(SBIR) DOE - Advanced Concepts And Technology For High Energy Accelerators Primary Sponsor: Department of Energy Deadline: 2/20/2001 The Department of Energy (DOE) High Energy Physics program supports a broad research and development (R&D) effort in the science, engineering, and technology of charged particle accelerators, storage rings, and associated apparatus. Advanced R&D is needed in support of this program in the following areas: (1) new concepts for acceleration, (2) novel device and instrumentation development, (3) inexpensive electron sources, and (4) computer software that will contribute to overall advances in accelerator technology applicable to the High Energy Physics program. Relevance to applications in high energy physics must be explicitly described. Advanced accelerator R&D more appropriate to applications in nuclear physics is specifically excluded from this topic and should be submitted under Topic 10. Grant applications which propose using resources of a third party (such as a DOE Laboratory) must include, in the application, a letter of certification from an authorized official of that organization. Grant applications are sought only in the following subtopics: a. New Concepts for Acceleration¾Grant applications are sought to develop new or improved acceleration concepts. Designs should provide very high gradient (>100 MeV/m for electrons or >10 MeV/m for protons) acceleration of intense bunches of particles, or efficient acceleration of intense (>50 mA) low energy (of order <20 MeV) proton beams. One possible concept might include the fabrication of accelerator structures from materials such as Si or SiO2, using integrated circuit technology; in this case, power sources might include lasers in the wavelength range from 1 to 2.5 micrometers. For all proposed concepts, stageability, beam stability, manufacturability, and high wall plug-to-beam power efficiency must be addressed in detail. Grant applications must also address the marketability of any systems, technologies, and devices to be developed. b. Novel Device and Instrumentation Development¾Grant applications are also sought for the development of electromagnetic, permanent magnet, or silicon microcircuit-based charged particle optical elements for particle beam focusing. Examples include, but are not limited to, dipoles, quadrupoles, higher order multipole correctors for use in electron linear accelerators, and solenoids for use in electron-beam or ion-beam sources or for klystron or other radio frequency amplifier tubes operating at wavelengths from 0.1 to 10 cm. In these optical elements, permanent magnets or hybrid magnets incorporating magnetic materials that have very high residual magnetization, radiation resistance, and thermal stability (low variation of field strength with temperature) are of particular interest. Also of interest are field probes for measuring silicon microcircuits with effective apertures down to 5 micrometers. Grant applications are also sought for: (1) novel charged particle beam monitors to measure the transverse or longitudinal charge distribution or emittance, or phase-space distributions of small radius (0.1 micrometers to 5 millimeters diameter), short length (10 micrometers to 10 millimeters) relativistic electron or ion beams; (2) devices capable of measuring and recording the Schottky or transition radiation spectrum of these beams (proposed techniques should be nondestructive or minimally perturbative to the beams monitored and have computer-compatible readouts); and (3) lasers for laser-accelerator applications which provide substantial improvements over currently available lasers in one or more of the following: longer wavelengths (2 to 2.5 micrometers for use with Si transmissive optics), higher power, higher repetition rates or shorter pulse widths. Grant applications are also sought for the development of novel devices and instrumentation for use in the cooling (transverse and longitudinal emittance reduction) of muon beams. Approaches of interest include the development of: concepts or devices for ionization cooling, including emittance exchange processes; instrumentation for muon cooling channels with muon intensities of 1012 muons/pulse; or fast (of order 10 picosecond) timing detectors for muon cooling experiments with low muon intensity (of order 105 muons/second). c. Inexpensive high quality electron sources¾Grant applications are sought for the design and prototype fabrication of small, inexpensive (<$1 million) electron sources for use in advanced accelerator R&D laboratory experiments. The following parameters are target values for accelerator research experiments: (1) energy range of 5 to 35 MeV providing, at a minimum, on the order of 109 electrons in a bunch less than 5 picoseconds long; (2) normalized transverse beam emittance less than or equal to 5 pi mm-mrad; and (3) pulse repetition rate greater than 10 Hz. Grant applications are also sought for significantly lower bunch charges, energies, and emittances but with comparable or greater peak currents and significantly higher repetition rates for bunches from a matrix cathode. Grant applications are sought for the development of radio frequency photocathodes (robust, with quantum efficiencies >0.1 percent) or other novel rf gun technologies operating at output electron beam energies >3 MeV. Laser or electron driven systems for such guns are also sought. Cathodes are needed for vacuum-electronic devices such as klystrons, gyrotrons, and high brightness electron sources for accelerators. Currently, they have many limitations: conventional thermionic cathodes are limited to about 10 amps/cm2; reservoir cathodes can operate at higher temperatures and can deliver up to 40 amps/cm2, but may have life limited by the build-up of deposits from the evaporated barium oxide; photocathodes require expensive lasers, and plasma cathodes have limited life. Therefore, grant applications are sought for research and development leading to rugged, long-life cathodes or electron guns that are capable of producing current densities and currents (several hundred amperes pulsed) comparable to or greater than thermionic emission devices. Applications must focus on one of the following areas of interest: (1) use of secondary emission to amplify a lower current density beam to generate a higher density one, (2) arrays of field emission needles or knife edges (these have been studied extensively but are still easy to damage and hard to use), (3) hybrid, laser-assisted and gated matrix cathodes using back illumination with lasers whose output matches the emitter array, (4) use of field emission from diamond films or other surfaces at higher pulsed fields (flat diamond films have been found to yield significant current densities with relatively low fields), (5) use of ferroelectric cathodes, or (6) new methods for bonding evaporated barium oxide in reservoir cathodes -- because evaporated material sometimes peels off and causes breakdown, improved bonding could increase the lifetime of devices using such cathodes. Grant applications are also sought to develop a sheet-beam, gridded, thermionic, dispenser-cathode gun for use in a 250 kV, 80 MW X-band (11.4 GHz), sheet-beam klystron. Parameters of the cathode are 100 cm2of cathode area, cylindrical or flat geometry, aspect ratio (cylinder length to segment width) of 2:1, and cathode current loading of 5 A/cm2. Grantees will work closely with engineers in the SLAC Klystron Department to match cathode design with klystron parameters. A gridded, short-pulse klystron may provide an alternative to a pulse compression system, such as for a linear collider. Lastly, grant applications are sought for research and development on gated electron sources with pulses or pulse trains larger than 0.1 microsecond at about 100-200 pulses per second, and on semiconductor photocathode sources of electrons with polarization in the range of 80 percent and energy in the range of a few volts to several hundred kilovolts. In addition, intensity stability <1 percent is required for polarized beams in pulsed linacs. d. Computer software¾ Grant applications are solicited for developing new or improved computer software specifically for the design or study of charged particle beam optical systems, accelerator systems, or accelerator components. Such applications should incorporate the innovative development of user-friendly interfaces with emphasis on graphical user interfaces and windows. Grant applications are also solicited for the conversion of existing codes to incorporate such interfaces, provided that existing copyrights are protected and that applications include the authors' statements of permission where appropriate. Grant applications are also sought for improved software for command and control functions, real time database management, and status display systems encountered in state-of-the-art approaches to accelerator control. In addition, grant applications are sought for improved management of integrated cost, schedule, and resource database information for planning and control of large High Energy Physics program R&D and construction projects, such as the Next Linear Collider. Please note: (1) The technical topics are to be interpreted literally; DOE personnel are not permitted to further interpret the narrative description of the technical topics. (2) The award selection process is extremely competitive. Last year, only 1 out of 6 grant applications were awarded. Only those applications with the highest scientific/technical quality will be competitive. References Bisognano, J. J. and Mondelli, A.
