Hello Ruben, 

Brian and I will start with the Pre-Power Up checks today. 
To complete with the full test for most of the 'Fast Dump- Hardware Interlock' checkouts is required to turn on the PSU to verified correct function of the dump switch and remote resets on the PSU. 
Will someone will be available to turn on the PSU after the replacement of the connector in the remote crate and re-tune of the QD units? 

Best Regards, 
Pablo

Gentlemen, 

Some of the I and C checks for pre-power up will have to be carried out in sequence (e.g. anything to do with the QD units): 

1. Replace connector on PSU remote control crate + complete both PSU check sheets - Onish (to be completed by Friday 18th Aug) 
2. Re-tune QD units - Probir (by Thursday 24th Aug) - as Probir is out Mon-Wed next week) 
3. Checks (including interlock checks) on QD units (by Friday 25th Aug) - Pablo/Brian/Nick - though of course you can make a start on the other checks 

As our cooling rate has increased (we are presently cooling at about 10 K/day), we won't have as much time as we initially thought so we should start as soon as possible. 

Regards 

Ruben
