[Hallb-solenoid] Solenoid and Torus Tasks

[Scot Spiegel]

Ruben, 

Refer to responses to your questions below. 

Also, I've repaired the Guard Vacuum PT8677. The current read-back is: 0.00 psia 

I informed Pablo C. about it yesterday before I left for the day. He confirmed the reading. 

Best regards,,

Hi Scot, 

How are you getting on with the following: 

1. Torus - ice management system - replacement of mechanical relays with SSRs 

T he upper heaters are active as of last night. I'll continue with the lower set this morning. 

2. Solenoid - flow controller repair and re-installation (?) 

Dave K. has requested this wait until next week... 

3. Solenoid - fitting socket head bolts to VCL voltage taps 
Replaced thumb screws with 10-32 X 1/4" hex head bolts & internal star washers ~ Completed 

4. Solenoid - Putting back front panel of isolation box on SST 

Panel & upper attachment bar are fitted and bolted ~ Completed 

Regards 

Ruben
