When the source of particles has a time dependent variation in intensity, the conventional dead time correction may not apply. A new dead time correction that applies in this case is presented.David LaundySPIE Conference on Hard X-Ray, Gamma-Ray, and Neutron Detector Physics...
If a neutron detector is placed near a very intense source, it can become saturated because of detector dead time. On the contrary, if it is placed far away from the source, it will lose counting statistics. For this reason, there must exist an optimal position for placing the detector. ...
PURPOSE:To make it possible to adjust dead time of an X-ray detector system only by one variable resistor and to know the dead time simply as the length of a TTL digital pulse by an oscilloscope or the like, by changing continuously the width of an output pulse waveform outputted from ...
Further the related problem of pile-up is often confused with the deadtime phenomenon. Much work, is needed to devise a generalized and practical solution to these related problems. Many methods have been developed to measure and compensate for the detector deadtime count loss, and many ...
The method described in this paper is based on the fact that the distribution of the periods betwen two signals following one other is affected by the dead-time of the detector. The simple electronic circuit designed can be linked to the output of the pre-amplifier....
The algorithm is quite general and completelyindependent of the particular nature of the measured signal. It can alsobe applied to any other single-event counting measurement with detectorand/or electronics dead-time. 展开 DOI: 10.1364/OE.24.009429 被引量: 5 ...
detector to measure the neutron multiplicity probability distribution of various fissioning nuclides were reported by Diven2and Hopkins3. In these experiments, a dead-time correction was introduced to account for a single pulse overlap, i.e. two events with a time difference smaller than the dead...
ToF-SIMS spectra are formed by bombarding a surface with a pulse of primary ions and detecting the resultant ionized surface species using a time-of-flight mass spectrometer. Typically, the detector is a time-to-digital converter. Once an ion is detected using such detectors, the detector becom...
And in another goroutine the order of locks is reversed: B.Lock()// defer B.Unlock() or similar...A.Lock()// defer A.Unlock() or similar. This does not guarantee a deadlock (maybe the goroutines above can never be running at the same time), but it is bad practice. Detection...
timeouts are the only mechanism by which deadlocks will be broken. If the deadlock detector has been configured with a different option, then regular deadlock detection will be performed, and in addition, if timeouts have also been specified, lock requests and transactions will time out as well...
