Tasks:

Before Thursday - recovery from quench
Wednesday-Thursday 23rd Feb - SSU and SSD only, powered in flip mode; momentum scan for magnet alignment
Thursday 24th Feb - Sunday 26th Feb - magnets ramped to 2016/05 1
- momentum scan then emittance scan
- diffuser 4 stuck on highest emittance setting
Sunday 26th Feb - Tuesday 28th Feb - ISIS down for failure of dipole 9
Emittance Reduction

Magnet alignment¶

Noted issues with track extrapolation from detectors
For SSs only data, SSD was marked as solenoid mode in the reconstruction software; resolved, awaiting reconstruction reprocessing
For 2016/05 1 data, SSD Trim coils were marked as 0 current; resolved, awaiting reconstruction reprocessing
