Failed....remains at ~2.3 (CATS1/VAMOS)
Fixede744s Mon Apr 15 18:23:57 2019 MarionVAMOSHardwareCH2Suggestion to follow the VAMOS Ewire as a function of time
A shift in the peak position of the DC_EWIRE page could allow to follow the drift chamber wire ageing.

VAMOS and MUGAST spectra were checked after the beam was back. Everything looks OK (e.g. similar to previous screenshots)

Waiting for beam again....
