The drive to reduce carbon emissions and reliance on oil and gas has led to the increase in the use of renewable energy heating systems. Ground source heat pump systems are an example of these renewable systems, and tunnels as a way of connecting building heat pump systems to the energy stored in the soil and air. Thermal tunnel energy segments were designed on the Crossrail project, London,...
The available amount of renewable energy sources (RES) such as wind and solar power undergoes daily and seasonal variations. To use theses sources in the best possible way, a corresponding modulation of the power requirement from the accelerator is beneficial. In the talk, some initial thoughts are presented about possible ways to modulate the ILC's power by changing between different...
1300MHz Solid State Amplifier that can provide 200kW of 1.6m sec pulse width at 10pps max becomes available with reasonable cost. The latest LDMOS silicon semiconductor devices, NXP's 800W-CW and 1600W-Pk devices, have been implemented and tested successfully.
This amplifier can feed each cavity, which eliminates the complex RF distribution system required for high power Klystrons (MBKs)....
The increase in efficiency of RF power generation for the future large-scale accelerators such as CLIC, ILC, FCC, CEPC and others is considered as a high priority issue. The vast majority of existing commercial high RF power klystrons operates in the electronic efficiency range between 40% and 50%. Only a few klystrons available on the market are capable of operating with 65% efficiency or...
