This research aims to evaluate the performance of HESR BPMs and the design challenges faced during testing.
Manufactured and tested 64 HESR BPMs using a purpose-built test stand.
Test stand accommodates BPMs of varying lengths from 450 mm to 1585 mm.
Measured properties like geometric factors and electrical center relative to the geometric center.
Presented measurements of various properties for all tested BPMs.
Discussed challenges that arose from design choices in the test stand layout.

Resumen

For the HESR diagonally cut BPMs were designed, with 64 manufactured and tested with a purpose-built BPM test-stand. This test-stand had to host BPMs of various lengths, the overall length of the complete vacuum system varies from 450 mm to 1585 mm. For all BPMs several properties, e.g. the geometric factors or the electrical center in relation to the geometric center, were measured utilizing the test stand. The results of these measurements will be presented together with the challenges resulting from the design choices made for the layout of the test stand.
