Recent activity & Results update Thomas Pacey

Recent Activity ● Postgraduate Summer Showcase, Poster Presentation ● Variation in dielectric thickness & tunability ● Lab open week ● Back on VSim, results to come. . .

Lab Open Week Was involved in the corporate day, young school day, old school day and public day! 7500+ people came on Saturday for the public day. 320+ Saw the VELA Dome experience, non-stop at it all day! Collected good feedback

Results update Aiming to finalise key DWA structure parameters Focus on tunability & versatility Analytical treatment to ball park Large amount of CST data collected by Alisa from Lancaster Cluster Currently analysing and compiling into report

Variation of DWA structure Pure analytics Good agreement with CST VSim to come… Impact on manufacturing and peak fields to be assessed.

Analytics Comparing the data a = 100 micron δ = 50 micron Damping in CST is due to 3 D and wakefield ‘diffraction’ Will look into modelling CST Not clear why there is a factor of 2

A Strange CST Result, thin δ a = 100 micron δ = 50 micron Not clear why the transformer ratio is >2 Will cross check with VSim Likely a bug in simulation Not clear how this will

Future Trip to Cardiff Uni in August to aid CTR & MP-I diagnostic development More simulations to finalise parameters Look into de-chirping application. Important for FELs & LWFA & PWFA, recent Ralph Assman paper. . . Design phase for the structure control system
