat the expense of reduced effective gain in the first R- MHSP multiplier in the\ncascade.",
