Differential Relationships Between Momentum Magnetic Field, Orbit Length, and Revolution Frequency

Description: The purpose of this memo is to put down, in one place, a number of commonly used accelerator formulae. I'll also comment briefly on the derivation of these relationships. Nothing in this memo is my original work. All of this was developed many years ago by the brilliant founders of the field of Accelerator Physics. The widely used differential relationships between beam momentum (p), dipole magnetic field (B), orbit length (L), and revolution frequency (f) are given in Table 1.

The Tevatron Ionization Profile Monitors

Description: In designing an ionization profile monitor system for the Tevatron some novel approaches were taken, in particular for the readout electronics. This was motivated by the desire to resolve the individual bunches in both beams simultaneously. For this purpose, custom made electronics originally developed for Particle Physics experiments was used to provide a fast charge integration with very low noise. The various parts of the read-out electronics have been borrowed or adapted from the KTev, CMS,… more

The US Muon Accelerator Program (MAP)

Description: The US Department of Energy Office of High Energy Physics has recently approved a Muon Accelerator Program (MAP). The primary goal of this effort is to deliver a Design Feasibility Study for a Muon Collider after a 7 year R&D program. This paper presents a brief physics motivation for, and the description of, a Muon Collider facility and then gives an overview of the program. I will then describe in some detail the primary components of the effort.

Some physics issues of carbon stripping foils

Description: Carbon foils are widely used in charge-exchange injection in high intensity hadron accelerators. There are a number of physics issues associated with the use of carbon foils, including stripping efficiency, energy deposition and foil lifetime (temperature rise, mechanical stress and buckling, etc.). This paper will give a brief discussion of these issues.

The US Muon Accelerator Program

Description: An accelerator complex that can produce ultra-intense beams of muons presents many opportunities to explore new physics. A facility of this type is unique in that, in a relatively straightforward way, it can present a physics program that can be staged and thus move forward incrementally, addressing exciting new physics at each step. At the request of the US Department of Energy's Office of High Energy Physics, the Neutrino Factory and Muon Collider Collaboration (NFMCC) and the Fermilab Muon C… more

The D0 run II trigger system

Description: The D0 detector at the Fermilab Tevatron was upgraded for Run II. This upgrade included improvements to the trigger system in order to be able to handle the increased Tevatron luminosity and higher bunch crossing rates compared to Run I. The D0 Run II trigger is a highly exible system to select events to be written to tape from an initial interaction rate of about 2.5 MHz. This is done in a three-tier pipelined, buffered system. The first tier (level 1) processes fast detector pick-off signals … more

Calculating emittance for Gaussian and Non-Gaussian distributions by the method of correlations for slits

Description: One common way for measuring the emittance of an electron beam is with the slits method. The usual approach for analyzing the data is to calculate an emittance that is a subset of the parent emittance. This paper shows an alternative way by using the method of correlations which ties the parameters derived from the beamlets to the actual parameters of the parent emittance. For parent distributions that are Gaussian, this method yields exact results. For non-Gaussian beam distributions, this met… more

Demonstration of Transverse-to-Longitudinal Emittance Exchange at the Fermilab Photoinjector

Description: Phase space manipulation techniques within two degrees of freedom are foreseen to enhance the performances of next generation accelerators such as high-energy physics colliders and accelerator based light sources. At the Fermilab A0 photoinjector, a proof-of-principle experiment to demonstrate the exchange of the transverse and longitudinal emittances is ongoing. The emittance exchange beamline consists of a 3.9 GHz normal conducting deflecting mode cavity flanked by two doglegs. Electron bunch… more

Upgrade of Fermilab/NICADD photo injector laboratory

Description: The Fermilab/NICADD photoinjector laboratory is a 16 MeV electron accelerator dedicated to beam dynamics and advanced accelerator physics studies. FNPL will soon be capable of operating at {approx} 40 MeV, after the installation of a high gradient TESLA cavity.

Measurement of Littlest Higgs Model Parameters

Description: The effects of the extended gauge sector present in the Littlest Higgs model in the reactions e{sup +}e{sup -} {yields} f{bar f} and e{sup +}e{sup -} {yields} Zh are examined. We find that the search reach at the 500 GeV ILC essentially covers the entire region where this model is relevant to the hierarchy proble and extends the reach of the LHC. In addition, we show that the ILC allows for an accurate determination of the model parameters, to the precision of a few percent, provided that the L… more

Betatron motion with coupling of horizontal and vertical degrees of freedom

Description: Presently, there are two most frequently used parameterizations of linear x-y coupled motion used in the accelerator physics. They are the Edwards-Teng and Mais-Ripken parameterizations. The article is devoted to an analysis of close relationship between the two representations, thus adding a clarity to their physical meaning. It also discusses the relationship between the eigen-vectors, the beta-functions, second order moments and the bilinear form representing the particle ellipsoid in the 4D… more

Facing these new demands, the topic of phase space gymnastics is becoming a new focus of accelerator physics R&D. In a phase space gymnastics, the beam's phase space distribution is manipulated and precision tailored to meet the required beam qualities. On the other hand, all realization of such gymnastics will have to obey accelerator physics principles as well as technological l… more
