چکیده
In this study, we present the large photomultiplier tube (PMT) afterpulse measurement results obtained from Jiangmen underground neutrino observatory (JUNO) experiment. A total of 11 dynode-PMTs (R12860) Hamamatsu company (Hamamatsu Photonics K.K. (HPK)) and 150 micro-channel plate PMTs (MCP-PMTs, GDB-6201) NNVT (North Night Vision Technology Co., Ltd. (NNVT)) were tested. Subsequently, an model was built according to time distribution probability occurrence for these two types PMTs. The average ratio charge with a delay between 0.5 $$\upmu$$ s 20 primary pulse is $$\sim$$ 5.7% (13.2%) tested MCP-PMTs (dynode-PMTs). JUNO experiment will deploy 20,012 20-inch PMTs; study benefit detector simulation, event reconstruction, data analysis regarding

Multispectral analysis of Asteroid 3 Juno taken with the 100-inch telescope at Mount Wilson Observatory
High-resolution multispectral images of main-belt asteroid 3 Juno were taken at visible and near-IR wavelengths with the 100-inch telescope at Mount Wilson Observatory equipped with an adaptive optics system. The images show spectral features that may represent a large relatively recent impact that deeply excavated the coarse-grained olivine–pyroxene-rich crust of the asteroid. © 2003 Elsevier ...
متن کاملNorth-Holland Publishing Company 20 INCH DIAMETER PHOTOMULTIPLIER
In the field of large scale water Cherenkov experiments such as proton decay, the detector is required to have a wide photosensitive area, high gain, low noise, fast timing, and good stability. The 20 inch diameter photomultiplier is developed and ascertained to have good characteristics as the detector component of the proton decay experiment. In this paper, various characteristics of the newl...
متن کاملSignal Recovery with PMTs
In general, the choice between boxcar averaging (gated integration) and lock-in detection (phase sensitive detection) is based on the time behavior of the signal. If the signal is fixed in frequency and has a 50 % duty cycle, lock-in detection is best suited. This type of experiment commonly uses an optical chopper to modulate the signal at some low frequency. Signal photons occur at random tim...
متن کاملIzumo meets Juno
Sexual reproduction ensures the continued propagation of almost all eukaryotic species. Two morphologically very different types of cell, which develop exclusively in either the male or female, perform the role of creating a new and genetically distinct organism. In mammals, these 2 haploid cells, the sperm and the egg, meet in the female reproductive tract, interact, and finally fuse to become...
متن کاملSignificantly improved lifetime of Microchannel Plate PMTs∗
The main particle identification devices of the PANDA experiment will be two DIRCs placed around (barrel) and downstream (disc) of the target. The preferred photon sensor option are microchannel plate (MCP) PMTs because they can be operated inside the 2 Tesla magnetic field of the solenoid. Furthermore, these multi-anode sensors are rather compact and show a superior time resolution which is ty...
