FPGA-Based Pulse Pile-Up Correction With Energy and Timing Recovery

Iterative correction for ‘pile-up’ in single-photon lifetime measurement

A novel iterative algorithm is proposed to correct for pulse, or photon, ‘pile-up’ in the measurement of temporal intensity profiles using time-correlated single-photon counting (TCSPC). Despite the existence of correction algorithms since 1968, most TCSPC experiments are operated in a very low photon-count mode to avoid pulse pile-up effects in the data. This is inefficient and time-consuming,...

A Monte Carlo Code for Simulation of Pulse Pile-up Spectral Distortion in Pulse-height Measurement

The Monte Carlo simulation code CEARPPU has been improved to obtain better accuracy for predicting pulse-height spectra measured at high counting rates. Experimental verification was carried out by measuring an Fe-55 spectrum with a Si(Li) X-ray spectrometer. Based on the spectrum measured at low counting rate, which is considered to be the “true” spectrum with no pulse pile-up distortion, the ...

Pile-up glass microreactor.

We made a 'pile-up' microreactor in which ten levels of microchannel circuits were integrated to form a single glass entity. Solutions were distributed to each layer via cylindrical holes with a diameter much larger than that of the microchannel. Fabrication of the pile-up reactor was completed using only conventional photolithography, wet etching and thermal bonding techniques, and no special ...

Fpga Based L - Band Pulse Doppler Radar

Avoiding prepositional pile-up

After receiving research ethics approval from the review boards at three teaching hospitals affiliated with two universities in urban Ontario, Canada, we asked clinical and educational leaders in each hospital to identify inter-professional clinical health care teams with reputations for strong collaborations and managerial/administrative support. These prepositions require the reader to sift t...
