Two different systems have been built to study the geomagnetic field effect on performance of large area photomultiplier tubes. The main characteristics tubes such as gain, collection efficiency, transition time spread and energy resolution were measured investigate effect. This shows that both dynode structure orientation a influence due Different methods proposed tested reduce these effects. ...

Hamamatsu R5900-00-M64 and R7600-00-M64 photomultiplier tubes will be used with wavelength–shifting optical fibres to read out scintillator strips in the MINOS near detector. We report on measurements of the gain, efficiency, linearity, crosstalk, and dark noise of 232 of these PMTs, of which 219 met MINOS requirements.

A facility to test the photomultiplier tubes (PMTs) for the solar neutrino detector Borexino was built at the Gran Sasso laboratory. Using the facility 2200 PMTs with optimal characteristics were selected from the 2350 delivered from the manufacturer. The details of the hardware used are presented. r 2004 Published by Elsevier B.V.

This article discusses detectors (more precisely: sensors), that are employed in single point, i.e. true confocal scanning microscopes. The sensors in such systems are usually photomultiplier tubes. Also, the silicon pendants of PMTs are used for particular applications, especially single-molecule measurements. A new development has led to chimeric devices called hybrid detector (HyD) which uni...

1 Abstract This report presents some recent data on tests on photomultiplier tubes (PMT's) carried out at the University of Oxford. The standardized testing procedures have been extensively documented in another report [1] which describe the 'Mortar' apparatus and the conditions used.

Abstract The focal plane camera is the core component of Wide Field-of-view Cherenkov/fluorescence Telescope Array (WFCTA) Large High-Altitude Air Shower Observatory (LHAASO). Because capability working under moonlight without aging, silicon photomultipliers (SiPM) have been proven to be not only an alternative but also improvement conventional photomultiplier tubes (PMT) in this application. E...

The borosilica, a very common PMT window and envelope material, contains 5% Boron (1% 10B). The high cross section for 10B capturing thermal neutrons (3980 barn), is a concern for LHC experiments using borosilica window PMTs. This study investigates the rate and the size of the signals generated by thermal neutron boron interaction in borosilica window PMTs; Hamamatsu R7525-HA and R7600U-200-M4...
