The power supplies were "de-dusted" yesterday by Ray Dube and team. 

A flash and "thumb" was observed at the end of the mass scan.

Friday, July 12, 2013, 15:51: Ray Dube had a look inside. After the fuse was reset, the Power Supply could operate again.

A power bump was experienced at about the same time as the MB1 fuse latched.

Tuesday, August 20, 2013, 08:13: Roughing gas lines

Tuesday, August 20, 2013, 08:22: Gas lines roughed. Valve closed

TP1B high frequency noise is coming and going. Power is 22W , current 1.1A (other pumps are 11W and 14W, 0.7A)

Edi from vacuum group notified. He will replace the pump today.

Tuesday, August 20, 2013, 08:40: Turbos off. Vacuum 1.4E-7 T

Tuesday, August 20, 2013, 10:01: Started venting.

Turbo has been replaced by Edi.

Tuesday, August 20, 2013, 16:28: Roughing

Tuesday, August 20, 2013, 16:51: Turbos started.

TP1A timed out. Could not open BV1A and restart due to too high backing pressure at CG1A

Wednesday, August 21, 2013, 08:17: Turbos started. Vacuum 0.043 T

Wednesday, August 21, 2013, 08:25: Turbos at speed. TP1B: 1.2A 28W 30 deg C.

Wednesday, August 21, 2013, 08:27: Vacuum at 5.6 E-6 T

CG1A is climbing from 0.016 to 0.130 in 30 seconds when isolated.

The leak was confirmed to be between BV1A and PV1 in the bellows. The bellows has been replaced and backing pressure is back to normal values.

Monday, August 26, 2013, 14:07: The turbo could be restarted, but it does not sound happy (Dimo was consulted earlier today). The pump is drawing around 4 A. The current draw is fluctuating between 3.5 and 4.2 A at the same time as backing pressure is spiking from 0.015 to 0.045 T

Monday, August 26, 2013, 15:32:: The turbo failed again. Dimo had a quick look. It will have to be replaced. See e-fault: 6953

Wednesday, August 28, 2013, 08:48: Stopping TP1B. Vacuum at 4.8 E-7 T

Wednesday, August 28, 2013, 10:59: Venting

Anthony has replaced the pump. There was no screen on the existing pump. A screen has been installed in front of the turbo.

Jens Lassen provided a new controller for the Hall prove. With the help from Graham from controls it was reconfigured and is operational again. The magnet must likely be calibrated again.

Ray D. installed the "standard" 6V 200A FEBIAD COIL P/S on Friday morning.It has not yet been tested as water supply was on.
