Properties of CsI and CsI-TMAE photocathodes

Properties of reflective and semitransparent CsI photocathodes

Various aspects related to the quantum efficiency of the reflective and semitransparent CsI photocathodes have been investigated experimentally . The investigation explored the dependence of the quantum efficiency on the following: the thickness of the photocathode film, the gas used in the parallel-plate avalanche chamber, exposure to water vapor, and the density of the CsI film . With reflect...

Testing of CsI Photocathodes Efficiencies in a Liquid Xenon Chamber

A summary of the Dark Matter problem and a more detailed overview of the WIMP/neutralino direct detection are introduced. More specifically the XENON – a next generation direct detection detector of WIMPs – is described. A detailed description is given on the techniques used in the current experiment to produce CsI photocathodes. Furthermore the tests done to check the performance of the CsI ph...

Summarn Recognition of psychological distress in patients with cancer. some of which can be ameliorated With appropriate intervention. is a crucial aspect of patient care. Previous studies, with the exception of one. indicate that oncologists often fail to detect general distress and do not identify those patients with significant psychological disorder. As approximately 25-30% of patients expe...

Heat enhancement of radiation resistivity of evaporated CsI, KI and KBr photocathodes

The photoemissive stability of as-deposited and heat-treated CsI, KI and KBr evaporated thin "lms under UV radiation is examined in this paper. After the deposition, some photocathodes were annealed for several hours at 903C in vacuum and their performance was then compared to the performance of non-heated samples. We observed that the post-evaporation thermal treatment not only increases the p...
