[en] SABER (the South Arc Beam Experimental Region) is a proposed facility for experiments with 30 GeV electron and positron beams from the SLAC linac. The combination of a short bunch length (s_z ∼ 30 microns), high beam charge (3 nC), and small focal spot size (s_r = 10 microns) will offer unique scientific opportunities. For more detailed information about the SABER facility and an overview of some of the science possible take a look at the SABER proposal. Initial experiments with electrons could start as early as 2007. A central goal of SABER is to provide a facility responsive to the research needs of its users. The workshop's purposes are to introduce SABER to the potential user community and to explore the range of experiments that are possible. This is an opportunity for the research community to provide input about science at SABER and on the required beam parameters and infrastructure

[en] The general effects of the recent Mexican election on that country's socio-economic development are discussed. Future directions of the new government include a trend toward greater deregulation, more privatization, and a greater importance of social welfare policies. The Mexican climate for new investment appears positive; the first half of 1994 saw $8 billion of foreign investment in Mexico. Canadian investment in Mexico dates from the 1850s and Mexico is now Canada's largest economic and trading partner in Latin America. Canada-Mexico trade is expected to rise to over $8 billion/y by 2000. To assist in this relationship, a Canadian Business Centre was opened in Mexico City in 1994 and programs are in place to aid potential Canadian exporters. The implications of the above developments for the oil and gas industry are examined. The Mexican state oil monopoly PEMEX is concentrating on core activities (extraction and refining of oil) and has sold almost all of its secondary petrochemical business. Private contractors can now obtain drilling contracts. PEMEX plans to invest ca $23 billion between now and 2000 and it is likely that at least some of this investment will come via partnerships between private firms and government. This is especially possible in the natural gas sector, where supply and demand are essentially in balance. Gas production will likely increase 60-80% by 2001 and Canadian companies are well suited to help bring this about. Some Canadian firms such as Novacorp and Associated Pipeline Services are already doing business with PEMEX or participating in joint ventures with Mexican firms. Suggestions are offered for doing business in Mexico

[en] The critical parameters which limit the luminosity of the Fermilab Tevatron Collider are the beam emittances, both longitudinal and transverse, at each stage in the acceleration sequence. Improvements to reduce invariant emittance growth at earlier acceleration stages necessarily encourage improvements in all downstream stages. Recent advances in linac technology should permit a significant increase in the beam brightness of the Fermilab linac. A redesign of the low energy section of the linac is envisioned to include a circular aperture H/sup /minus// source, a short 30-keV transport line (solenoids, Gabor lenses or einzel lenses) for matching to a radio frequency quadrupole linac (RFQ), and injection at approximately 2 MeV into a new 200 MHz Alvarez linac tank for acceleration to 10 MeV. 9 refs., 1 fig

[en] The NLC Test Accelerator (NLCTA) at SLAC was built to address various beam dynamics issues for the Next Linear Collider. An S-Band RF gun is being installed together with a large-angle extraction line at 60 MeV followed by a matching section, buncher and final focus for the laser acceleration experiment, E163. The laser-electron interaction area is followed by a broad range, high resolution spectrometer (HES) for electron bunch analysis. Another spectrometer at 6 MeV will be used for analysis of bunch charges up to 1 nC. Emittance compensating solenoids and the low energy spectrometer (LES) will be used to tune for best operating point and match to the linac. Optical symmetries in the design of the 25.5^o extraction line provide 1:1 phase space transfer without use of sextupoles for a large, 6D phase space volume and range of input conditions. Design techniques, tolerances, tuning sensitivities and orthogonal knobs are discussed

Recent advances in linac technology should permit a significant increase in the beam brightness of the Fermilab linac.

[en] A linac injector for a new proton source complex at Fermilab is assumed to have a kinetic energy of 1 GeV. This linac would be sized to accelerate 100 mA of H^- beam in a 200 microsecond pulse at a 15 Hz repetition rate. This would be adequate to produce ∼10¹⁴ protons per pulse allowing for future improvements of the new proton source complex. An alternate proposal is to add 600 MeV of side coupled cavity linac at 805 MHz to the existing 400 MeV Linac. This addition may either be in a new location or use the present Booster tunnel. A discussion of these possibilities will be given

[en] Commissioning of the Fermilab High Energy Linac during September and October of 1993 has increased the energy of the H- linac from 200 to 400 MeV. The Linac Upgrade is one portion of the Fermilab Upgrad and is intended to reduce the incoherent space-charge tuneshift at injection into the 8 GeV Booster. To accomplish this increase in energy within the existing enclosure, four 201.25 MHz drift-tube linac tankshave been replaced by seven 805 MHz side-coupled cavity modules to accelerate the beam from 116 MeV to 400 MeV. Each module is driven with a klystron amplifier delivering 10 MW of peak power for 60 μsec with a maximum pulse repetition rate of 15 Hz. Nominal beam current is 35 mA with a pulselength of 40 μsec. Results from commissioning and operational experience during Fermilab Collider Run 1B are presented

[en] We present a technique for calculating the power coupling efficiency for a laser-driven photonic bandgap structure using electromagnetic finite element simulations, and evaluate the efficiency of several coupling scenarios for the case of a hollow-core photonic bandgap fiber accelerator structure.

[en] The NLC Test Accelerator (NLCTA) was built to address beam dynamics issues for the Next Linear Collider and beyond. An S-Band RF gun, diagnostics and low energy spectrometer (LES) at 6 MeV together with a large-angle extraction line at 60 MeV have now been built and commissioned for the laser acceleration experiment, E163. Following a four quad matching section after the NLCTA chicane, the extraction section is followed by another matching section, final focus and buncher. The laser-electron interaction point (IP) is followed by a broad range, high resolving power spectrometer (HES) for electron bunch analysis. Optical symmetries in the design of the 25.5 degree extraction line provide 1:1 phase space transfer without sextupoles for a large, 6D phase space volume and range of input conditions. Spot sizes down to a few microns at the IP (HES object) allow testing microscale structures with high resolving power at the HES image. Tolerances, tuning sensitivities, diagnostics and the latest commissioning results are discussed and compared to design expectations

[en] An experimental effort is currently underway at the E-163 test beamline at Stanford Linear Accelerator Center to use a hollow-core photonic bandgap (PBG) fiber as a high-gradient laser-based accelerating structure for electron bunches. For the initial stage of this experiment, a 50pC, 60 MeV electron beam will be coupled into the fiber core and the excited modes will be detected using a spectrograph to resolve their frequency signatures in the wakefield radiation generated by the beam. They will describe the experimental plan and recent simulation studies of candidate fibers.
