Z&AC-PUB-ZOO July 1966 HIGH ENERGY TRIDENT PRODUCTION WITH DEFINITE HELICITIES*

Electron-Positron Pair Production in the Deep Quantum Regime

Electron-positron pair production via real and virtual photons is signi cant to the design of linear colliders, especially in the deep quantum regime (i.e., beamstrahlung parameter >> 1). In this regime, pair production via a virtual photon (the trident process) can become comparable in rate to pair production via a real beamstrahlung photon. We derive characteristics of the e+epairs produced v...

SLAC -PUB-240 November 1966 DESIGN CONSIDERATIONS FOR HIGH ENERGY ELECTRON-POSITRON STORAGE RINGS*

SLAC -PUB-233 October 1966 THE STANFORD TWO-MILE LINEAR ACCELERATOR*

In April 1957, Stanfc:rd University proposed the construction of a two-mile long linear electron accelerator capable of accelerating electrons to energies of 10 to 20 CeV for use in physics research. Congressional authorization for this machine was given in September 1961, and construction of the Stanford Linear Accelerator Center (SLAC) started in July 1962 on 480 acres of land near Stanford U...

Relativistic positron production with ultra-intense short-pulse lasers

Ultra-intense laser interactions with solid foils are studied as a means to produce relativistic positron plasmas, which has been proposed as a potential laboratory for understanding positron-electron plasma aspects of gamma-ray bursts [1]. Initial experiments with high energy Nd:glass lasers have revealed a strong dependence of the positron yield, and energy distribution, on the thin-foil targ...

SLAC-PUB-454 July 1968 QUANTUM ELECTRODYNAMICS: THEOFY

At the last International High Energy Physics Conference in 1966 the speaker on this same topic of quantum electrodynamics concluded with these remarks: ‘IBy now I have strayed very far from the usual energy domain of 10mFIO eV for a high energy conference to 10Wg eV in discussing a missing few tenths of a MHz in the Lamb shift. In fact, both domains are important in probing the detailed behavi...
