Abstract

Booster operation for collider physics is considerably different than for fixed target operation. Various scenarios for collider physics, machine studies, and P-Bar targeting may require that the intensity vary from 5E10 PPP to 3E12 PPP at a 15 Hertz machine cycle rate. In addition to the normal Booster single turn extraction mode, collider operations require that the Booster inject into the Main Ring a small number of beam bunches for coalescing into a single high intensity bunch. These bunches must be synchronized such that the center bunch arrives in the RF bucket which corresponds to the zero phase of the coalescing cavity. The system implemented has the ability to deliver a precise fraction of the available 84 Booster beam bunches to Main Ring or to the P-Bar Debuncher via the newly installed AP-4 beam line for tune-up and studies. It is required that all of the various intensity and extraction scenarios be accommodated with minimal operator intervention.

Some Suggested Techniques for Achieving Required Main Ring Low Level RF Performance for the Tevatron I Program

Technical Report Griffin, J. E. ; MacLachlan, J.

These techniques are derived from experience with the existing low level rf system and from the results of accelerator experiments directed at the Tev I requirements which were performed using a specially modified low level rf system. The techniques suggested here are not necessarily unique and other techniques may be acceptable. It is important to realize that certain performance requirements on the Booster and Main Ring are substantially different in the Tev I program from those which have been acceptable in the fixed target program. For example, the longitudinal emittance of the bunches has been routinely and intentionally blown upmore »« less

RF cogging in the FNAL Booster Accelerator

Conference William A. Pellico and Robert C. Webber

The Fermilab Booster operates at a Radio Frequency (RF) harmonic number of 84 with beam in all buckets. One or two bunches of beam are systematically lost in the 8 GeV extraction process as beam is swept across a magnetic septum during the extraction kicker rise time. The prompt radiation and component activation resulting from this localized high energy beam loss become serious concerns as Booster beam throughput must be increased more than tenfold to meet the requirements of RUN II, NUMI, and MiniBooNE experiments. Synchronizing a gap in the beam to the firing of the extraction kickers, a relativelymore »« less

Synchronous transfer of beam from the booster to the main ring in the KEK proton synchrotron

Conference Kimura, Y ; Kawakubo, T ; Takata, K ; ... - IEEE Trans. Nucl. Sci.; (United States)

The KEK main ring is filled with nine successive beam pulses from the fast cycling booster synchrotron during the injection. Booster bunches are synchronously transferred into stationary rf buckets of the main ring preserving the booster rf structure. At the transfer, longitudinal phase and momentum of the beam bunch extracted from the booster are matched to those defined in the main ring within errors of Vertical bar Delta Phi Vertical bar approximately 10/sup 0/ and Vertical bar Delta p/p Vertical bar approximately 4 x 10/sup -4/.
Design of a High Luminosity 100 TeV Proton Antiproton Collider

Thesis/Dissertation Oliveros Tuativa, Sandra Jimena

Currently new physics is being explored with the Large Hadron Collider at CERN and with Intensity Frontier programs at Fermilab and KEK. The energy scale for new physics is known to be in the multi-TeV range, signaling the need for a future collider which well surpasses this energy scale. A 10$$^{\,34}$$ cm$$^{-2}$$ s$$^{-1}$$ luminosity 100 TeV proton-antiproton collider is explored with 7$$\times$$ the energy of the LHC. The dipoles are 4.5\,T to reduce cost. A proton-antiproton collider is selected as a future machine for several reasons. The cross section for many high mass states is 10 times higher in $$p\bar{p}$$more »« less

Computer Simulation of Antiproton RF Stacking in the Precooler Ring

Technical Report Takayama, K. ; Ruggiero, A. G.

It has been recently proposed a scheme to produce a high-intensity antiproton beam in a precooler ring with functions of both stochastic cooling and accumulating. According to this scheme 13 batches from {bar p}-target are stacked and precooled on the stacking orbit every Main Ring cycle. After that the precooled beam is transported in a second storage ring (the Accumulator) and cooled for several hours together with previous {bar p} batches. As alternative it has also been proposed to decelerate each precooler pulse down to 200 MeV at which energy it can be transferred in a modified Electron Cooling Ringmore »« less
