Available in PDF, EPUB and Kindle. Book excerpt: A compact table-top 20-GW 50-ps CO2 laser system is in operation for strong-field physics studies at the ATF. We propose scaling up of the picosecond CO2 laser to a terawatt peak power level to meet the requirements of advanced laser accelerators. Computer modeling shows that a relatively compact single-beam picosecond CO2 laser system with a high-pressure x-ray picosecond amplifier of a 10-cm aperture is potentially scalable to the (approximately)1-TW peak power level.

This book was released on 1996 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first terawatt picosecond C02 laser system is under development at the Brookhaven Accelerator Test Facility. Presently operational 1 Joule 100-ps ATF laser will be upgraded with a 10 atm amplifier capable of delivery (approximately) 15 Joules of laser energy in a 3 ps pulse. We describe the design of the x-ray preionized 10 atm amplifier of a 10 liter active volume energized by a 1 MV, 200 kA transverse electric discharge. The amplifier, equipped with internal optics, permits the accommodation of a regenerative stage and a multi-pass booster in a relatively compact single discharge volume. The ATF terawatt C02 laser shall become operational in 1997 to serve for laser acceleration, x-ray generation and other strong-field physics experiments.

Download or read book Emerging Terawatt Picosecond CO2 Laser Technology and Possible Applications in Accelerator Physics written by and published by . This book was released on 1997 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first terawatt picosecond (TWps) CO2 laser is under construction at the BNL Accelerator Test Facility (ATF). TWps-CO2 lasers, having the order of magnitude longer wavelength than the well-known table-top terawatt solid state lasers, offer new opportunities for the strong-field physics research. For processes based on electro quiver motion, such as laser wakefield acceleration (LWFA), the advantage of the new class of lasers is due to a gain of two orders of magnitude in the ponderomotive potential for the same peak power. The large average power capability of CO2 lasers is important for the generation of hard radiation through Compton back-scattering of the laser off energetic electron beams, as well as for other applications. Among them are: LWFA modules of a tentative electron-positron collider, [gamma]-[gamma] (or [gamma]-lepton) collider, a possible table-top source of high-intensity x-rays and gamma rays and the generation of polarized positron beams.

Available in PDF, EPUB and Kindle. Book excerpt: Demonstration of ultra-high acceleration gradients in the SM LWFA experiments put a next objective for the laser accelerator development to achieve a low-emittance monochromatic acceleration over extended interaction distances. The emerging picosecond terawatt (ps-TW) CO2 laser technology helps to meet this strategic goal. Among the considered examples are: the staged electron laser accelerator (STELLA) experiment, which is being conducted at the Brookhaven ATF, and the plasma-channeled LWFA. The long-wavelength and high average power capabilities of CO2 lasers maybe utilized also for generation of intense x-ray and gamma radiation through Compton back-scattering of the laser beams off relativistic electrons. We discuss applications of ps-TW CO2 lasers for a tentative [gamma]-[gamma] (or [gamma]-lepton) collider and generation of polarized positron beams.

Available in PDF, EPUB and Kindle. Book excerpt: A brief overview of laser acceleration techniques and a comparative analysis of the picosecond terawatt (ps-TW) CO2 laser technology versus T3 solid state lasers for prospective HEP applications. Special attention is given to two laser accelerator schemes. The first one is the far-field staged laser accelerator, STELLA, which is under exploration at the ATF using a CO2 laser. The second is a laser wakefield accelerator where ps-TW CO2 lasers have a great potential. Inverse to the laser accelerator, a prospective monochromatic x-ray source feasible at the ATF will also utilize a 50 MeV subpicosecond electron beam and the first ps-TW CO2 laser, PITER I.

Available in PDF, EPUB and Kindle. Book excerpt: Extended cylindrical plasma channels produced under gas breakdown by axicon-focused laser beams may be used as optical waveguides in laser-driven electron accelerators. Plasma channeling of the laser beams will help to maintain a high acceleration gradient over many Rayleigh lengths. In addition, the rarefied gas density channel produced after the optical gas breakdown, and followed by a plasma column expansion, reduces multiple scattering of the electron beam. A high-power picosecond C02laser operational at the ATF and being further upgraded to the 1 TW level is considered as the source for a plasma channel formation and as the laser accelerator driver. We show how various laser accelerator schemes including beat wave, wake field, and Inverse Cherenkov accelerator benefit from using a channeled short-pulse C02laser as a driver.

Book excerpt: Short-pulse, high-power C02 lasers open new prospects for development of high-gradient laser-driven electron accelerators. The advantages of [lambda]=10 [mu]m CO2 laser radiation over the more widely exploited solid state lasers with [lambda]≈1 [mu]m are based on a [lambda]2-proportional ponderomotive potential, [lambda]-proportional phase slippage distance, and %-proportional scaling of the laser accelerator structures. We show how a picosecond terawatt C02 laser that is under construction at the Brookhaven Accelerator Test Facility may benefit the ATFs experimental program of testing far-field, near-field, and plasma accelerator schemes.

The experimental results are compared with computer program TRANSPORT simulations.
