SPEAR II and PEP Klystron Parameters PEP Klystron Interaction Space Parameters SPEAR II PEP

The 125 kW CW klystrons to be described in the first part of this paper were specifically designed for energy upgrading of the electron-positron storage ring, SPEAR II, at SLAC. Four tubes are required with an efficiency greater than 50 percent. The operating frequency is 358.54 MHz. The gain is approximately 50 dB, the operating voltage is 41 kV and the microperveance is 0.7. The klystron must...

How do Named Entities Contribute to Retrieval Effectiveness?

Named entities in topics are a major factor contributing to the quality of retrieval results. In this paper, we report on an analysis on the correlation between the number of named entities present in a topic and the retrieval quality achieved for these topics by retrieval systems within CLEF. We found that a medium positive correlation exists for German, English and Spanish topics. Furthermore...

Learning to Recognize Discontiguous Entities

This paper focuses on the study of recognizing discontiguous entities. Motivated by a previous work, we propose to use a novel hypergraph representation to jointly encode discontiguous entities of unbounded length, which can overlap with one another. To compare with existing approaches, we first formally introduce the notion of model ambiguity, which defines the difficulty level of interpreting...
