Dear all,

We are running smoothly since yesterday this morning we increased the 
current from 45 nA to 50 nA. The operator yesterday worked on the 
optimization of our beam-line reducing the rates on both our upstream 
and downstream halo counters therefore the  number of trips. Also this 
morning, working with the PD to address the issue of beam current 
spikes,  a trim card power supply was changed for the vertical wein, 
this should help clear up those current spikes we were seeing. We will 
keep monitoring, the beam stability.

The plan for the next 24 hours is to continue production at 50 nA with 
no changes.

Tomorrow we will have our joined RC/TCB meeting. We will send an agenda 
shortly.

Best regards,

Latifa
