Its Large Area Xenon Proportional Counters (LAXPC) have the largest collecting area of any X-ray instrument ever built, and it's currently the only one capable of studying X-ray fluctuations over millisecond time scales.
There are different ways for the measurement of radioactivity radiations such as Gas-Filled Detectors, Geiger Mueller counters, Proportional counters, Electronic dosimeters, Chemical Dosimeters, High- purity Germanium (HPGe) detectors, Cadmium Zinc Telluride (CZT) crystal detector, Organic and Inorganic Scintillators, Calorimetry, Cerenkov Detectors, slow- neutron detectors and Bubble Detectors.
The solid-state thermal neutron detector provides improvements in sensitivity, size, weight, power consumption, operator safety, transportability and cost compared to other available detectors such as gas proportional counters and scintillation counters," McGinnis said.
Two of the devices were position-sensitive proportional counters.
