A water leak on MB1 was found and reported by operations on June 10th e fault 7429
MB1 can not be switched on due to an TSH:MB1 water flow trip. Paddle wheel is rotating.
Wednesday, June 18, 2014, 14:03: Paddle wheel replaced with a used one from beam lines. Model SST150. Signal recovered. |

|
The read back of the ANODE current was confirmed to be working today with help of Ray D. using a 1kOhm resistor. There is an offset in the read back
which can explain why no current was seen on SiC#30. The resistor between CATHODE and GND was changed from 100 kOhm to 50kOhm. |

Travis assisted in installing a temperature reading RTD from Omega (SA1-RTD-MTP) on the water supply. The RTD has been installed with a 503 Ohm resistor
=> 0V = -175.75 C, 10V = 205.71 C. The RTD has been connected to Ch 9 on the data logger.
Offset calibration data towards the SUPPLY temperature reading is attached. |
