Tune Measurement at the Tevatron
نویسنده
چکیده
The Tevatron is a single beam pipe machine which contains both protons and anti-protons for HEP. This poses a challenge for measuring betatron tunes because of the possibility of contamination from the other species. In order to overcome this problem, stripline type structures are usually used because they are directional by construction or for the case of the 21.4 MHz Schottky system, a clever method is used to distinguish between the two. In the Tevatron, tunes are measured primarily with two instruments: the 21.4 MHz and the 1.7 GHz Schottky systems. Two other systems currently in development are the 3D-BBQ (direct diode detection baseband tune) system and a direct digitization technique which gives very fast bunch by bunch tunes.

Fermi National Accelerator Laboratory FERMILAB-Conf-96/340 Beam Beam Tune Shifts for 36 Bunch Operation in the Tevatron
We are preparing to upgrade the Tevatron Collider from 6 to 36 bunch operation. The 36 bunches are in 3 “trains” of 12 bunches. The spacing between bunches within a train is 21 RF buckets (53.106 MHz) and 139 empty buckets separate the trains. Because the 36 bunches are not evenly spaced around the machine, the different bunches within a train pass the opposing bunches at different points in th...
متن کاملCalculation of Nonlinear Tune Shift Using Beam Position Measurement Results
The calculation of the nonlinear tune shift with amplitude based on the results of measurements and the linear lattice information is discussed. The tune shift is calculated based on a set of specific measurements and some extra information which is usually available, namely that about the size and particle distribution in the beam and the linear optics effect on the particles. The method to so...
متن کاملRealtime Tune Measurements in Slow-cycling Accelerators
Measurement and control of the tunes, coupling, and chromaticities in storage rings is essential to efficient operation of these accelerators. Yet it has been very difficult to make reliable realtime measurements of these quantities. We have built and commissioned the microprocessorbased Generic Finite State Data Acquisition (GFSDA) system. GFSDA provides turn-by-turn data acquisition and analy...
متن کاملCompensation of Beam-beam Effects in the Tevatron Collider with Electron Beams
The beam-beam interaction in the Tevatron collider sets limits on bunch intensity and luminosity. These limits are caused by a tune spread in each bunch which is mostly due to head-on collisions, but there is also a bunch-to-bunch tune spread due to parasitic collisions in multibunch operation. We propose to compensate these effects with use of a countertraveling electron beam, and present gene...

In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functions by using Altrali-Parisi equation. Also, we have calculated the transverse momentum distributions of the differential cross sections . Our results...
