Simplified PMT Model
نویسنده
چکیده
At Drexel University, I was testing the 8-inch, 13 stages, R1408 PMTs which will be used for the inner vetos of the Double Chooz experiment [1]. These PMTs were used in the IMB [2] and SuperKamiokande [3] experiments. This testing allowed a better understanding of their working. In this paper I propose a model inspired from observations during the testing period. The first aim of this model is to explain in simple way the saturation characteristics of the PMT. The Model gives a global description of how the different PMTs characteristics, like the quantum efficiency (QE) or the collectivity efficiency (CE), are linked together to the PMT gain (G). The model is compared to the data obtained from three different PMTs, which have different single photoelectron (spe) distributions.

An Exact Formula to Describe the Amplification Process in a Photomultiplier Tube
An analytical function is derived that exactly describes the amplification process due to a series of discrete, Poisson-like amplifications like those in a photo multiplier tube (PMT). A numerical recipe is provided that implements this function as a computer program. It is shown how the program can be used as the core-element of a faster, simplified routine to fit PMT spectra with high efficie...

OBJECTIVE To describe the application and evaluation of Pneumonia Management Tool (PMT) to manage children with non-severe pneumonia (NSP) at the first level health care (FLHC) facilities according to the standard case management (SCM) guidelines for acute respiratory infections (ARI). METHOD The ARI SCM guidelines were simplified to a PMT and used by health workers at 14 FLHC facilities to a...
متن کاملA Scale-up Design Procedure for Rotating Biological Contactors
A scale-up design procedure, based on a new physical mass transfer (PMT) model, whichdescribes the performance, for aerobic rotating biological contactors (RBC’s) is developed. This scale-up procedure can be used to determine the disc surface area needed to prevent an oxygen limitation or to obtain a specific degree of treatment. In contrast to the empirical, and most previous RBC performance m...
متن کاملVirulence of the fungal pathogen Candida albicans requires the five isoforms of protein mannosyltransferases.
The PMT gene family in Candida albicans encodes five isoforms of protein mannosyltransferases (Pmt proteins Pmt1p, Pmt2p, Pmt4p, Pmt5p, and Pmt6p) that initiate O mannosylation of secretory proteins. We compared virulence characteristics of pmt mutants in two complex, three-dimensional models of localized candidiasis, using reconstituted human epithelium (RHE) and engineered human oral mucosa (...
