Keith C Ng | ITE | Maintenance | | | measurement of new beam tube section |
R. Kuramoto and A. Laxdal measured the distance from the 2A tunnel to the tank flange of ITE. The new fabricated beam pipe with bellows was used to gauge the distance to the tank flange; The flange face of the beam tube was butted up to the tank flange and the beam tube was marked at the plane of the wall. A metal rod was used to gauge the distance to the tank face using the same method.
From the inside of the tunnel wall:
- To tank flange: 45 5/16"
- To ITE vacuum tank face: 49"

Anders Mjos | ITW | Development | | | Flow meters installed on Heat Shield and Coil water return |
David W. has installed two SST Proteus flow meters, model OV7006FTA32, on ITW Heat Shield and Coil. The flow meters are connected to a power supply and a data logger in the electrical room.
The Heat Shield flow meter has SN 00278112 and is on the Black wire pairs and connected to CH3 & CH4 on the logger.
The Coil flow meter has SN 00278113 and is on the Green wire pairs and connected to CH1 & CH2 on the logger.
The first channel (CH1, CH3) is temperature in degrees Celcius and the second channel (CH2, CH4) is flow rate in liters per minute.
A camera has been placed on the logger.
Flow rates today (2014-04-04):
HS 8.2 - 8.3 lpm
COIL 8.0 - 8.1 lpm
Calibration sheets
UPDATE 2014-04-11: Corrected HS to CH3 & CH4. |

Keith C Ng | ITE | Repair | | | 2a3 window - install |
Today:
1) Installed new cradle and shortened beam pipe section in wall penetration.
- Removed tank dust cover from flange and cleaned
- Held flange faces together from 2A tunnel side to check alignment, slightly biased to the East axially and a small gap present in the top when resting
2) Prepared new 2A window
- Connected preswaged (1/2 turn) swagelok nuts to the existing copper lines in the target hall, 1/4 turn from finger tight, 3/4 turns total
- Leak checked cooling lines with pressurized air at 75psi and snoop, no leaks were found at the joint
- Grooves were cleaned and helicoflex delta seals were installed with vacuum grease used in the periphery to hold ring in window, applied at 6 points every 60deg
3) Window installation
- Lowered window into position by cooling lines
- Window located into tank flange first then slid beam pipe towards it, capturing the window with seals
- Lowered clamp into place in hole
4) Clamp installation
- Lowered clamp into access hole and started closing clamp with steel RH drive bar
- torqued to 50 ft-lbs collar gap was still ~8"
- Increased torque to 60 ft-lbs then 70 ft-lbs stopped closing of clamp when the displacement did not change between the stop ring and clamp yoke
- It was decided not to continue to close this clamp, more assessment may be necessary
6) We will attempt to pump on the seal in its current configuration, tools have been removed. |

Keith C Ng | ITE | Repair | | | 2a3 window - He leak check |
Helium leak checked 2a3 window after installing using remote line:
- There was a leak found between the target and entrance module at the target pit, rate of 9E-6 atm-cc/sec.
- One test performed with the remote helium line to the window. There was a response but the leak detector was located above the window access channel, drift cannot be ruled out.
- 3 more tests performed with vacuum group, with leak detector relocated farther away from ITE and isolated with plastic. 2 tests using remote line had no response. One test done with a wand through 2a3 wall penetration had a response of 3.2E-9 atm-cc/sec (not using remote line).
Vacuum group (D. Yosifov) comments that due to the much larger leak at the top of the tank he cannot say with confidence the response seen is a leak at the window (due to leak at top) but if there is, a tolerable leak rate. |

Travis Cave | Spent Target Vault | Standard Operation | | 2A3 window | Window now in vault |
The 2A3 window now has a lid, and lift yolk on it and it has been installed in the spent target vault in spot 2A. The lid is a normal unmodified and has no sealant on it. |

maicodallavalle | Spent Target Vault | Standard Operation | | | F-308 Maintenance |
Five F - 308 flasks containing five ISAC spent targets were moved from the anteroom into the south hot cell area. When the F - 308's were in the south hot cell area the rest of the bolts were installed on all the top covers. All the bolts were torqued and all the cable locks were also installed. All F - 308's were then moved into the Active Services Area. |

Ron Kuramoto | ITW | Repair | | | ITW:IV5 Air leak repair |
Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room. The gasket between the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully.
Repair was done by Dimo Y. who received 0.01 mSv, and assisted by Anthony I. & Ron K. who both received zero dose.
Rad fields measured by RPG were; 1300 uSv/hr above B/L and 350 uSv/hr @ the Solenoid valves at knee height.
