The room of measuring the infrared temperature radiometer detector is a matrix comprised of a network micro bolometer, without separate cooling system, allowing dynamic data recording system.
The new scintillating bolometer has performed excellently, proving its viability as a detector in experiments to look for dark matter, and also as a gamma spectrometer (a device that measures this type of radiation) to monitor background radiation in these experiments", said Abancens.
Then they could relate the steps by means of different tenses (I "used" a bolometer, which my assistant "had prepared"), by means of conjunctions and adverbs conveying temporal meanings ("After" we prepared the mixture, we "then" opened the slit), and by means of the order of clauses in a sentence (We prepared the light source, which we allowed to fall on the slit).

Researchers didn't have to wait anywhere near that long to detect the tell-tale alpha decays because the huge number of bismuth atoms in even a single bite-size bolometer crystal guarantees that some atoms will break down in a matter of days, if they break down at all, de Marcillac says.
