Understanding MKDV Flashover Effects on Total Peak Current and Deflection Dynamics

This document explores the impact of MKDV flashovers on peak current and resulting deflection behaviors in magnets. Flashovers can result in varying peak current values depending on their location. Notably, deflections can range from half to double the nominal value based on MKDV interventions. For instance, at 47.5 kV using Q26 optics, the beam aligns on the graphite block, accounting for partial MKDV deflection. Conversely, Q20 optics exhibit different dynamics, highlighting variances even at higher voltages of 52 kV.

Presentation Transcript

  1. Dump in case of MKDV flashover • Flashovers in the magnets will cause different total peak current depending on where this happens • The resulting deflection is between half the nominal (one complete MKDV missing) or double the nominal (one complete MKDV more) one • With Q26 optics, above 47.5 kV the beam is on the graphite block, considering only half MKDV deflection • With Q20 instead, this is not the case anymore! (not even with 52 kV)

  2. Dump in case of MKDV flashoverHalf deflection from MKDV MKDV at 52 kV MKDV at 47.5 kV
