چکیده
In this paper, we illustrate the RF design and measurements of a C-band prototype structure for an Ultra High Dose Rate medical linac. (1) Background: FLASH Radiotherapy (RT) is revolutionary new technique cancer cure. It releases ultra-high radiation dose rates (above 100 Gy/s) in microsecond short pulses. order to obtain high very time, accelerators with high-intensity currents (the mA peak currents) have be developed. contest, Sapienza University, collaboration SIT-Sordina IORT Technology spa, developing linac achieve regime. (2) Methods: We performed electromagnetic C band using CST STUDIO Suite Code low power test at University Rome. The field cavity been done bead-pull technique. (3) Results: This device nine-cell operating on π/2 mode 5.712 GHz (C-band). report discuss measurement results full-scale copper prototype, showing good agreement simulations. A tuning procedure has implemented ensure proper frequency reach profile flatness few percent. (4) Conclusions: applications was successfully tested University. fabrication ad hoc procedures optimized discussed paper.

Design of an S-band Ultra-low-noise Amplifier with Frequency Band Switching Capability
In this paper, an ultra-low-noise amplifier with frequency band switching capability is designed, simulated and fabricated. The two frequency ranges of this amplifier consist of the 2.4 to 2.5 GHz and 3.1 GHz to 3.15 GHz frequency bands. The designed amplifier has a noise figure of less than 1dB, a minimum gain of 23 dB and a VSWR of less than 2 in the whole frequency band. The design process s...
متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
