Workshop Working Groups  

MM Wave Sources Working group
Group-Leader: Rick Temkin, MIT (temkin@psfc.mit.edu)
Co-Group-Leader: Glenn Scheitrum, SLAC (glenn@SLAC.Stanford.EDU)

The Theme is:

-Identify the most promising concepts for achieving High Power Output at Millimeter Wavelengths for driving future accelerators.

Working Plan:

The grand challenge in advanced accelerator research is to identify promising concepts for future accelerators. The High Energy Physics community would like to have an electron accelerator capable of reaching the TeV and multi-TeV range with the very high luminosity needed to obtain new data on a reasonable time scale. Millimeter wave accelerators combine the very attractive features of being able to achieve high gradient, while also being able to operate at high average power and efficiency. The high average power and efficiency issue go to the heart of our capability to build a real machine that can achieve the required high luminosity, thus making millimeter wave accelerators very attractive for accelerator applications.
After reviewing the state of the art of millimeter wave sources and auxiliary components, this group will explore the possibility of a future linear collider upgrade to a frequency higher that the NLC, and in particular identify the breakthroughs in millimeter wave sources and components that would be required.

The plan of the MM Wave Sources Working group is to:

1.) Evaluate the state-of-the-art in millimeter wave sources.
2.) Evaluate the state-of-the-art in auxiliary components at millimeter wavelengths.
3.) Identify and explore promising concepts for millimeter wave sources capable of achieving at least 100? MW of output power in the 35 to 100 GHz range.
4.) Evaluate the auxiliary components and technologies needed to implement the high power millimeter wave sources, such as power dividers, delay lines, etc.
5.) Evaluate the configuration needed for a millimeter wave accelerator system, such as an upgrade to the X-Band NLC.
6.) Evaluate modular sources that can be combined to achieve >10 MW at millimeter wavelengths. Lithographically fabricated sources can be produced in parallel on a single substrate along with the waveguide combiners. Alternatively, both sources and accelerator can be combined on a single substrate.
