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...

Pep-ii Status*

PEP-II and BaBar have just finished run 7, the last run of the SLAC B-factory. PEP-II was one of the few highcurrent e+ecolliding accelerators and holds the present world record for stored electrons and stored positrons. It has stored 2.07 A of electrons, nearly 3 times the design current of 0.75 A and it has stored 3.21 A of positrons, 1.5 times more than the design current of 2.14 A. Highcurr...

PEP-II Status Report

The main design features of the PEP-II asymmetric two-ring electronpositron B Factory collider, built at the Stanford Linear Accelerator Center, are described. This facility will complete construction in June 1998. The high energy ring, completed in May 1997, has had 3 months of commissioning and successfully stored 0.75 A of electrons. The success of the high energy ring testing validates not ...
