Energy-sensitive cryogenic detectors for high-mass biomolecule mass spectrometry.
Energy-sensitive calorimetric detectors that operate at low temperatures ("cryogenic detectors") have recently been applied for the first time as ion detectors in time-of-flight mass spectrometry. Compared to conventional, ionization-based detectors, which rely on secondary electron formation or the charge created in a semiconductor, cryogenic detectors measure low-energy solid state excitation...
متن کاملAdvanced Detectors for Mass Spectrometry
Mass spectrometry is an instrumental method capable of producing rapid analyses with high mass accuracy. When applied to genome research, it is an attractive alternative to gel electrophoresis. At present, routine DNA analysis by mass spectrometry is seriously constrained to small DNA fragments. Contrasted to other mass spectrometry facilities in which the development of ladder sequencing is em...
متن کاملHigh-energy resolution alpha spectrometry using cryogenic detectors.
Applications such as environment monitoring implying alpha emitters activity measurement associated with isotope identification, require high-energy resolution detectors. Conventional silicon detectors are inexpensive therefore widely used, although intrinsically limited in energy resolution. Thermal detection principle of cryogenic detectors introduces a breakthrough in alpha particle measurem...
متن کاملA Review on Mass Spectrometry Detectors
Mass spectrometry is an analytical technique for "weighing" molecules. Obviously, this is not done with a conventional scale or balance. Instead, mass spectrometry is based upon the principle of the motion of a charged particle that is called an ion, in an electric or magnetic field. The mass to charge ratio (m/z) of the ion affects particles motion. Since the charge of an electron is known, th...
متن کاملDark matter detection with cryogenic detectors
Direct detection of dark matter in the form of Weakly-Interacting Massive Particles (WIMPS) is an active field of research. Cryogenic detectors have been in the forefront of the field, due to their exquisite ability to reject backgrounds from interactions of normal matter. In this paper, I describe the current status and future prospects for such experiments. 1. The landscape of dark matter dir...
