High power breakdown testing of a photonic band-gap accelerator structure with elliptical rods
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. An improved single-cell photonic band-gap (PBG) structure with an inner row of elliptical rods (PBG-E) was tested with high power at a 60 Hz repetition rate at X-band (11.424 GHz), achieving a gradient of 128 MV=m at a breakdown probability of 3:6 Â 10 À3 per pulse per meter at...
متن کاملPSFC / JA - 10 - 59 X - band photonic band - gap
In order to understand the performance of photonic bandgap (PBG) structures under realistic high gradient, high power, high repetition rate operation, a PBG accelerator structure was designed and tested at X-Band (11.424 GHz). The structure consisted of a single test cell with matching cells before and after the structure. The design followed principles previously established in testing a serie...
متن کاملDuplexer using microwave photonic band gap structure
We propose a frequency selective duplexer using microwave photonic band gap ~PBG! structures. It uses two different PBGs to control the propagation of electromagnetic waves in the microwave region. In this structure, an additional narrow reflection band appears in the transmission spectrum when the PBG structure is not properly located relative to the T junction. By considering multiple reflect...
متن کاملPHOTONIC BAND GAP ACCELERATOR CAVITY DESIGN AT 90 GHz*
In previous work we have proposed utilizing Photonic Band Gap (PBG) structures as a new class of high-energy, high-intensity accelerator cavities. We have completed extensive MAFIA numerical calculations of multicell PBG structures, with each cell consisting of a square array of metal cylinders terminated by conducting sheets and surrounded by microwave absorber on the periphery. We find that o...
متن کاملExperimental High-gradient Testing of an Elliptical-rod Photonic Band-gap (pbg) Structure at X-band
An 11.4 GHz photonic band-gap (PBG) structure where the rods in the inner row have an elliptical cross-section has been designed at MIT and manufactured and tested at high power and high repetition rate at SLAC. This structure exhibits lower surface magnetic fields on the rods relative to previous PBG structures tested at SLAC, which reduces the ohmic heating of the rod surface in an effort to ...
