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...
متن کاملPep-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...
متن کاملPEP-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 ...
متن کاملPEP - II at 1
PEP-II is an asymmetric e -e collider operating at the Υ 4S energy and has recently set several performance records. The luminosity has reached a peak of 1 2 1034/cm2/s. Operating in continuous injection mode for both beams PEP-II has delivered up to 0.91/fb/day. Peak currents have reached 3.0 A of positrons and 1.9 A of electrons in 1732 bunches. Total delivered luminosity since turn-on in 199...
متن کاملPEP-II IR-2 Alignment
This paper describes the first results and preliminary analysis obtained with several alignment monitoring systems recently installed in the PEP-II interaction region. The hydrostatic level system, stretched wire system, and laser tracker have been installed in addition to the existing tiltmeters and LVDT sensors. These systems detected motion of the left raft, which correlated primarily with t...
