Thermal losses with the latest Al800 data. Gennady Romanov 2 nd Harmonic cavity Meeting 4/VI-2015

Latest data on Al800 garnet from Youri&Robyn. 4/VI-2015Gennady Romanov | Thermal losses with the latest Al800 data2 H min (35 A) = 7 kA/m; H min (40 A) = 12.7 kA/m kA/m will be a target. TD TD H field distribution in the set up at 40 A

Partially closed gap 4/VI-2015Gennady Romanov | Thermal losses with the latest Al800 data3 The partially closed gap is effective when it’s practically closed. Cooling of thick additional ferrite cylinder will be a problem. H field Loss density

Providing internal H min >12 kA/m 4/VI-2015Gennady Romanov | Thermal losses with the latest Al800 data4 μ ʹ =3-14, average μ ʹ = mm added Using higher starting bias field plus some moderate changes in the tuner dimensions internal H min was increased from 8.2 kA/m to 12.5 kA/m (103 Oe to 157 Oe, resonance is at 27 Oe for 76 MHz ). Loss density in the hot spot decreased by factor of 9. The plots look similar, but the upper plot is in log scale. Loss density distribution for lower bias starting level. Loss density distribution for higher bias starting level.
